Hello all.
We start to heavly use VmWare virtualisation and run on unknown perfomance problems on guests.
What we have:
Virtual Center on IBM-3550 Windows 2003 with
MSSQL Express.
3 ESXi Nodes on IBM-3650 with 48Gb RAM on each. With Qlogic 2440 fiber controlleron each.
Fiber swithc: HP StorageWorks Base
SAN switch 4/8 (ext.16x4GB ports)
DAS: Proware SB-3163-F4A3, 16xSATA HDD
Seagate 1Tb with 4хRAID-5 and 2хRAID-10.
We create 75 virtual machines mostly with FreeBSD and Windows OS. And abount 15 Linux VM.
About 10 VM have 4 virtual CPU and 4 VM have a 6Gb RAM. We use 32bit and 64bit OS.
Mostly we use virtual env for test purposes - about 60% of VM is stais IDLE for all time.
What we got:
Time after time we have really bad perfomance issues. VM start to work very slow all operation take up to 5x more time.
I try to monitoring VM at this time - but VC not show any perfomance bottle necks.
How can we find what caused whis? Is were is a any "best practies"?
Or may be we just doing all wrong at some point?
