So using the 80TB * 1024GB/TB / 1800blades gives us about 45GB/blade. If they're using "simple SATA disks" this would imply internal disks and 1800 internal disks would have an aggregate throughput much higher than 5.2Gb/s (5.2Gb / 1800 = 2.95Mb/s per disk). Now typically you'd boot the nodes from the network (so you can change the identity of the node easily by booting it from a different image) from some sort of FC array accessed via an IB to FC gateway. However, 5.2Gbps is an odd number to get to since FC comes in 2 and 4Gb formats (1Gb fibrechannel is outdated and 2Gb is on the way out).
While I always see all the CPU details in these articles, I really wish they'd publish more about the storage requirements and methods rather than just staying (we have xTB of disk...). How do they back the finished datasets all up? Tape? MAID? VTL?
Pick your poison. Would you rather search Mars for 'cool pictures', 'colored rocks' or enable entire states to give their elementary school students paper/pencils and books?
because all the other stuff is reviewed by someone. But if it's entirely closed, you would have to trust the company. What if we, as a community thought that someone [else] was looking at a particular piece of code, when in fact nobody was looking at it? Like something out of Plato's republic, the greatest thing an unjust man [malicious coder] can do is to be believed to be just. Is it possible that someone reviewing the source code, could discover a bug and not disclose it, but instead use it for unjust purposes?
Even the old paper by Ken Thompson about Trusting Trust http://portal.acm.org/citation.cfm?id=358210/, discusses trusting no code except those that you write yourself. While this is not practical; the question becomes one on who(m) do you trust more? A company or the individual? Cathedral or the Bazaar?
Having the ability to see the source code to ensure safety is great. I don't agree with this. I would bet that very few users go through ANY source code at all. Editing.conf files or running 'make xconfig' not constitute 'going through the source code'. And those that do, probably wouldn't be able to know what's going on.
Let's say you're running a webserver (apache) which connects to a postgre database. Do you check all the code in apache+mods? filesystems? DNS? NIS? FibreChannel drivers?
How is trusting Redhat/Debian/Suse to make sure their distribution is safe any different from trusting AIX or HPUX? I don't want to have to be the one at my company that audit's 1m lines of linux code to 'make sure it's safe' we just trust our distribution.
'Web 3.0 is taking what we've built in Web 2.0--the wisdom of the crowds--and putting an editorial layer on it of truly talented, compensated people to make the product more trusted and refined.' Hmm, so this is basically get rid of the blogs/wikis etc and replace it with... let's call these "compensated people" writers, and require 'fact checking', then we'll have these people called "Editors" make sure the subject is on topic and appropriate for the given medium.
Damn, if these "Periodicals" come out daily, we'll call them newspapers; and weekly ones we'll call magazines. Heck even some of the highly technical ones we'll call Journals.
Shit, then people can go to school to become writers/authors or even Journalists. I bet a whole industry can sprout up from this. If the content is good enough, I'll even pay for it. I wonder if they can deliver it to my doorstep every morning by 7am, so I can read it with my morning coffee.
Ranger comprises 3,936 compute nodes in a Sun Blade(TM) 6048 Modular System with 15,744 Quad-Core AMD Opteron(TM) processors, and Sun Fire(TM) x4500 servers providing 1.7 petabytes of storage. Since TFA says this hardware will last only four years, what typically happens to these supercomputers built out of so called commodity hardware? Is sun going to donate/resell this gear? Or does it end up in the scrap heap? Surely, these Sun Blades are supposed to have a useful lifespan greater than four years. Sun could probably give these blades to every elementary school in all of Texas. Is the future of super computing aka disposable computing?
I practice Aikido, and the most difficult part of it is not to have your cognitive brain interfere when you're exectuing a technique against an opponent (or two or three...). It's what you practice in such Arts. Thus all the meditating and all that. It's really nothing religious - it's simply training your mind in the very same methodic and well-planned manner you train your body. I believe it's also referred to as instinct or reflex.
