Good Demo System For A High-Bandwidth Link?
FuzzyDaddy writes "My company is planning on demonstrating a 2.5 Gigabit per second link to some potential customers in the next few months. Now, we have all the equipment needed to measure how well the link is performing, but we'd like to put together a cheap 'Gee Whiz' demonstration. Surely other /.'ers have put together similar demos in the past. What combination of computers, network adapters, and software have you used to demonstrate high data rate links to potential customers?"

Download a dozen DVD movies at once and have them all display in real time? That would LOOK impressive at least.
What post? The one you're carrying inside your rusty innards!
then you may as well quit selling it. The fact is people who need that sort of performance come looking for it, everyone else can get by fine on 100Mb.
Use it to demonstrate how you can use a remotely mounted disk to simultaneously record/play a zillion-tracks Logic-or Pro Sound project.

just get a huge screen with tons of

with big screens. setup so you can
see all the screens from a few meters.
i wouldn't send one huge/large file, say
500 megs since even at 2.5 gigs/sec
it's going to take a while
better send/stream many mpg/avi/etc.
files. that should be impressive
Start streaming a large uncompressed dvd with VLC. While streaming, remote boot a series of machines off the network (all being console monitored on your current display) while showing live video of a monitor located on the other side of the link connected to the server you are booting/streaming from.
That should beat in the fact the bandwith is obscenely excessive.
--- I do not moderate.
See how many DVDs you can have going @ the same time. Copy some DVD files to a hd (smartripper will do this), and share them over the link. Use a software player like Media Player Classic if on win, or your fav player on linux. Load up multiple instances and see how many of the movies you can stream.
Also you can repeaditly stream a text version of War and Peace or some other lengthy book, with a counter on the recieving end showing how many times you have downloaded it. Keep a copy of the print edition on the table to show them what is comming down as the counter ticks away.

Unfortunately, you're going to have to run this 2.6 Gbps link to my apartment before I can show it to you. You see it's on my computer, and it's, um, nailed down. Yeah.... Nailed down... So, just show up tomorrow with the equipment, and we'll really surpise^H^H^H impress those investors!
Use PCI-X based cards to minimize CPU utilization. And of course, you should put a decent memory (fast and big enough) if you decide to buffer the transfer -- maybe a PC4000 512MB RAM. Then, if you decide to save the transfer or for the sending part, use a SCSI or SATA based HDD. Everything else can be el-cheapo based, IMHO. You can put a low-end CPU if the CPU utilization is low enough and then boast it in the demo. ;)
For the obvious, make sure you run OS with minimal background processes to reduce CPU overhead. IMHO http-based transfer works wonder for clients interested in "real-world" application.

I wouldn't know about computers and network cards and such, but as for what software to use: ask the marketing department (if you have one)!
If you can find out why your customers would need a 2,5Ghz link, and find the software that would demonstrate that your offering meets that need, you'll have no trouble selling it to them.
If construction was anything like programming, an incorrectly fitted lock would bring down the entire building...

i work at CITI and we've had recently done a few demos with our high-bandwidth link. one setup included two dell dual-CPU servers, one at either end of a gigabit link. we then used iperf to fill the majority of the link with traffic (using other machines). we then used a CITI project with the intervening Summit 7i switches to reserve bandwidth for a video teleconference. we demonstrated the practical capacity of the link and the ability to honor QoS parameters.
the CITI project used to manage the switches is, among other things, a secure remote invocation architecture that we use for a related network testing and performance-oriented umbrella project. that project's ultimate goal is to provide a distributed, real-time router-to-router traffic analysis system for use in optimizing campus networks and isolating networking failures. check our the web page if it's of interest.

Try loading up a server with 2TB of data and then do a full syncronization with a product like this. This should chew up more bandwidth than a simple file copy due to sync overhead.

