EVA Performance
Does anyone have any experience of getting statistics showing throughtput to an EVA unit.
We have 2 X EVA 5000s and 2 x EVA 4000s with LUNS presented to a mixture of hp-ux and Windows servers. I would like to plot the throughput to each to show where we have most I/O capacity.
Thanks

Re: EVA Performance
In this topic, you can see some experiences I had and some mistakes that I made.
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=987326
There you will see my tests results. Also you should be familiar with the use of evaperf. Some quick tips:
List arrays:
============
evaperf ls
Translations
============
To translate WWID to names, you must create a file called fnames.conf in the evaperf directory, and should contain:
WWID NAME
Like this:
5000-1EE2-5022-4233 eva1
Also for vdisks.
Overview
========
Total throughput:
evaperf as -cont 10
For one array only:
evaperf as -sz eva1 -cont 10
Controller status
=================
evaperf cs -cont 10
Host ports
==========
evaperf hps -cont 10
Virtual disks
==============
evaperf vd
evaperf vd -sz evaA
Host connections
=================
evaperf hc

Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Re: EVA Performance
Thanks for this Ivan. We are investigating the use of Evaperf now - thanks for the tips.
