All,

I am looking for a way to replicate i/o to a disk array that simulates a
current symmetrix dmx in our environment.

The aim of this is to enable me to take a look at the way that SRDF/A would
behave if I gave it a "real" workload, of differing i/o read and write sizes
(spread accross 2k, 4k, 8k, 16k and different application profiles also

Has anyone got a test plan / tool set that they use for this type of
investifation?

The end hame is to have async replication  between a production and DR site
of around 500km.

Many thanks in advance,

Jo.

Try IOmeter
an the attached conf file
test with and without SRDF/A option enabled

IOmeter is at:
http://sourceforge.net/projects/iometer/

if you plan to test only the link, you can make a ramdisk on the target
site.

iometer.icf
put this in an file:

Many thanks for this Voni - problem is that this can only be run on a single
machine at a single time - I am really looking to simulate multi-node
interaction with the symmetrix, ie 50 odd computers submitting i/o to
varying FA's at the same time.

Any thoughts around this, or am I purely looking at setting up a whole heap
of machines to do this?

Many thanks,

Jo

Hi jOwLeY

Please read the manual:

http://www.iometer.org/

http://cvs.sourceforge.net/viewcvs....br />
rev=HEAD

You can have multiple Managers on multiple Host across multiple Platforms at
the same time or step by step

Only the GUI is Windows based.
