Disk Statistics

[Cabby]

We have installed a tool that gathers some SAN statistics for us. I am trying to make sure I interpret them correctly. I haven't been able to find a document that indicates acceptable baselines for the following:

Read IOPS, Write IOPS, Total IOPS, Read mbps, Write mbps, Total mbps

If some one could poiunt me to a doc or tell me the numbers, I would appreciate it.

Thank you.

IO meter is a good place to start.

Plus there is an Official Performance Thread started by Christian Z (and another, but don't remember who) in this same thread that other people have posted similar benchmarks.

This is also a good read: http://www.yellow-bricks.com/2009/12/23/iops/

As I said, I already have a tool installed so I really don't need another one like IOMeter. The YellowBricks article didn't address waht I was looking for nor did the white paper mentioned in it since we are not deploying VMView. I will look for the Official Performance Thread.

Hi ,

Its depends on your Hardware types such as HBA, SAN model, type of Disks SAS, FC, SATA etc.. Please provide your SAN vendor and your disk types to know exact thresholds. Cheers!

It's really unanswered but I'm not getting any responses.
