Our AIO 600 configuration is 5 x 7.2k SATA drives in RAID 5, 2 GB RAM, Windows 2003.
At network transfer speeds of > 200 Mbps (receive/write), the AIO performance is considerably reduced. Console user's experience is sluggish. VMWare Guest Machines with iSCSI storage provided by the AIO suffer. At > 400 Mbps, the AIO becomes unusable from a console and iSCSI perspective. This occurs with NFS and CIFS shares.
We observe that System Cache during these periods uses 3/4 of the available RAM.
Is it possible that our drives are a bottleneck, and that the AIO cannot write as fast as the NIC(s) receive, causing the cache to use up RAM, eventually leading to performance degradation?
Are there papers that explain performance expectation of an AIO600 in our configuration? We have DL380s with attached MSAs that move data at similar speeds without the same problems.
Thanks in advance,
Andrew

Re: AIO 600 performance
they are very slow , use 15K drivers for VMWare and other IOPS demanding application like Sql and Exchange

Re: AIO 600 performance
you can check with perfmon if the disks are the problem. You shouldn't have more then 10 - 15 IOs in the disk queue, and the command response time should not exceed 30ms. By the way: RAID 5 is not optimal for your enviroment, you should use RAID 1+0 instead.
Best regards,
Patrick

Re: AIO 600 performance
Eli - interestingly, I hadn't noticed this before, our disk drivers are listed as "HP LOGICAL VOLUME SCSI Disk Device". This system was built with the shipped with CD. Are these the wrong drivers?
Patrick - wow! If we're supposed to be at 10-15 IOs and response time under 30ms, the disks are maybe having trouble. Our %disk time avg during a medium utilizatin period (50-70 Mbps) is 112 (I assume they're described in milliseconds in perfmon? %Disk Write Time avg is 54. Avg Disk Read Queue Length is 1.7, however, the it is graphed as if it is in seconds rather than miliseconds. I'm not sure how to interpret that number. Same for Avg Write queue at 2.34.
Robert - I will get back to you with the firmware info.
Thanks to all.

Re: AIO 600 performance
We aren't committed to disk spanning, in fact I wish I hadn't done it to begin with, however moving off 1+ TB to break the span and start over with basic disks would be a large undertaking -- especially since our AIO is performing so poorly.
I'm on with HP support now to get a case number. Will post it when I get it.
