Va7100 - bottleneck
I run with L2000 11.0, 3 CPU's 4.5 of memory and we think the array va7100 is our bottleneck.
Could you give me a clue to increase the performance of disks
I don't have glance on this machine...

Re: Va7100 - bottleneck
* are you on the current Firmware (not shure but should be something like HP18)
* does the box run in Raid 1/0 or Autoraid ?
I prefer 1/0.
* use more Disks -> stripe over more Disks or have more 1/0 Space in Autoraid Mode.
* is application "well behaving" ?

Re: Va7100 - bottleneck
In general, in your "sar" output, your "wio" should remain < 10% if your disk performance is good. If it's > 10%, you would benefit from some tuning.
With the VA, be sure that your primary path (in LVM) is Controller-1 on the VA. This will give the best performance.
That's about it for the general stuff... tell us more about your environment, and we can probably make more suggestions.
Good luck,
Vince

Re: Va7100 - bottleneck
If your not on HP18, then get HP to upgrade your array.
With HP18, set Prefetch Enabled, and Normal Resiliency - these are KEY settings!
After you've tried the above, and you still have poor performance then (in this order);
- Add more disks until you're in RAID 1+0.
- If it's a single controller configuration, consider adding the second controller (this enables write cache)
- If these don't help and this array is full, consider adding more arrays. If you can't afford that, conside removing cpus from the L2000.
