Mike, that's some pretty impressive results for the 2540

I will avoid iSCSI because i've read in various posts that the latency is
considerable, particularly for an intensive db (and this one is expected to
grow to 200G over the next 12 months).

What i need to consider is that our WAN is not strong enough to support
multi-site mirroring. I will be having site-to-site db replication, but that
is not prone to latency and WAN issues as the mirroring would be.

Therefore, of utmost importance is the reliability of a single array. You
mentioned a lot and favoured the 2540. Can you please give some info on your
experience of the 6140?

NB - The 2540 fully populated with 300G 15krpm disks costs just a bit more
than the 6140 with 150G disks, while giving about 0.6TB more space per
array.
