There is another issue - we are now to the point where buying
replacement drives for some of our servers is getting difficult - or
at least less trivial than it was. Many of our drives are still SCSI
(80 pin SCA) and even if we don't care about capacity (a large drive
will hold a small amount of data without difficulty), SCSI drives are
rapidly being dropped from suppliers inventories. We certainly don't
let a server get retired without salvaging it's drives.
If a drive is still under warranty then it's the supplier's problem
to find a new drive, not ours :)
Unlike a typical PC with cables where it's easy to switch interface
type (or add a controller to mix-n-match), with most server grade
hardware, it's just not practical when the drive interfaces directly
with a backplane so there are no cables.
