About redundancy: we have distributed filesystem (IBM GPFS), on several nodes. Each node have it's own disks directly attachet to it - there is no shared storage. So we use GPFS replication to store two replicas of all data. Disks of virtual machines is actually a files on GPFS. So, to export disk of one virtual machine, we need to do it on at least two GPFS nodes from both GPFS failure groups.
Sounds interesting, so you are using also GPFS from the client side and have GPFS work in its SAN mode?
Now i have one more question about iSER: I plan to use Centos-5.5 as GPFS nodes (and iSER target) OS. Latest OFED not supports iSER on kernels older 2.6.30, so i need to use a distribution IB stack instead latest OFED. Is that a good idea, or maybe i need to look at another operating system distribution for iSER target?
We're going to add iser initiator support for ofed soon, for the time being, yes, use the RHEL provided ib stack
