Hello List,
Can anyone recommend some sites regarding building high-availability storage networks using centos (or the upstream providers brand name)? I need to have approx 2-3 tb of storage available via iscsi and smb, but worry about having it all on a single server. Most of the HA articles I'm reading deal with application high availability, but not storage.
Check out openfiler?

For me I would just buy a real storage array, better reliability generally. Though entry level pricing is around $20k.

Hi Nate,
In some countries those storage arrays are about 3 more expensive, so it's cheaper to build it yourself with PC / server components. I'm actually interested in such a setup as well, and would like to cluster 2x machines to give a network RAID setup. What would you recommend using? The idea is to serve to servers which will be clustered as well, hosting web hosting Virtual Private Servers.
You could use DRBD, if you trust it. AFAIK, Parallels more-or-less supports this. http://wiki.openvz.org/HA_cluster_with_DRBD_and_Heartbeat
