I have a lab setup that I have been playing with which includes openfiler.
I have a Dell 2950 connected via SCSI to a Dell MD1000 with 14 10k SAS drives ( 1 spare)
A Cisco 3750
And a Dell 2950 running a Server 2008 R2 VM, running IO Meter.
Here are some results.
Settings in IO meter are 32K 100 Read on two drives, and 32K 0 and 0 on the other two.
We’ll discuss design at vbrainstorm.com
