ML350 G6 too too slow

hello,

I setup a ML350 G6 12GB Ram 4x146GB SAS Drives with two volumes with RAID 5.

The problem is the system speed, when you got the login screen and write down name and user it takes about 10 minutes to have the desktop available.

I run a disk benchmark test and got results below the 10MB/s both reading and writing.

I used the last firmware and flash for the array controller (from yesterday) and activate the cache with the array setup utility. The controller is as I bought it, without battery and no memory upgrade.

Somebody has any idea about what else could I do.

Thank you

Re: ML350 G6 too too slow

What about any Spyware/Malware/Antivirus software working in background?

Did you test the same thing in SafeMode?

If the server works well in Safemode, may be you have to check or remove some unwanted software which gets loaded during startup.

Hope this helps.

Hi,

Yes I tried to boot first leaving just the hp services and no programs at all from start menu or registry "run". It was a little faster but not usable. After that I enabled the services from microsoft and the speed was almost the same.

We are now without any antivirus/firewall software.

By the way, the CPU usage is not so high, commit charge is at 36%. I will attach an image with system information. I can see a lot of memory peaks, I don't think this must be right

Re: ML350 G6 too too slow

RAID 5 can do that. You never place the OS in RAID 5. Use RAID 1 or RAID 10 for the OS. Swap/Paging should be RAID 1 or 10 only. The 10 MB/s is caused by parity writes. I would consider backing up and redoing the server RAID configuration. I never use RAID 5 on production servers that need write performance. My servers and SAN use RAID 1 and RAID 10 only. RAID 5 is too slow for writes.

Thank you Michael,

it's posible you are right, I could see it before, but sometimes trees can't let you see the raid 5

Re: ML350 G6 too too slow

While I agree that RAID 5 is slower because of the striping... it's not THIS slow. Please generate and ADU report and attach it here.

Cheers!

OK, I will download the lattest service pack for proliants and run de ADU but it will take one or two days

I saw 10 MB/s per drive performance on RAID 5 on IOPS tests using IOMeter to similar SQL traffic 75% writes / 25% reads. Did you check your controller to verify battery cache is enabled and caching on the controller is enabled.
