We still have a couple Sparcs in service, doing odd jobs. Mainly haven't
gotten around to replacing them, however I will probably keep at least 1
running indefinitely for software portability testing.
I think with the cost of PC hardware today that a brand new device is
less trouble for a production server and faster as well. You can get
a clone rack mount server built on an Intel desktop motherboard with
mirrored SATA 200GB disks for a bit under $1000 now that will kick the
stuffing out of just about everything older that you can lay your hands
on, and be more reliable.
Where I still use older gear is for servers that there's -no- money
budgeted for, and that there's a vested interest in keeping -off-
the radar scope of upper management for political reasons. For example
that older 300Mhz P2 server decomissioned a few years ago makes a great
platform to run Nessus on, and the last thing I want is a discussion
among the upper managers who don't know any better of the merits of
whether or not we should be attempting to break into our own desktops.
It's much better to find the insecure desktop then go to the upper
managers and tell them that you caught employee X who keeps bringing
in his personal laptop and docking it to the network, and who never
updates it because way back in 1892 an update broke his 2,000 year old
shareware wigit he downloaded for free, and now he never updates,
that his precious toy has 10 security holes in it. You get what I mean.
In any organization there's a need for "stealth" servers that
aren't publically acknowledged by the IT group as existing, but
nevertheless have key tasks, if not politically controversial ones,