Now, we have all the equipment needed to measure how well the link is performing, but we'd like to put together a cheap 'Gee Whiz' demonstration.
Speaking for myself, any additional "Gee Whizzery" would at best distract me from your take-home point -- that your network is really fast.
At worst, it would make me wonder why you were trying to distract me, and what you might be hiding, glossing over, or leaving for the fine print.
Now, there are a few things that you could do to make a more effective presentation. Despite years in the business, I still sometimes have a hard time grasping the size of Gigabytes, or remembering how Gigabytes compare to Mebibytes (that's not a misspelling; I'd include a link if I weren't typing on my handheld) to kilobits. I guess that.s why ls and df have a -h switch.
A nice chart showing your speed and bandwidth in terms of Tom Clancy novels per minute, or (umcompressed) Wagner operas per hour, would tend to bring those numbers home.
And for the suspicious, so would demonstrating downloads against encrypted and uncompressable data, so no one has to wonder how much of your speed came from on the fly adaptive Huffman encoding.
Basically, if what you're selling is speed and bandwidth, demonstrate that. Saavy customers aren't going to be swayed by booth girls or Barney the Dinosaur, and saavy customers won't want to waste time on that. If you're still aching to spend money, have a nice lunch delivered during the demo (after you've asked your customers about any dietary restrictions they have).
Opinions on the Twiddler2 hand-held keyboard?
Although I'm not a salesperson, I can give you this advice:
Someone in need of such a high speed connection will want it for some reason/application.
1. Find out what that application is.
2. Find out how they measure the performance of you product for their application. They will have some Key Performance Indicators for it.
3. Make a demo that shows the strengths of your product for _that_ application (include their jargon and KPIs)
4. Try to make it visually appealing (this might include additional streaming videos or book download counters as suggested by others here to insert a 'fun factor'. Who says demos need to be boring?).
Know who is coming to listen to / look at your demo. Techies will look for different KPIs than managers. Don't think what will impress you, think what will impress them.
Good luck
... the bandwidth of a truck full of DVDs
Now, if you could dematerialized said truck in one place and rematerialize it on another, that would be a suitably impressive demonstration of how much bandwidth you system can carry.
Do a 'time machine' demonstration. Throttle the bandwidth to, say, 56k and explain that this was 'The Internet' ten or twelve years ago. Demonstrate some moderately taxing application for the time (like a large download).
Take the audience forward in time by increasing the bandwidth slightly. Note how the previous application just zips by now, but start a new application that's still slow.
Repeat a few times going through a sequence something like: download large file, surf web, audio, tiny little image of fuzzy movie, voice-over-ip, real-time video with crappy quality, real-time high-quality video.
End the presentation with a question mark: every new level of bandwidth made previous uses easy, and enabled new applications that really needed the bandwidth. What will be the new application that makes you glad you have 2.5Gb?
It is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail. - Abraham Maslow
If it is to the Internet, then you're out of luck. 99% of anywhere you go couldn't come close to filling it.
Between remote offices? That is much better. It allows for things like multi-camera video conferencing or multiple simultaneous conferencing sessions.
It also lends itself to "location transparency" demos -- where it doesn't matter where in your system the resouce is, it acts like it is right at your fingertips.
For example, realtime video/audio editing of multiple tracks while the raw data is stored on a SAN in one building and the editing horsepower is in a different building -- and you're in a third just piping the interface.
Large scale CAD/Design reviews, with people being able to mark up and manipulate 3D imagery in real time, regardless of where on your net they're at.
Your big problem is going to be device latency. Spinning drives up, delays in software starting, etc. is going to be much more noticable. Bandwidth like that is great once the bits start flowing, but getting it started and keeping it filled will be taxing.
Unless you do testing that generates obscene amounts of data -- like collecting data from a supercollider, etc.
-Charles Hill
Learning HOW to think is more important than learning WHAT to think.
Eliminate all the possibilities that something could go wrong and make your company look inept, after all, you know the link works, so just assign a likely-looking IP address to the loopback interface, alias 'ifconfig' to one of your scripts that hides this fact, and voila ! You could even say "hmm.. it's faster than we thought.. we'll have to increase charges accordingly" :-)

2.5Gbps from a single server would be pretty fun to see. Maybe get a screen capture of that 200MB unreal tournament demo downloading. But at 320MB/s it would be "d'oh missed it"
But if its just 2.5Gbps distributed to a bunch of servers, then, sorry, I just don't see that as being too impressive.
Most decent data centers will have that kind of bandwidth. If fact for about $x0,000 any joe shmoh can buy themselves a couple of gige cables and a rack of servers from a good bandwidth provider.
You want to know what will impress your customers? Just ask them: "Hey guys, what is it exactly you were looking for?".
Me, being in the Linux Virtual Private Server hosting business, I want to see the following:
If your customers are looking at 2.5Gbps of bandwidth for an intranet backup solution then they'll probably be impressed by other things.
Do you really mean to say that you don't know what good your own technology is? One would think you would investigate uses that your potential clients would find beneficial, rather groping around slashdot for a wizzy demo.
Really, downloading a movie quickly probably won't impress most people in the slightest what with digitial TV and Tivo it will still just look like bad video on a computer monitor.
Now if you target your market for people who could really benefit from high speed internet, like for example, decreasing a companies national payroll download from a day to a minute, you might make some headway.
... how are you going to sell it?
Seriously if this 2.5 Gigabit per second link has any real business application for these customers then you should have no trouble thinking up uses.
I get that you asked for a gee-whiz type application but if the faster line is sooooo good surely then surely there's something in your potential customers business that will benefit from it. Nothing more gee-whiz than a solution to an exiting problem or a new oppurtunity for them.
Modify Mydoom.bleh to hit the server during the time that the clients are there for the demo? *shrugs*

When will I end this grieving ? When will my future begin ?
a company i worked at thought it was a great idea to stream copies of Episode 1 over the network to show it off. Never mind the fact that it was just released in theaters a few weeks before...
I was thinking that. When implementing backup systems in a previous job of mine I always used to find that the disk subsystems were the weakest link. 1 Terabyte in 7 mins would need some seriously impressive disk arrays.
People that believe in their opinions don't post AC.
If I've asked you to demo the link because I want to ship out data to my 250 locations in real time rather than overnight, or some other PITA time show me the link talking to >100 locations at once. Even if you're just sending through an arbritary file make sure its of the same order as the data they need to shift.
Show me that you understand what I need, I already assume you know what you have to sell. I need convincing that you know how to keep me happy.
And you can't assume I have ANY idea how much data is involved in sending HDTV or any other 'consumery' signal. I'd avoid TV as a demo at all costs! If my cable hookup and FREE set top box can handle it wtf does your big connection cost so much for???

