Looking for some advice regarding virtualization please. Not something I've had to think about before :)
Need to build a new server to host some VMs for use by our testers.
Currently using Hyper-V on a fairly standard i7 workstation and its performance sucks. Its running 8 Windows 7/8.1/2008/7em VMs, with usually only 3 or 4 of them in use at any one time. Its got 32Gb of RAM and a decent i7 but I can see the choke point is disk response time, its terrible and causing all the VMs to crawl along.
Thinking about replacing it with a HP Proliant DL 320 or DL380, but wondering about what specs it really needs.
For say 8 VMs running at once, giving them 4Gb of RAM each and at least two CPU cores, what kind of CPU or CPUs should I be buying? Xeons any better then i7s?
I obviously want a decent RAID controller, any recommendations here on a real fast one to help reduce any disk access issues?
Is it worth going for one that can support RAID5 instead of RAID1?
and finally, in my own experience I've never seen anyone use Hyper-V outside of Microsoft training courses, VMware seems to be the industry standard. Are we wasting our time with Hyper-V as its reported to be slower then VMware? Should we bite the bullet and switch to VMware for better performance?
