Option 1) 2 servers each having 2.0TB raid disk with SAS
drives, 2GB ram and standard other features.
If going down this road, why not look into getting one of
those fancy new storage enclosures where the RAID is built
into the enclosure and can allow 2 servers to simultaneously
access the arrays with full battery backed write-back cache?
What is available for Linux in this department?
I'm testing out an MD3000 from Dell. It can allow 4 hosts with
single 4x serial paths, or 2 hosts with redundant 4x serial
and can chain up to 2 MD1000s off it for up to 45 spindles.
It was 2 RAID controllers in 2 EMMs with 512MB BBU write-back
that is synchronized between them which act as redundant RAID
controllers. Ships with 4 plain-jane 2 path SAS controllers
for host systems.
Downside, right now, it currently only supports SAS drives,
they hope to have a SAS/SATA firmware update maybe by year-end.
Binary drivers from Dell?
