World's Five Biggest SANs 161
An anonymous reader writes "ByteandSwitch is searching the World's Biggest SANs, and has compiled a list of 5 candidate with networks supports 10+ Petabytes of active storage. Leading the list is JPMorgan Chase, which uses a mix of IBM and Sun equipment to deliver 14 Pbytes for 170k employees. Also on the list are the U.S. DoD, which uses 700 Fibre Channel switches, NASA, the San Diego Supercomputer Center (it's got 18 Pbytes of tape! storage), and Lawrence Livermore."

If I remember correctly, these guys will generate petabytes of data per day when that monster particle accelerator goes online in a few months...

If you add up the total disk space in an average office you'll get more than that. If I add up all my external disks, etc. I've got more than a terabyte on my desktop.
(And yes it's true, data does grow to fit the available space)

Exactly why shouldn't you have end-users plugged into a SAN? I run a SAN, and I find that diskless workstations PXE booting off gigabit iSCSI storage are a huge improvement to having local disk. For more or less exactly those reasons; performance, redundancy, flexibility, growth and sharing. Not to mention data consolidation and savings in less wasted local storage.
I suspect the idea that SAN's are for servers is mostly spread by overcharging SAN vendors who dont want their profit margins eroded by inexpensive consumer devices. In fact, I'd say consumer storage is rapidly progressing beyond the server side and is these days the main driver behind storage expansion; I certainly know my home storage needs expands faster than the vast majority of the servers I admin (yes, there are the we-want-to-simulate-the-atoms-in-the-ocean exceptions, but most business application servers use less storage than you can get in an mp3 player).

It's more, inaccurate, or maybe a result of shallow researching, or at the very least simplified.

Not everyone needs a SAN for storage but using a SAN is a very sound decision for those that need the capabilites it provides. A SAN is not just a buzz word although I do not doubt some people bought them without understanding what they were getting and why.

To avoid missunderstandings, 4 additionals bytes (B) dont seem that much of a price.

oh, and this too
"we present five of the world's biggest SANs:"
notice how everything in TFA clearly says this is not THE 5 BIGGEST SAN's in the world but the 5 largest they have found SO FAR.
I know -- I must be new here, but I'm getting there. I didn't read the whole article, just a few sentences from the first page.

Yes they do.
I am migrating the our support call, issue tracking, and RMA data base to a new server. We take a good number of calls a year and have almost six years of data on the server. The dump file is only 16 megabytes. Most business data is still text and text just doesn't eat up that much space.
For home use doesn't and workstations does NAS make more sense than SAN? I am on a small network so we only use NAS for shared drives.

Go to a law firm and ask them about their document management systems or their litigation support applications. Go to a bank and ask them about their financial records. What about email archives for compliance? Size up the disk space utilization and I think you will see many application servers that are significantly larger in storage than an MP3 player. Point taken, SANs can be used at the desktop level. But I partially wonder why? Wouldn't it be better to synchronize users' data folders with shares on a server that is diskless to the SAN? Why waste all that 'spensive storage just to make workstations diskless? Unless you are using a Compellant SAN or some SAN that is running a deduplication engine on the fly, you're stuck storing an OS install for each workstation.
Besides this, I've always felt that the big advantage of a SAN is the ability to replicate an entire environment to another site in case of disaster. SANs are really utilized to the max in enterprise environments where these features are necessary for successful business operations.
