What level of raid do you recommend?

We run a farm of Dual P3/800 machines with 2GB RAM each, running a
fairly
intensive patient admin app. Each server handles up to 40 users
concurrently
and we've yet to meet a performance problem. Your servers should be
fine.
I'd still go for a pair if I were you, for redundancy. Even a single
server
should manage what you want although IE isn't the most thin-client
friendly
app.

Looking for some feedback here. I worked a lot with load balanced farms
and
NFuse in the past with Winframe and Metaframe 1.8, but I haven't used
Citrix/TS in about 2 years so I'm kinda rusty. XP wasn't even available
when I was managing my Citrix servers so I'm clueless when it comes to
XP.
That being said, be nice to me, haha.

I'm currently considering updating one of our computer labs (in the high
school) which has older PII machines. The original thought was to buy
brand
new PCs but I'm starting to reconsider and thinking about going Citrix
(or
maybe just terminal services) and re-using the old PCs. The older PII
machines should be enough to work as thin clients. The PCs are mainly
used
to surf the internet (IE), Office XP (mainly Word, Publisher, Power
Point),
a speech program, and a CAD program. =20
=20
I was tentatively looking at using Citrix XP with load balancing for the
lab. (2) IBM x345 servers with dual 2GHz processors, 1GB memory, and a
single 36GB drive. I've always been under the theory that when you use
Citrix load balancing, it's more cost effective to NOT stock your
servers
with redundant power supplies, redundant drives, redundant NICs, etc.
since
the redundancy is taken care of via load balancing instead of at the
server
level. This keeps my cost of hardware cheaper, which saves me money to
afford the load balancing piece for Citrix or software assurance, etc.
=20
My question is whether or not the proposed server setup listed above
would
be adequate for this lab. All 30 PCs would be used at the same time, so
I
could POSSIBLY have 30 users using internet explorer at the same time so
I
need my servers capable of handling this load. I was originally
thinking
having (2) IBM x345 servers with a single processor, but I'm leaning
towards
dual processors. I'm looking for feedback from people on whether my
server
config would be adequate or whether I need more servers/hardware.=20
=20
If memory serves me correctly, and it probably doesn't, I thought a dual
processor PIII Xeon processor server with a lot of memory could easily
handle 25 users. If that's true, then my configuration with two servers
would be overkill. =20
=20
Thoughts? Thanks.
