EVA Performance

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.

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.
