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

<pre wrap=""> 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.
