Title: Re: [PERFORM] Poor performance on HP Package Cluster
Sure – I posted the excel spreadsheet to the list right after my message, but I think it blocks attachments. I’ll send it to you now privately.
I recommend switching to software RAID 10 or 5 using simple SCSI U320 adapter(s) from LSI
Hi !
Sorry, for my late answer. I was unavailable for a few days...
Yes, I'm using the build-in HP Smart Array Controller. Both, the internal disks, and the external storrage are using the controller.
Can you send me your test results? I'm interested in it.
I've done some testing now. I've

I've previously posted comprehensive results using the 5i and 6xxx serie
Do you have any sources for that information? I am running dual
SmartArray 6402's in my DL585 and haven't noticed anything poor about
their performance.

Are you using the built-in HP SmartArray RAID/SCSI controllers? If so, that
could be your problem, they are known to have terrible and variable
performance with Linux.
The only good fix is to add a simple SCSI controller to your system (HP
sells them) and stay away from hardware RAID.

Your HD raw IO rate seems fine, so the problem is not likely to be
with the HDs.
That consistent ~10x increase in how long it takes to do an import or
a select is noteworthy.
This "smells" like an interconnect problem. Was the Celeron locally
connected to the HDs while the new Xeons are net
Hi!
I've set up a Package Cluster ( Fail-Over Cluster ) on our two HP DL380
G4 with MSA Storrage G2.( Xeon 3,4Ghz, 6GB Ram, 2x [EMAIL PROTECTED] Raid1)
The system is running under Suse Linux Enterprise Server.
My problem is, that the performance is very low. On our old Server
