These problems were all solved once before, with a different SAN technology..... that is optimized for the storage task, incidentally.....

That being said, the Fibre-channel bog-standard two-SPE and dual-attach drives is a good architecture to follow for iSCSI as well for high availability.  Using clustered LVM to back your LUNs can allow this.  Dual attach with SAS is possible, too.

Incidentally, upstream is now doing a storage appliance, for those interested.....
