recommendation on platform?
Trevor,
I got EXCELLENT results builing a SAN from FOSS using:
OS: Centos
Hardware: 2X storage servers, with 12x2TB 3.5 SATA drives. LSI MegaRAID
with CacheCade Pro, with 240 GB Intel 520 SSDs configured to do SSD
caching (alternately, look at FlashCache from Facebook)
intel 10GB dual port nics, one port for crossover, on port for up link
to storage network
DRBD for real time block replication to active-active
Pacemaker+corosync for HA Resource management
tgtd for iSCSI target
If you want file backed storage, XFS is a very good filesystem on Linux now.
Pacemaker+Corosync can be difficult to grok at the beginning, but that
setup gave me a VERY high performance SAN. The downside is it is
entirely managed by CLI, no UI whatsoever.
