As a fun project, I've managed to get 16 SCSI drives from eBay (all
working, tested myself) of 23 GB each. I am planning on making a file
server out of these drives. I've already got two SCSI controllers for the
drives (as well as a SCSI CDROM and two other SCSI drives for other uses in
the server), and I'm curious if anyone has done anything similar before.
The toughest part I've had so far is finding a way to power the drives,
thankfully they will draw a peak of 25.6A on the +12V and 16A on the +5V,
and I found a supply that will give 36A on the +12 and 29A on the +5. So
power is good. I'm working on an enclosure to house them, and I've got
long enough cabling and external hookups for all the drives to connect to
and stuff.

Basically, has anyone undergone something this massive (and pointless)
before, and if so, what pitfalls should I watch for?

Necessity is the Mother of invention.

I'd tell you a secret, but it wouldn't be a secret anymore.

damn thing will sound like a jet airliner taking off when those babies all
spin up. Better stand back or get sucked into the gravity well.

Thor:

Have you ever thought about setting up a for-pay support system? I have
some clients/friends/colleagues who might be willing to pay you for your
expertise, but they are not going to post in a newsgroup. (I would have
sent you this message privately, but you don't have a valid email
address. If you have a throw away Yahoo or Hotmail address, send it to
me privately and I'll tell you my thoughts.

It's not as outlandish as you might think. I've got a closet full of
old SciNet SCSI CD-ROM servers that each contain 7 SCSI drives.

I personally can not answer for Thor on this question, but one must realize
one thing about this newsgroup and it's participants:
Most (if not all of us) don't do this with the hope of being paid. We do
this because it is a talent we have for some reason that not everyone does,
and if we can take 30 minutes of our day to give out free advice and help,
we are giving back to the community. I can't say that Thor wouldn't take
your offer, but I can say I would be very surprised if he did.

I suspect that many of us already do support work for pay. I know that I
do-or did. (When they hired a new support tech they moved me to mostly
programming.) We (or at least I) participate here not only to 'give
back' as you mentioned but also to learn & expand my skills.

IMO the hardest part about support is 'remote' support. I'm lucky in
that most of my paid support duties are within this building-if I can't
understand the user's explanation of what's going on then I can get off
my lazy butt & go over to see for myself. In my side job (self-employed
support) that often isn't possible so I need to keep my communication
skills sharp-diagnosing problems from inadequate descriptions,
communicating solutions to people who have only the slightest idea what
I'm telling them to do, etc. Participating here-both what I offer & what
I see from others-helps me with that.

So personally, I participate here for two reasons-gratitude for the help
I've received, both here & elsewhere, in the past & self-benefit for
what I'm receiving now.

Thanks.

Thanks for the offer, but I must decline. I already have plenty on my
business plate to handle.

Never tried this before. I imagine that the noise will be pretty bad. But
do keep us updated on how it turns out.
