[Ocfs2-users] hardware needed for OCFS

Typically I find folks use 'NAS" to refer to filesystem level sharing 
(NFS, Samba), and SAN for block level (FC, iSCSI).

There are plenty of iSCSI HBAs (I've only used the ones from qlogic), 
however they don't 'simulate' anything - They're just a SCSI adapter 
with an iSCSI backend.
