I'm thinking of changing my system from a CC3 system (1 DC, 1 CMIS server) and around 80-90 clients to a Vanilla XP setup using Virtual Servers. Which will be MS 2003 or 2008 server
DC is a 2Ghz dual Xeon with 2GB RAM
CMIS is Xeon with 1GB RAM
(Probably use these as a backup should the new server fail)
The main attraction being able to backup/restore quickly and saving some space in an already cramped server room. Whilst introducing some redundancy. Plus the fact that I find the idea of virtual servers quite exciting at the moment for some reason,
We currently don't even have RAID here. Caused a few issues when the system drive failed on the DC last year.
(Purchased about 6 months before my time in the area and about 32 months before I worked for this establishment.)
Just wondering If anyone else is currently using Virtual Servers and the setup and spec of machines you are running?
I'll probably be up to around 120 clients can't see it going much higher than 150 once we change the system.
Open to comments so please shoot me down in flames if this is a really bad idea. Very early stages here and probably a good 12 months away from doing this. Not commited to anything yet so this is more of a thinking out loud thread.
Yes, we're running everything except our 2 DC's virtually at the moment. Although our imminent new domain will be setup entirely virtually.
We've got a mix of servers running various platforms, all of differing spec's.
2X HP DL350 G5's running Vmware ESX connected to a san. This is seriously under utilised at the moment.
Our main workhorses are a 2 dual core, dual cpu machines with 4-8 gig ram. One running VMware server, the other running microsoft virtual server.
My preference is to use VMware server, although we will be moving to Hyper-V (if it evaluates well) for our 2008 rebuild.
Spec wise, our current machines really are totally adequate. But that hasn't stopped us buying 7 dual xeon dual core 2.66 blades with 4 gig ram for our 2008 rebuild.
p.s. Check the FFS section, i'm about to rant in there about something related to this!
I think DmMcoy has everything on blades and vmware, he can probably tell you more.
We have a test copy of our domain and SIMS server on vmware. We also run a three application servers as vms on a Dell PE860. Properly set up, they're indistinguishable from physical boxes to the end-user.
I will say, get testing now with the free version of VMware Server so x months down the line you have a good working knowledge. The vmware forums are pretty good and so are the docs http://www.vmware.com/support/pubs/
Thanks for the input guys. Did mean to thank you yesterday got carried away playing with VMWare server here and attempting to unjam a printer. (Which is still jammed due to some oik tearing the paper so I can't get at it easily. )
Previously used MS Virtual PC but I can see that VMWare is a little better.
On saying that I couldn't find an option like in VPC where you can drag files from the host mahine straight onto the virtual machine.
Probably have a look at infrastructure next week. Didn't realise you could move servers on the fly before yesterday even more excited now.
You need to be very careful when migrating virtual machines, there are a number of limits with the Microsoft licensing. If you want to avoid buying the number of copies of windows, exchange etc as you might migrate the vm to then you need to stick within the time limits for how often a machine can be moved. Of course I stick to these very carefully despite paying MS thousands every year
