I've bought two SAN devices in the past couple years, both run
Debian and both are tier 1 enterprise storage arrays. Of course
you wouldn't know they ran Debian or linux unless you tried
to telnet to them on port 22 and saw the SSH banner.

My active-active NAS head units runs CentOS 4.4 on IBM hardware
(back end disk storage provided by above array)

If you use a purpose-built appliance OS it should be pretty
comparable, e.g. openfiler or freenas(bsd based?) to something
like a Thecus. I used openfiler about 1.5 years ago mostly for
iSCSI and it worked ok, at one point had 4 shelves of HP MSA
SCSI disk drives attached to it each connected to dedicated
RAID cards on an older HP DL585.
I'm looking to get a Thecus N770 myself pretty soon, mainly for
the smaller integrated form factor with many drive bays.
