Question
Virtual machine performance on software RAID 0 (stripe) in Windows
Hi,
I would like to know what people's experiences have been with running VM's off software raid 0 volumes in Windows XP or Windows 2003.
Specifically I am running a classroom of PC's and we use VM's every day. We need to upgrade them. I am looking at options. One option is to upgrade disk, another is to replace the whole box.
Current spec:
Pentium 4 2.8GHz, Prescott
2GB RAM
80GB HDD SATA
Proposed upgrade:
Add 160GB HDD, split into two partitions, one for OS, then make a stripe over 160GB and 80GB drives.
Run virtual machines off stripe.
I don't really care what free VM software we use, but we are running on top of Windows 2003.
e.g VMWare Player, VMWare Server, Virtual PC 2007, Virtual Server are all options.
OS we run in VM include: Knoppix, Ubuntu, XP, 98, 2003, Vista, Server 2008.
So my question is:
What kind of performance increase am I likely to see running VM's off a software stripe volume in Windows 2003?
Example answer: Your VM's will boot about 30% faster. Overall responsiveness will improve. Running several VM's concurrently will be noticibly faster and smoother. Vista on stripe will run about as fast as XP on no stripe.
