Server2008 R2 - slow hdd speed test on C drive(OS) Virtual machine
Posted on 2014-02-24
I've got a small issue I'd like advice on:
Server 2008 R2 64bit Virtual machine, running on ESXi 5.5
3 vdisks make up the VM.
c drive - 150GB
d drive - 150GB
e drive - 150 GB
Storage is HP MSA P2000 G3
Qlogic SANBOX 5800
Virtual machine vdisks located on 600GB SAS drives 15K making up a 1.8TB volume.
My issue is that in the c drive I get 200Mbps speeds
On the d and e drive I get 1.5Gbps speeds
Why slower on the c drive, all drives using same Volume 15K SAS drives.