So let's say the music industry only sells uncrackable, draconian DRM protected music, such that it's impossible to make copies of it, pass it to your friends etc... This would force me to buy my music from them if I want it in any decent quality. Sure you could put a mic infront of your speakers, but it wouldn't sound good.
Without DRM, I could get high quality copies of the music from friends/bittorrent etc. Why would I then want to pay for the music, when I can get it for free?
If musicians want my money, tour.

Every night at 10pm we power off IP phones. We have about 10k phones on our main campus. These are primarily, lab, cubical, conference room phones that are powered off. We don't touch those used by tech-support, lobbies or breakrooms. We power them back on at 5:30am. We actually save quite a bit of power this way. Every windows system (we do have some linux/mac users) have softphone (software based phone) so you can make calls from your PC to call IT to have your phone powered back on (or not powered off at night if you work from your cube at night).
Also, in the 1993 film Gettysburg, for scenes such as Picket's charge, they would film a few companies of re-enactors, and then duplicate them to create Picket's division.
I drive a desk most days, and purchased a Logitech Wireless mouse. Not sure what protocol it uses, but I ended up trading it in for the wired version, as I was tired of hunting for new batteries every month.
So now it's possible someone will have at their desk/home:
-Logitech's Wireless protocol (http://www.mstarmetro.net/~rlowens/?n=Logitech.Protocols) -Bluetooth (which can be a PITA to associate two devices together) -Wireless USB -801.11a|b|g|n
All I ask is, can I have a few more wireless protocols? The first three do the same things. In LAN networking, we've gone through different speed iterations of Ethernet, I relish the day when 'short distance device connectivity' reaches the same maturity.
Folks, if you have not had the chance to do anything like this for yourselves, I suggest that you try it. The difference is staggering. The image opens up to triple it's original size. The depth of space pushes back, and opens upwards. The sound that was once sitting patiently inside the speakers stands up as tall as the ceiling, looming over your head and wrapping it's arms around you. It's nearly impossible to describe to anyone who has not experienced it. Y'know I was with you on this review, until you wrote the above fluff. It read like you were describing the latest and greatest wine...
When you buy a XBOX and sign up for XBOX Live, is there a SLA (Service Level Agreement) that guarantees uptime/accessibility? So under what grounds would you be able to file a class action lawsuit?
We've had the same issues with bladecenters and their integrated switches (LAN and SAN). The serverteam procures the bladecenters, and all the components inside. They then consider it their turf to manage the embedded switches. It turned into a political nightmare to wrest control of those switches away from them.
We're talking storage (sorry DASD) here... It's all about...
Hooking up a pair of EMC DMX's (or IBM ESSes, or HDS USPs) over a pair of OC48s for SRDF/PPRC/USR unless you are a zOS shop, then you could run XRC. Since this is a BC/DR plan, we'll run it over FCIP protected by IPSec over a DWDM leased line, which must be protected by a UPSR/BLSR, otherwise in the event of a link failure, the R1s will split from the R2s.
FTFA:
Mounting interest in these approaches highlights a pronounced shift away from "big-iron storage" - traditional storage arrays typically composed of custom application-specific integrated circuits, RAID controllers, and fixed-disk and cache-scalability ceilings. Now TFA goes on to say customers are turning towards Network Appliance as a company that uses COTS parts and software. They use an intel CPU and FC/GigE adapters from other vendors, but I wouldn't call them 100% COTS. It's not like it's a generic PC built from FRYS with JBOD on the back.
NetApp is a great company and makes a great product aimed for a specific market segment: Fileservices (NFS/CIFS). I don't see many customers tossing out the EMC DMX, HDS Tagmastore or IBM Shark for a FC enabled netapp array. I also don't see a lot of FICON shops asking netapp to support FICON.
Now the phase storage mgmt is entering is the 'good enough' phase. Does my organization need the current generation of "high end" arrays? Maybe not. The current generation of midrange with its better or cheaper $/GB and increasingly parallel featureset to the highend arrays, is starting to looking more attractive to many customers.
