Thanks, Jeff. Nice to have someone else saying the same thing! Looks like
we're going for some Dell PowerEdge 2850's, with dual 3GHz processors, 2Gb
RAM, and 4 36Gb 15k drives. Should keep us amused for a little while...
As you say, the plan is to use "simple" devices for storage rather than buy
pricey new servers just to run some drives that will only end up with the
Directors' holiday photographs on :)
Backup is just too scary as it is. We are using a DDS-4 drive, a DLT drive
and an Ultrium at the moment, and I can't tell you how happy I'll be when we
loose the DDS! (And possibly the DLT too)
