You will have better luck if you want to use MPI-IO and the userspace pvfs utlities. PVFS will definitely play well with the SAN, but you might have to re-think your toplogy a bit. Start with the SAN file system. Format it however you like. There's no 'mkfs.pvfs' for example: PVFS sits on top of an existing linux file system. You'll need linux servers to attach to the SAN. It's those linux servers your clients will talk to. I don't know of too many people using Xsans and PVFS: I fully expect it to work, but we may not be able to offer much in the way of tuning or configuration hints. However, feel free to carry out a discussion of those aspects on this list, as the resulting conversation should prove quite helpful for anybody following in your footsteps.