Sure they can. I've seen plenty of arrays that can keep up with 250MB/s. In fact anything attached to a decent database server or used as central storage for a number of servers better be able to keep up that kind of throughput. For instance Netapp's FAS960C cluster solution can push 2.5GB/s on a synthetic benchmark

Definetly a nice streaming video demonstration will be the best. Persaduate management to buy few DV cameras and stream their data uncompressed (25 Mbps + audio), of, in example, demonstration meeting at one end of demo link to monitor and some cameras at the other end and back. Also you can add some spicy moments by adding a live feed from caffeteria or CEO and his secretary in live. They will be impressed, you will get a few pricy cameras to sell, a lot of new equipment that was required to set up a demonstration (think Sony W900 x6, dual opteirons x 3, Matrox parhelias all around, a lot of firewire cards) and will get at least some additional bonus, so you will have time to think about your job next time, instead of asking such questions in slashdot.

If you feel up to it, you can also suck up a little. If they're in architecture, art, film or music, take some examples of their work (not anything illegal or infringing,) encode them in insanely high resolution or bitrate, and get them off of your own server while you're there. If they're an engineering firm, go over to the US Patent Office site at uspto.gov and grab some high-quality pictures of the patents your client has been awarded. If they're a bank or brokerage or something dealing with numbers, show them databases the size of the entire state of Nebraska, after downloading them in just a few seconds. Lawyers and doctors need to access huge amounts of data (court rulings, medical records, what have you) so you could get online and show them how quickly you can locate obscure references. Educational institutions probably already have a nice big broadband, but access to online publications and research materials, as well as very fast and efficient inter-library catalog software running over the internet, can make the higher-ups in the school submit totally to your every whim.
Remember, if you're talking to managers, use the terms "efficient," "on-demand," "more/most cost-effective," and "the bottom line." Synergize!

Dear Mary,

OK so you can show your multiple DVD streams on it and download a CD at the same, whilst running a VoIP conversion..
How about having a T1 or a.n.other (45mbs) link trying to do the same thing. They need something to compare against.
Now compare the costs!
Stick a webserver on it and /. it.
Most businesses won't give a damn about video streaming, especially when it's possible with a 10 Mbps link - you should avoid even mentioning video unless they want to know about teleconferencing. You've got to provide them with reasons why they NEED that fast of a connection. A few obvious things are:
1) Connecting multiple offices together (with many hosts) so they can work in harmony instead of waiting hours to finish transfering something and playing solitaire while they wait.
2) Providing access to (a) storage area network(s) which could be used to store all their backups which eliminates the hassle of using tapes.
3) Connecting a HUGE number of hosts together with a few routers and tons of switches.
4) Providing room to grow.
If you can't demonstrate many hosts utilizing the link simultaneously, the next best thing would be to show one host transfering a backup of the OS or a large database. Just be sure that the computers you use have hard drives (RAID's if you're only using one host on each end) that are fast enough to keep up with the link.
Just do a simple comparison.
Download a file over a 100mBit or even 1gB and then do the same on the 2.5 gBit link.
Other than that its all numbers and figures about how many users a network using a 2.5gBit backbone can handle...
God, root, what is the difference?
If you don't have "another link" to contrast with, use something like dummynet to simulate a lower bandwidth/higher delay channel over your existing link, and use that as contrast.
Hmm. Three stories down, it appears as though Intel has a demonstration of "superfast communications technology in excess of 2 Gb/s" next week.
Coincidence? I think not.
Sounds like someone at Intel forgot to do their mental Kegel exercises. "It's done! It's amazing! It lives!" "Umm, wait a minute. How can we actually _demonstrate_ this?"

Ok, there is one thing that will impress the computer savy and admin types, that is real time remote disk mirroring. 2.5Gbps ~= 300MBps, or roughly the bandwidth of an ultra320 SCSI drive. Set up a single channel raid array with 9 drives on an U320 card plugged into a PCI-X slot. Mirror it to the other end of the link.
Then use the server for your daily uses, say file sharing or whatever. Demo the server playing DVDs, streaming across the network, capturing realtime video etc. Do both reads and writes.
When they ask what this has to do with the link, casually point out that all disk activity is happening simultaneusly on the other end of the link, and if the building is hit by an errant meteor or something, no data will be lost.
Then pull the plug on the raid array, and let the mirror take over remotely. If that does not impress them, they are not technical enough to understand what the point is anyway.
In that case, stream porn.

