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.

If your NAS can do iSCSI you could use it to provide a shared block device.
The performance wont be as good as a SAN as the data has to go through the
kernel TCP/IP stack, it can be comparable if you have a iSCSI IP accelerator
board that simulates a hba.

OCFS2 requires a block device (local disk, direct attached,
SAN), so
it's not going to work with a NAS (Samba, NFS, etc)
mount. You can, of
course, share a OCFS2 filesystem using Samba or NFS.

Hi,
Does OCFS require NAS hardware to run or does normal
PC hard disk work?
Thanks,
Pete
