the revert to snapshot is a real life saver... can't beat that without some
expensive SAN bits??

I've never been a fan of VMs in the production environment. I have used them
for development a few times, but even then, I prefer a "real world" scenario
for development as well. I've had DC's that were flaky, with the only
variable being VMWare. Dunno, maybe it's just me. Hardware cost are
relatively cheap these days, the form-factor is small, so I don't think VMs
buy you a whole lot. They have their place I suppose, but they are not
something I pursue. Virtual "anything" can never be as good as the real thing
IMO.

Subject: [THIN] VMWare ESX Server
Hi Guys -
Here's the situation. We are about 1/4th of the way through converting
our production data center (full of old, out of warranty Compaq servers) to
IBM BladeCenters running VMWare ESX Server 2.0 (I think... whatever the latest
version is). We use Platespin to convert the physical server to the VMWare
image and move it over to the Blade it's going to live on. Right now, we have
an average 5 servers per blade planned, and several have already moved over,
because the hardware failed that they were on. However, some of the
application folks are uncomfortable with this solution, not so much the Blade
technology, as the VM technology. Needless to say, we're already experiencing
failures, and stuff not running right - performance issues, network issues,
etc. (Can you believe that they are going to run our Root Domain Controllers
on this?) I have already experienced a drag on one of my Citrix servers that
moved to virtual space, and can't fix it up.
So what I would like to do before things get too much more hairy, is to
try to find out what the success rate of running something like this in
production, and if there are a lot of people out there doing this. Feel free
to share with me any nightmare stories too! :)
Thanks much!
