The way I see it is that it's kind of going back to how it was when
hardware was really expensive, so you had to have one server running
multiple apps/roles. Then when hardware got cheaper, esp discs and
memory, all the roles were split up to single machines, at least in my
experience.
I guess I still have a slight fear about running a lot on one machine,
(I know the machines are hardly comparable with then and have redundant
discs/power/nics etc), but I really could do with getting one running as
I said for a lab machine with a citrix box and a few other bits and bobs
like WSUS etc.
Thanks for the info.

We run a couple of low-use Citrix servers (<5 users but a very fussy
app), a PDC and BDC for a legacy NT4 domain, pairs of servers (on
different physical hosts) supporting various in-house developed systems
and a variety of similar machines. I would be happy to run
mission-critical servers on VMWare now that I have more experience and
confidence in it but all of our critcal systems are heavy-use.
On the desktop I use VirtualPC to run all sorts of legacy machines for
software testing and development.

So you're running non mission critical servers, I like the idea
of virtual servers but most of ours have mission critical apps on. I
like the idea for lab machines though!
Cool.

The physical servers have lots of built-in redundancy and I
wouldn't class any of thevirtual servers as enterprise-critical. In the
event of a physical failure I can copy the important ones back from tape
(each server is only a handful of files) to another server (I have a
lower-spec server for development) and bring them back within a few
minutes.

What happens though if a server fails? Haven't you put
all your eggs in a few baskets?

I've got a couple of beefy Quad-Xeon, 12GB RAM machines
running about 30 servers in total.
The main benefits are I can provision low-use servers
without wasting hardware and I can provision them quickly, typically
less than 10 minutes from deciding it's needed to having it available on
the domain for use. They are also easy to backup and move to another
host in the event of a hardware failure, although I've yet to have one.
Running VMWare GSX 3.

Just curious...
How many of you are now using either server
virtualization or storage virtualization (or both)?
If you are using it, what benefits have you
seen?
If not, do you plan to use it anytime soon?
Again, just curious.
TIA
