Thanks for your response. If I'm reading what you said correctly ANY
iSCSI device would be compatible with GFS? I apologize if this is
common knowledge but I've been having problems tracking down some of
this info.

I'm actually surprised at how little information I've been able to
find on the DS300. It seems to be a very good product with SCSI drives
that is comparable in price to something similar with SATA drives.
Maybe people just don't consider Big Blue for these things?
