the Apt/RPM is a huge difference. I used to love Fedora, and (still) run RHEL at the office on our servers. RHEL is fine, as I don't play and experement and try new things on it, but Fedora got to be a real pain in the ass with RPM Dependancies. I would find an RPM of something I wanted to install, it required me to first find and install another RPM, etc. Sometimes one of the dependant RPM's would not install, because I had a newer/older version for another program. Apt-get has worked flawlessly for me, and the HUGE pool of apps that just work has made it so I almost never have to search for.DEB files. I think the only change I had to do was add google's APT repository to Ubuntu, and it keeps picasa and google-earth up to date.
If the RPM system gets a huge makeover, I would probably play with Fedora again. It may have already been done, I switched to Ubuntu at 6.04.
It has a huge advantage. Next time MS threatens to raise the price of your Volume subscription, you threaten to move a few thousand more machines to linux or apple. They back down. Next time apple threatens to raise the prices of their software, you threaten to move a few thousand machines to windows. Many companies bitch about the costs of licensing, but its just bitching, since they don't see themselves as having a choice. IBM will have a choice, and can shop around to get the best prices.
If the college is a state college, it completely invalidates the mentality of "I'm paying for it!". That is crap I hear all the time at the college I work at. The truth is, while you pay $x/credit, plus fees, the state pays a much larger portion of your education. Basically, look at the tuition at a private school, then at a public school in the same area. Figure the state is paying close to the difference. The saying that "I'm paying for it, so I can whatever if I want" pisses me off, because I'm also paying for you to go to school, and I am paying for you to repeat those stupid classes. My college costs about $650/term in tuition for a full time, and gets roughly about $700 in state reiumbersement (per FTE/term). This is from Oregon, where higher education funding is in the bottom nationally. Most states have an even higher ratio.
You don't need to actually buy anything for block storage.. There are open source iscsi target drivers for most operating systems. Most also have initiator drivers.
You do know that mozart was deaf, right? Should he have been excluded/discouraged?
I got to sit in a meeting, where a college accessability person was talking about the work they were doing to make their site more "accessable". (note that is a general term). Their research found that a few simple changes not only made it easier on the blind, but for many other disabilites, and made the site far easier to navigate as well. For example, a page has a next button at the bottom of the text. The blind have to wait forever for their screen reader to get to it, the people with Carpal Tunnel syndrom have to move their hands much more, and many other people have to scroll down past all the text to find it. His main point was, as their site became much easier for the disabled to access, it became much easier for non-disabled to access, so users were spending less time on the web site searching for the info they needed.
It is usually recommended to run a seperate network for the storage network. It is possible to run storage over the same nic that the server uses for other network traffic, but is not recommened (but is used often as a "failover"). This also helps when you turn on Jumbo Frames, some servers just don't like to work correctly. Seperate network makes it better.
However, the best advantage of iSCSI over FC is replication. How much extra infrastructure and technologies do you need to replicate to a site 1000 miles away? Compare that with FC, and its special software and hardware to do replication over TCP/IP.
The previous reply was good, just wanted to expand. File access is literally grabbing a file over the network. Like opening a word document. It pulls the entire file over the network, then opens it.
Your hard drive is a block device. A SAN just uses some protocols to make the OS treat a remote storage as a local disk (Think of it as scsi going over the network, instead of a local cable, which is almost exactly what iSCSI is). You can format, defrag, etc. The OS does not know that the device isn't inside the box. Very usefull for things like databases, because you just modifiy the blocks (think of it as clusters/sectors on the hard drive that need to be changed.
Also, block storage is usually dedicated to a particular server, so you don't need to worry about "locking" a file that is open for changing like with NFS to ensure integrity.
I love using linux as my desktop, converted about a year ago, and have not looked back. However, at my office, I have to use/administer windows. I have got to say that the one thing Linux lacks as a desktop in the business world is group policy (or something equivalent). I can't tell you how nice it is to have one spot on the server to configure password policies, proxy's for browsers, printing defaults, and application settings for all client computers. Not to mention a quick dirty way to deploy software out.