It doesn't matter, it's only a demo, the data can just go to /dev/null. The clueless knob-heads viewing the demo won't know any different.
At that rate you could easily stream a DVD, or maybe some HD-WMA or HD .ts files over it. That would certianly impress me. :-)
Load a station wagon with backup tapes and drive it across the parking lot. At the same time, initiate a huge file transfer. Display the transfer results as % of Station wagon loads/ft.
That should be clear as crystal and plenty gee-whiz enough:^)
My old sig was REALLY stoopid.
The parent poster is absolutely right. If these people are paying for an absurdly fast link, they'll probably be absurdly pissed when it goes down.
;)
Try to intersperse speed "gee-whiz" moments with tidbits about the reliable infrastructure. Talk about how their whole business rides on this link and you know how important it is. Serve a few gigs of content to 100 clients simultaneously. Show a diagram of the backup power systems that support every piece of equipment involved in the link. Make a remote backup of a big important database. Show how reliability is enhanced by the redundant fiber routes you chose, so there's no single point of failure. Do something that utterly flattens their current connection, and show how it doesn't even faze the new one. Then yank a card while it's running and show how 1:1 failover works.
If you've got a similarly absurd amount of CPU to throw behind this link, set up a cluster of Freenet nodes and watch it all slow to a crawl.
There isn't enough data in your post to suggest *anything*.
Is this a wireless link? Is it a LAN type segment? A campus/MAN type segment? Is it copper? Is it fiber? Is it cheaper than OC-48 (which is also a 2.4Gbps link, and has been in use for many years now)?

If you can really get the full throughput, then I think most people will experience a transfer of a full CD in 2 seconds as pretty impressive.
Or a DVD in 13 seconds. I believe Encyclopedia Britannica fits on a DVD?
Should be a nice demo to transfer the worlds largest encycolpedia in 13 seconds as well.
The problem is to find HW that can read 312MB/sec from disk and at the same time shuffle that out on the network.
Stuff like that are not easy to find...
I would probably put a machine on each side with 8GB of memory or huge ramdisks (BDS can for instance make a tmp fs that is completely in memory).
That way you, you get away from buying a horribly expensive disk RAID and save the bus/memory/CPU bandwidth needed from reading from disk.
three off the top of my head
1) Get a web server on that connection "slashdotted"
2) Write a DDOS virus to attack the customer's web server on their existing connection. Then, hook up your connection. Compare and enjoy.

Why not do something nerdy like having it calculate a bunch of prime numbers in a distributed fashion.
But there are certian older models of Cisco gigabit switches that catch fire if you run them full load for long enough. Perhaps you can find one of them and let out the magic smoke...
I would suggest that you give a demonstration, especially if you are selling execs, showing how this extra speed can save money. Say show them the speed it takes to Backup the system to an other system. Or ability to run a lot of software off a mount where you only need to install it one system. So saving administration time and perhaps license issues.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
I am part of a company that does real time monitoring, collection, duplication and modification to packets on connections like that. You will find that video is useful, but voip is the coming bandwidth hog. By demostrating that you can handle a very large number of conversations, it is impressive to those that will be interested in such a connection (large companies, Baby bells, Cable companies, and Government).
I prefer the "u" in honour as it seems to be missing these days.
Its one thing to turn on the echo ports and toss 1Gb back and forth to each other...its another to see what actual file transfers would be like. Of course, then you have to find disks that will keep up...

If you really wanted to demonstrate such a high bandwidth link AND really impress the clients, why not show them something really practical... Create an iSCSI based mini-SAN.
What I would do is use a software based iSCSI target like the one from Ardis Technologies and use it to share out a ram-drive. Obviously, you would need a machine with a fair amount of horsepower and quite a bit of RAM, but when you will be able to demonstrate transfer speeds of 250 Megabytes a second, that should be able to adequately show just how fast this link is.
You MIGHT be able to get that speed in a burst from SATA Raid or SCSI Raid, but I doubt you would be able to sustain it - this is why I am recommending a ramdrive.

