We are about to purchase (end of life) EVA 5000 with 8TB raw disk space for a very reasonable price. Even though the EVA 5000 is end of life, but support will still exist for another 3-5 years as I been told by HP. However, we're facing performance issue with the MSA 1500 SAN evironment. From what I've read, the EVA SAN is the way to go. Does anyone here know where I can find some comparision docs on the MSA stack against the EVA?? I just need some facts that the EVA will provide the double or triple what MSA SAN can give you.
I need to make the management team feel more warm & cozy.
Thank you in advance.
Jorge

Re: MSA 1500 vs. EVA 5000 SAN
How many servers and how many HBAs/server do you have? If you're percieving a 'performance issue' in the MSA configuration you describe, I'd suspect something on the server end first.

Re: MSA 1500 vs. EVA 5000 SAN
I'd work from your hosts to their HBAs, to the SAN switches to the MSA controllers to try to find the bottleneck. Sounds like you are experiencing numerous retries, path conflicts, zoning conflicts, or physical hardware issues.
That said, the EVA is a sterling piece of hardware, so you would not be disappointed to have one. But I'd wager it is throwing hardware at what is probably not the problem.

Re: MSA 1500 vs. EVA 5000 SAN
There are no other OSes on this Fiber switch. I need to look more into zoning per server. and per lun.
Thanks,
Jorge

Re: MSA 1500 vs. EVA 5000 SAN
Simply put, the default qlogic hba driver (qla2300, in our case) did not properly support the storage array. We had to back out the default driver, and replace it with the HP supplied driver from their linux platform kit.
My notes, albeit cryptic and probably imcomplete are these:
# lspci
... snip
01:06.0 Fibre Channel: QLogic Corp. QLA2312 Fibre Channel Adapter (rev 02)
... snip
/* this shows you the qlogic hba */
/* now install the hp supplied linux platform kit. This should delete the current driver and replace it with the HP driver */
# cd /opt/hp/hp_fibreutils
/* you'll see a bunch of useful utilities that can verify your installation and also probe for attached luns */

Re: MSA 1500 vs. EVA 5000 SAN
As much I would like to see you spend the money.
If you like, I can take a quick look at your system. You will need to capture some data for me. Can you attach a cli cable to the 1500 and issue the following cmds.
>start perf
This will start the performance counters on the MSA controller. There will be very minimal controller performance impact.
Let this run during the busiest part of the day.
Then issue the following commands,
>show tech_support
>show perf
>show perf logical
>show perf physical
Cycle through the following commands a couple of times. Each take a snapshot at that moment.
>show taskstats
>show cacheinfo
>stop perf
Then attach the results.

Re: MSA 1500 vs. EVA 5000 SAN
here's the result after I ran "lspci" command;
40:1e.0 Host bridge: Hewlett-Packard Company zx1 Local Bus Adapter (rev 32)
80:02.0 Fibre Channel: QLogic Corp. QLA2312 Fibre Channel Adapter (rev 03)
80:02.1 Fibre Channel: QLogic Corp. QLA2312 Fibre Channel Adapter (rev 03)
80:1e.0 Host bridge: Hewlett-Packard Company zx1 Local Bus Adapter (rev 32)
a0:1e.0 Host bridge: Hewlett-Packard Company zx1 Local Bus Adapter (rev 32)
As you can see, the Qlogic (QLA2312) default driver was used on this server. Do we have something here?
Thanks for your time.

Re: MSA 1500 vs. EVA 5000 SAN
I will capture the info of my MSA 1500 sometime tomorrow and post it here for you to review. I really appreciate your help.
Thank you in advance.