Wow, last time I had problems was a few years ago, back in my XP days, I installed XP sp2 from the CD. It didn't know what my SATA card was. It was a re-install, and I had thrown away the old Mobo disks. When I finaly found the correct drivers (on my laptop) I could not procede until I inserted the floppy with the correct drivers. I don't have a floppy in my desktop, or laptop. That took a good day to go scrounge up an old 3.5inch floppy, to install an OS. Also, I tried pluging a generic webcam (bought off ebay for 5 bucks) into an XP machine. It couldn't find any drivers, and the camera had no identifying information on it, so I couldn't find any. Ubuntu didn't care, and it just works..
As the previous poster mentioned, our civil liberties we have been gladly giving away. However, it is not just the last few years, but for quite some time now. (but it has accelerated greatly). First, it was to protect us from drugs, because everyone that used Pot would turn into a crazed animal that would kill your daughter and rape your golden retriever. Then it was to protect the children. Have a kid claim you hurt them. Your treated as guilty until you prove yourself innocent!
You obviously don't understand digital. Digital is all ones and zero's. If you have a kink in the cable, because it is made cheaply, then the 0's, being as they are round, can slip around the kink's, but the 1's, having sharp edges, pile up.
Or, your a good sysadmin that doesn't treat storage space like a VB programmer treats RAM. There is no such thing as $6 of storage. There is $6 of storage space,replicated on the San, backed up to countless tapes, replicated over a relatively slow WAN to another site. There is also 30GB of downloads going over the company's internet connection that have no business use. There is also another 500 users, and if they find out Joe does it, at least 10 percent of them will want to as well. Then of course, it could just be that your a good sysadmin, and were investigating why your backups took an hour longer to finish last night than normal, which really messes with your backup window.
I hate those titlebars. Why the hell not make it 16:9? I go to the electronic stores, and I can't understand why at 50" TV that is widescreen, has black bars at the top and the bottom?? Why not just then get a proper 42" widescreen, cause thats all your really using..
You know, one of the points were not talking about is cross polination. That is not a good thing. What happens 20 years from now when they discover that GM'd corn causes cancer? Because of cross pollination, there will be no more non-modified corn anymore. And befor people jump all over me, remeber how long it took to figure out the dangers of Dioxins, and PCB's. (Both of which Monsato made!)
True engineers have much higher responsibility/accountability attached. Nobody cares if your program crashes (hence bug reports, new version, etc) but god help you if a bridge collapses because of a stupid mistake, and you're the engineer that signed off on that design. At a minimum, you'll lose your license, and have to find a new line of work. Now that I think of it, that would be good for some "software engineers" I've talked to. Most real "engineers" have the knowledge that screwups will kill/hurt people.
Its made by montster. So its a premium UPS, with about a 80% markup in price (or 800%). But if you ask someone at best buy, they'll insist it will make everything sound "high def" And it probably doesn't include the Monster premium titanium power cables to plug into the equipment.
And what happens when you do that, and the log truck hauling 40,000lbs of logs is behind you? Or an idiot in a suburban is fiddling with the radio, or on the phone, and coming up on you real fast? Sure, you're in the right, but your children/friends in the back seat are dead. There are times when it is, in fact, safer to go out into the intersection. The camera doesn't excercise judgement, just that you were in the intersection.
But laws are never repealed. In my town, it is illegal to whack the heads off of snakes downtown. See, 100 years ago, there were boardwalks downtown instead of sidewalks. Snakes liked to live under them, it was cool, and they would stick their heads up between the boards. People would kick or wack at the heads, the snake would fall down dead, and really start stinking after a few days. Is there any reason that law still needs to be around? There are many other laws that are like that. Do they show the philisophical beliefs of the majority? (What about anti-sodomy laws in the south?)
But the FCC is doing the opposite. They have been cracking down on places like restruants that put in devices to block cell-phones. It isn't even the "A doctor might be sitting in the theatre watching a movie while he is on call for a heart transplant" kind of argument (which is really stupid, think of the children), its "Company Paid for a national license, we are here to enforce that nobody is blocking that license anywhere". If a restruant, or airline, or whatever wants to allow the use of cell phones, and lets people know, groovy, but if they choose not to, that should be respected also.
As much as I hate it, some great software has been developed under the Copyright system that otherwise might not have been made. A solution? I don't have it.

I don't know about VMWare server, but I do know that MS recommends Block storage over file storage for Virtual Server 2005. Ask VMWare.
What happens in a few years after Cat9 is no longer sufficient? Everyone knows cat's only have 9 lives..

Never argue with an idiot. They'll bring you down to their level, and beat you with experience!