Nice regurgitation of half digested technical articles. 3GIO *IS* PCI-express, its just the old name. Oh, and most PCI-X interface controllers have multiple DMA channels allowing you to send data in either direction. In this case a single PCI-X part at just over 500MB/s can more than saturate a 2.5Gb/s link so the fact that the bus is uni-directional during any single transfer is moot. The individual DMA channels have separate buffering allowing very clean and seamless DMA transfers at FULL speed. And BTW, most of this fancy PCI express tecnology you mention *doesn't exist* at the practical level today. The bridge spec was just finished in June of last year and the first compliance workshop was last december and this was for *baseline* PCI express implementations.
The bus has nothing to do with it, its the card and how it (Drivers primarily but also bus interface, buffering, etc) has been implemented. We transfer 300+MB/s sustained across shared PCI-X 100Mhz slots with less than 10% CPU load, the source is a second (133Mhz) PCI-X card that is feeding the two shared slots.
Make sure that the system you are using has enough PCI-X channels. Most motherboards that have SCSI/SATA down on the motherboard tend to share the PCI bus with the wrong slots. For this reason we run a 3 PCI-X slot motherboard which has minimal integration on the motherboard. This allows us to use one PCI-X 133 slot for the dual U320 SCSI controller (SATA isn't ready for this yet) and the other two slots to run multiple high definition channels (uncompressed) at 4:4:4 sampling. Thats quite a bit more bandwidth than we are talking about here. The system runs so clean that I have played Q3 in the foreground while all of this is going on. Oh, and this was all happening on Windows XP Pro.
I would also suggest that whatever you try to send, use UDP not TCP/IP.
Its not the motherboard, its not the OS, its not the slot. Its the engineering and not the kind that comes out of reading press releases.
That will be 11 minutes if you use the Lord of the Rings trilogy.
If what you are reading sounds funny, or sarcastic, lame, or stupid
it is because it is supposed to be. just laugh
but I'll post with my name anyway. I'm not afraid.
It appears to me that if you are asking slashdot how you can best use a connection this fast, you should probably quit your job and give it to someone else who would appreciate it more. The list of things I could show with a connection like this are just pure ownage, and even clients without a vag would find themselves getting wet. Metaphorically speaking of course.
You sir, are the troll for asking a question like this on Slashdot.
hrrm.
it's the system. If you're going to hook up a 2-node network for demo purposes, you'll be bottlenecked by the storage devices on the computers well before you can show what the network pipe is really capable of.
The only things I can think of inside a computer that can sustain 2.5Gb/s throughput are the front side bus and the AGP slot, assuming you have 4x or better on the AGP. If you're transmitting data, it has to come from somewhere, though, and unless you've got a VERY sizeable RAMdisk on hand, you're not going to impress people with moving files from one place to another -- you'll saturate the drive(s) the data is stored on well before you hit the capacity of the pipe.
2.5Gb/s is good for network backbones right now, and not much else. Well, it's great for anything involving data tranfer, obviously, but it's also overkill and therefore probably costs too much, and therefore not so great. But the performance, certainly, sings.
My best advice? Come up with some kind of network oriented demo that involves a many-node network, the nodes each equipped with very fast UltraSCSI 320 RAID-0 arrays so they can try to saturate the pipe.
You see? You see? Your stupid minds! Stupid! Stupid!
With such a bandwith, I would consider teleportation.
Nah, a video demo won't impress them.

Instead, case mod the equipment,throw in a lot of leds and stuff and go on the mystical tour.
customer: So, how fast is it?
you: This is state of the art equipment
you: (pause)
you: no demo would do it justice....
customer: (looking at all the lights)
I can't believe that in all the commentary so far that someone hasn't suggested you tie it to the customer's business interests/needs ? Are we all a bunch of technical engineers that don't know anything about commercial realities ? What kind of business are your customers in, and what kind of applications are important to them ? Is it sending large JPEG images to production houses ? Is it delivering software releases ? Is it video conferencing ? For all of the technical wizardly, all I can see is a lot of commercial ineptitude!
When my company has to demonstrate the speed of our gbps switches they always use uncompressed HDTV which is about 1.5 Gbps. Leaving you with 1 Gbps to fill, you could hook up some fibre channel drives and do some remote video editing or just copy a lot of files around.
Every demo should fake at least part of what is demonstrated!

Incidentally, if you meant 300 MB/sec, you're lying, since the PCI bus only pushes 133 MB/sec (theoretical max). And there's no way that the spindles on those SATA drives can actually push the bandwidth of the SATA 1.0 interface.

Back in Napster's hey-day, I knew of a guy who, when answering the phone to customers, would ask them what their favourite song was and then try and pull it off Napster while he was talking to them. Napster + 10Mbit internet connection + a cable from line-out into the phone system, and 80% of the time customers on hold would find themselves listening to their favourite song. Now *that's* a neat bandwidth demo :)

You'll need a monster machine to handle that bandwidth, probably a dual itanium or dual opteron at the least. Maybe the Tyan Thunder K8 dual opteron board, with dual PCI-X NICs feeding into your switch.

I agree with all the posters that say "if you dont know what application it is good for, then there is a marketing issue here".
...etc.) then there may be a need there.
When you guys built it, there was some need in the market, and not just "pure bandwidth". Who are your customer? ISPs? Telcos? Who?
having said that, something that customers often ask is how to replicate a database in real time, so if one datacenter is hit by a quake, the remote one takes over in seconds. This often involves complex database tricks (Oracle has that, we looked at it a few times, and bandwidth was the issue then, a few years ago). Even storage vendors like EMC have the ability of a SRDF (Symmetrix Remote Data Facility) that replicates data in real time to another storage unit. If you have an appliction that does thousands of updates per second, and a lot of other traffic going on (e.g. off site backups, image/video traffic,
So you may setup a huge database with lots of updates on one end, and replicate that in real time on the other end, the pull the plug on one, and the other one should pick up (e.g. for a pool of web browsing clients, and a director in the middle or something).

