I had a Inkedin discussion with Robert Seal of iSam Blue who seemed knowledgeable on this topic. You might give him a call:
There seems to be other options besides EMC and IBM but it sounds like you'd need to connect IBM i to VIOS, then VIOS to your SAN solution.

Subject: SAN Vendor support for IBM i?
Does anyone know of any SAN's that are compatible with IBM i other than from EMC or IBM themselves? It seems we only have two vendor choices on this front whereas our Windows boxes has an incredibly larger vendor selection.
I've looked at Xiotech, NetApp, Equilogic (dell), Compellent (dell), and HP and none of those vendors seem to support the iSeries. They all have SAN's that work with Unix/Windows/x86 boxes but not the iSeries. Additionally cost is a factor, for the price of TWO 8TB san's from the manufacturers that do NOT have iSeries support we cannot even get ONE from EMC or IBM.
Kinda disappointing so far, so I'm hoping someone can tell me of an economical SAN that is compatible with the IBM i that have all the bells and whistles that we are use to from the big guys in the x86 world (geolocated site failover, blocklevel replication and restore, automatic management of files by moving frequently access to faster drives and lower access data to slow drives, etc).
