I have configured HYPER-V on this server. Right now i have added few virtual machine on this HYPER-V server.
Configuration of all VM are as follows.
Windows server 2003 Standard Edition.
max 10GB space required for each VM.
1]No. of logical processor - 1
2]Virtual Machine Reserve(%) - 0
3]% of total system resources - 0
4]Virtual Machine Limit(%)- 100
5]% of total system resources - 4
When I run more than 10VM on my single SATA II 7200RPM. Applications running slow on each VM. Each VM using just 60% max of 1 logical processor & max 50% ram utilization. Still application running slow on each VM when I run more than 10VM. I have concluded that it is cause of high IOPS from each VM to my single SATA II. Will single SSD is enough to run 20VMs? Or do I need 5 SSD in RAID?
