Hello Nick, While an iSCSI SAN will not have any problem allowing multiple hosts to connect to the same volume, what it doesn't do is protect you from the resultant corruption. Each host will believe it owns that volume exclusively. Writes from one host won't be seen by the other host. They will eventually overwrite blocks written by the other and corrupt the file allocation table. The solution is to use a global or clustering fllesystem that will manage the cache and writes. Filesystems like GFS, Polyserve, IBRIX, Tivoli, etc... GFS is open source, the others are commercial filesystems that run many thousands of dollars.
