World's Five Biggest SANs

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."

Bad way of putting it.

14Pb for 170k employees isn't so much - 83 gigabytes per person. Sorry, this is completely naive. It's a misunderstanding of what an average is.

Each employee is NOT getting 83Gb of space on the SAN. They might get a few Gb for email. That space is used to store accounts, general business stuff, personal information, credit reports, market information, simulations etc primarily for data mining. Then of course it's replicated to several locations.