There is a good chance that the technology that he's trying to showcase IS PCI Express and he's having the problem most people are in trying to sell it. How do you convince someone they need more bandwidth when you can't even fill the pipe to demonstrate how good it is?
20-30, and then tell them you're using 10% of the line's capacity.
You're just trying to sell the technology anyway, do some number crunching and determine how many live full sized DVD quality video streams you could conceivable handly, use Canadian math (double it and add two, eh), and set up that many PC's with hidden internal DVD drives playing movies like The Matrix, and Lord of the Rings. Label the DVD drives with names like "UK_FS_01" or "AUSSIELINK", and away you go. They won't see any slowdown, and they'll appreciate your proper geeky choice of movies.
Apologies if I missed an earlier comment that got this right. The way I see it, you need a demonstration that only works at 2.5GB/s, and no slower. IMHO, streaming video is no good, because you can always buffer it, drop frames, or otherwise compensate for slower transfer rates. Backups don't work, because you can do them on a slower connection; it just takes a little longer. The remote robot suggested earlier is on the right track, but it may not be transferring enough data in both directions to require the full 2.5GB/s.
So, what application needs to transfer that much information that fast, and no slower? I don't have a definitive answer for you, but maybe someone else on SlashDot does. I suspect the answer is in real-time data collection, simulation, and/or prediction. Think tornado forcasts. Think earthquakes and tsunami's. Think real time stock market forcasts (this may not be enough data). Think real time disaster effects and emergency response, like a dirty bomb or a new volcano.
Now, when you think you have the right application picked out, test against a shorter alternative pipe; say, 100MB or 1GB or whatever you propose to replace. Will your application work --even in a degraded fashion-- on the slower pipe? If so, it's not right for you. Make the application more demanding, or choose another application.
When you have the demonstration application picked out, please post it back on SlashDot.

..this idea, coupled with the "time warp" of another post would be a great idea, especially if you could manage to display HD video.
Start out with what video on the internet looked like back using dialup in 1995 -- postage-stamp sized 8 bit windows running at 8-10 fps with out-of-sync 8Khz mono audio. Move slowly up the resolution and link speed until you get to "today's streaming video", but still displaying only one window of video. During this time, keep the display at something smaller, like 800x600 on a larger display; partly to magnify the pixelization of older/slower video, partly for greater wow factor later on.
At this point, you start talking about your link and you switch the video feed to HD full screen. "And that's not all...." -- switch the display to max resolution (2048 x 1536?), and start adding HD feeds until you've tiled the screen with HD feeds. Keep adding them until you have so many on the screen that they're hard to see or you really have maxed out the pipe.
This is something that ordinary people can grasp; the challenge will be a computer with video display capable of displaying dozens of simultaneous HD feeds, but it will look really cool, especially if you keep the sound going on each station and gradually increase the volume as you add channels for dramatic impact.
I think the important thing here isn't the 2.5gbit link itself, but how it performs in comparison to other highspeed connections.
If you have one computer (the one on the 2.5gbit link) streaming 300 DVDs in realtime, and another computer streaming 1 with an exremely jerky and possibly laggy DSL/cable connection, it will allow people to grasp the depth of the situation. Just showing that it's blindingly fast won't do anything for you if you can't provide a baseline from which the average joe can compare.
Somebody else suggested having it download "war and peace" over and over, while having a hard-copy sitting nearby so you could have something tangible to say "All of this information is being transferred from office to office in a matter of seconds. With this kind of highspeed link, e-mails with attachments the size of the statue of liberty would be received almost instantly." etc.
Geeks know what 2.5gbps gets you. Real people don't, and you need some way to contrast the power of their current internet connection with the power of the new proposed one.
Doing multiple things at once, if not the playing of multiple DVDs, is what's going to win people over. Streaming video gets the layperson response of "My TV does that" (as another commenter pointed out). However, if you can have a computer displaying every single cable channel available all at once or something along those lines, then THAT would be impressive to the average joe. Or perhaps a video conference with hundreds of remote parties? Each client connection would have its own bi-directional video stream, such that the clients could see the person doing the presentation, and the person presenting can tile 100 windows on a 2048x1280 (or whatever high resolution) screen, all showing a different person in a different place all in fluid motion, in realtime.
Reinvent the wheel only at either a lower cost, greater effectiveness, or your own personal enrichment and satisfaction.
Most suggestions thus far are very cool suggestions... from the point of a techie, but to a management user or a user who is not as technically inclined. Seeing one thing (such as downloading a DVD) and not having anything significant to compare it against is really bad.
:-)
A good idea would be to have the fastest connection these guys already have compete against this connection for uploading/downloading something (backups, movie, etc.) and have the status display behind you show just how amazingly fast this new line is. Since they already know that the "old" line is really fast, this should really blow them away because then they'll have something to compare your new line to, and thus they can really see what this new line can do for them.
Management usually aren't techies and don't understand how much bandwidth a movie takes up, but they do know how to compare things, that's their job. So, if you do a comparison presentation, I can bet it will go over really really well.

