The show hasn't even officially opened yet, and I just got a brief but enlightening tour of the StorCloud infrastructure. 650TB of storage from a dozen vendors, linked through SCInet via 10G, 1G, Infiniband, and FC to various clusters elsewhere on the show floor. Mostly driven by a mess of Cisco's biggest iron, it's quite impressive.
Some vendors are mapping luns directly via FC or iSCSI, some are leveraging NFS, but all that storage is live and available where it's needed. Some of the challenge events are using it, as are some of the other demos on the floor.
Very, very cool.
