if you mean with XP HP's XP256 or comparable, i found the following:

Setup
HP lpr1000 1U server.
QLogic FCal Card
Brocade FCAL switches
XP256 with 1,5 TByte in ~7 Gig slices.

the problems which prohibited us from using this setup in a production 
environment:
Linux could not scan all the LUNS and SCSI ID's without kernel modification.

The mapping from LDEVs to SCSI-ID/LUN could not be performed in a 
reliabel way on the linux box. Since the XP256 was shared between 
different servers (Sun Solaris) this was the showstopper. We could never 
be certain which ID/LUN corresponds to which LDEV (7 GByte Slice).