History of Grits.
I did a high-speed network protocol (Scheduled Transfer Protocol on GigE) demo a few years back, and to get something more interesting than a text console showing a transfer speed of 100MB/s (crappy 32-bit/33 MHz PCI buses and PC100 memory :( ) I did a quick&dirty video transmission thing.
:-)
What I used was just some random ~= 2Mbps video clip, but to get the bandwidth use up, I split the file into blocks of 1 MB, transmitted each block 500 times or so and the receiver chose a random copy of the block for playing the file back.
Avoids the slow disk problem yet lets you send "500 videos at the same time". It took something like 15 minutes to hack this feature into the network benchmark tool I was using

What we are looking for is an eye-catching way to demonstrate actual working technology. We're not trying to demonstrate that what we're offering is useful - they know that - but were trying to get them interested in it by showing them working prototypes, so they go home knowing we have real hardware.
What I'm looking for is a simple demo - if I'm doing video streaming, what hardware and software could I get that would be relatively cheap and easy to set up that would demonstrate the technology is working? What NIC should I be using? What OS? What sort of memory? What kind of performance could I expect out of an off the shelf PC?

my old employer was an early adopter of an advanced networking tech (i was under an NDA, and i think it has finally gone commercial) that daisy-chained computers together on a 800mbps bus. apparently this network was 100% efficient, with no possibility for collisions etc., etc. it could theoretically scale to hundreds of systems with no loss in throughput.
they were going to demonstrate it (after i left) as part of their renderfarm. they were going to run several test renders with lightwave on all the systems to show off its speed.
never heard how it went, but it's an idea.

My experience with TCP/IP under Windows indicates that it is very difficult to get more that 150 MBytes/Second from a single box (and I was using a specialized app to get that speed). I don't know what kind of delays the link imposes, but if you are using TCP/IP for the benchmark, be sure to enable scalable windows (search for RFC1323 on microsoft.com).
Another way to look at this is that PCI-Express links run at 2.5 Gbits/second. If you built something that ramped PCI-Express packets to/from your link, you could have an interesting I/O technology (comparable to Infiniband).
As others have pointed out, this sort of bandwidth is comparable/greater than most disk drive subsystems. Interesting demonstration is to use something like iSCSI to talk to disk drive that are on the other side of the link, and perhaps run some disk benchmarks, etc. Current (affordable) iSCSI controllers can push 60-80 MBytes/sec, so you could put 4 or 5 workstations on one side, and multiple iSCSI/iFiber routers on the other (with a bunch of iFiber disks).

Practically all video conferencing software I've seen so far has a slight delay. The software always seems to attempt to compress the stream. Uncompressed then a remote digital feed would have the responsiveness of a camcorder. First make it high resolution (at least 640x480) and then make multiple screens of it. Live high quality feedback at the speed of light over the internet would be cool to me.

That means, in the 30 seconds in took me to transfer that DVD, 3375 floppy disks worth of information could be transferred. That means, every employee could download a floppy disk of information every 30 seconds all day long, and there would still be available bandwidth."
You could even mention how 20 MS Word documents can fit on one floppy (depending on size), and explain that not everyone will be downloading all that data at the exact same time, thus improving the transfer speeds for the other users.

The best way to eat grits in my humble opinion:
1> Cook up some grits. Don't go for that instant stuff. Go for the kind that actually take time on the stove to make. Flavor 'em with a little salt and butter.
2> Fry up some bacon. Get it good and crispy.
3> Fry two eggs in the bacon grease, over easy. Really over easy -- you want the yolk just barely warm and some of the egg white still gooey.
4> Obtain two slices of Kraft American Cheese. The processed kind, that comes individually wrapped in cellophane.
5> Chop up the bacon into small bits.
6> Serve up a helping of grits onto your plate. Mix bacon into grits. Place fried eggs on top of grits, and cheese on top of fried eggs (unwrap cheese from cellophane first).
7> Using edge of fork, cut up cheese and eggs while stirring into grits. For good measure, stir in a little bit of that extra pork fat. Season to taste with salt and pepper.

2.5Gbps (2.5x10^9 bits/sec = 298MB/sec), which is slower than U320's transfer rate of 320MB/sec. Then there's fibrechannel. And most systems that use these harddrives have RAID arrays that increase the overall transfer speed anyway. So that's how you can use 2.5Gbps with one system.
But... A 2.5Gbps typically wouldn't be used for a single machine. Behind that connection would hundreds of computers each using their share of the bandwidth. Maybe a colocation site. The colocation site I use houses about a hundred servers each at 100Mbps.
100 servers X 100Mbps = 10Gbps.

If that doesn't bring the link down, nothing will!

They've spent the last few weeks re-engineering the site to handle some unusually high throughput.

If you're talking just streaming some big video files, even a single FAS960 will have no trouble saturating a 2.5Gb/sec link. For example:
filer04*> sysstat 2
CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache
in out read write read write age
12% 2664 0 0 557 406 44 0 0 0 34
73% 27430 0 0 2878 87207 13236 0 0 0 34
100% 37447 0 0 6597 317242 2823 0 0 0 34
100% 37265 0 0 6390 315388 3120 1741 0 0 34
100% 37453 0 0 6386 316227 2518 0 0 0 34
So over 300MB/sec even with 8K blocks, and this is a single 960. I generated that throughput with 6 boxes reading 6 seperate 2GB files. I was actually surprised to see that on a dual-Opteron 246 box I was able to read a stream from the filer at about 92MB/sec.
So I guess today's ultra-fast PCs can indeed move some serious data. Of course, if you don't have a badass NetApp filer you may need to think up some other way of delivering that kind of data rate from disk. Otherwise as someone else suggested a pile-o-RAM and a simple tcp server would do the trick.
find some nice young ladies to run cyberdildonic and net camera devices simultaneously.. that much bandwidth, you should be able to have quite a stable of chicks, and properly done, make a few bucks on the company budget as well..

Send random data to populate any leftover bandwidth.
Try a remote backing up a system and have it complete within 10 minutes which another similar system is backing up over 100TX and tell them how how much longer this other system will take after your system has finished. QOS it.
Run a system streaming different DVD videos to 10 or so computers using QOS. Whatever would fill up a standard 100TX line. Then tell them how many independent video streams you could serve, which I'd guess would be around 300.
Also have about five free desktops with a broser on screen. This could demonstrate QOS and how they aren't appreciably affected appreciably since the internet itself is so slow. Explain how many people it would take, based on adverage cable modem usage by home users, to saturate your line (not your uplink).
A digitized libary of congress is about 10 terabytes. Tell them how long it would take to transfer it between computers at your speed rates. It obviously won't impress them. If my math is right around 3 hours. Then tell them how long it would take to download at other speeds. 100TX would be around three and a half days.
Roughtly what broadband is to modem, your line is to 100TX.
Who cares how fast it is... can it survive a Slashdotting?

First of all, PCI Express is an implementation of parts of the 3GIO specifications(For example, PCI Express only allows for implementation on a PCB, i.e backplane, while the full 3GIO supports linking systems via fiber-optic cable).
As for your comments about PCI-X, not all implementations of PCI-X supports that, and you're still dependent upon transfers between various units, and RAM etc. DMA channels don't matter much when you've still only got that one physical conncetion and it's half-duplex. And using UDP is a hit-or-miss proposition. Any packet loss on the way, and the demo won't look quite as good
I used to work for Tektronix. You could have a sales engineer measure your performance while you demo your equipment. Sounds like it would be good for both of you. ay
A friend at McGill university is writing code that has been used to demonstrate 2-way video conferencing with uncompressed video and 12 channels of uncompressed high-quality audio. With this software, they've managed to have musicians in Ottawa and Montreal collaborate in live jam sessions. The demo's have been quite impresive, and you can get the code here. (Not yet open source, although they're working towards that.)
Hey Man, I was in USA before 9/11, and also after, and I saw the change in attitude in Americans. It was pretty dramatic...and even after their two tallest buildings get knocked down by a bunch of jihadi scum, they still haven't figured out why the rest of world hates America so much....U think they would finally wake up to the fact that they fucking preach democracy and freedom and blah blah blah and practise the absolute opposite. They praise China, a communist country who mows down its citizens when they ask for freedom. They kiss Pakistan's ass, when it's clear that all the WMDs and Al-Qaeda connections which were meant to be in Iraq are actually in Pakistan.....It would still be ok, if this was just government policy, and the regular joe would disassociate themselves from this...but no...the avergae American is raised on a diet of sensationalist shit media, and thus believe every word of what their newspapers and media say just like in the USSR. CNN is just a frikkin' propaganda channel....forget freedom of speech. Before 9/11, at least the software industry used to be colour-blind and a shining example of the fact the world can be a better place where everyone can live together, with tolerance and propserity for all....but now the American Software community (at least based on the Slashdot posts, I can't speak for the rest) seems to have given into the same xenophobic mis-informed shit that their media and their government spreads. You know, outside America, EVERYBODY KNEW there were no WMDs in Iraq, and no links to Al Qaeda. It was fucking obvious. THIS is why we were all reluctant to go to war. There are worse terrors in the world than some dumbass dictator who abuses his own people....Pakistan and Afghanistan are the MAIN DANGERS to the world, Osama's outsourcing of terrorism to these two countries is a little more threatening than Indian software outsourcing, take my word. Afghanistan you guys took care of, good on you. Now fucking finish the job off. Bush, may the bastard get butt-fucked by the Taliban, said "Either you're with us, or against us". Is Pakistan for or against u? Does a country that sells nuclear secrets to all of the members of your Axis of Evil qualify as an Ally? Has the definition of ally changed? I'm sorry I can't find a grey area here...but then what do I know, I'm just someone from the land of towel-heads...although I've never put a towel on my head except to dry my hair....
To the poster I've replied to, thanks for showing some solidarity, we Indians are in need of that these days. Fucking Americans will never understand that we could be good friends to them, and it would benefit both our countries... their loss. Instead they choose to ebe jealous and racist about it. A real shame to see the "Greatest Nation on Earth" stopp down to the level of those same prejudicial countries whom they mock.
