LSI 9260 vs. AMD SB850

[F@32]

those are some nice numbers, however, the fact that you cant boot a soft array just totally ruins it for me. i just have no use for a non-boot array personally.

Hey CT, sorry if I was not clear: those numbers are from SB850 RAID which is bootable. I only did pass through mode once to see if there was anything funny going on.

tbh that cpu usage you are showing with that is shocking! wow 78 percent! ive never seen ICH kick off utilization like that with a soft array, however, i havent toyed with it too much....but that number seems abnormally high to me.

Yep, I'm glad AMD drivers utilize more than one core even with 1 worker.

does your mobo have the NF200? seems like some motherboards and the nf200 do not mix AT ALL with the 9260...like kryptonite on the classified e759

Nope, that's a 890GX/SB850 mobo.

I had a shot at the 9260 on my Asus CHIV, it didn't work as my boot drive was configured for RAID and and as soon as I installed the 9260 it just wouldn't let me select my boot drive again.
All that was left was the 9260 and I can't reconfigure the drives right now.

Will give it a go at some later point in time.

Appreciate your help. I would like to see someone else's AMD+LSI numbers. I experience problem installing Win7 on LSI array. Every other or so re-boot it drops one or both drives. No problems otherwise... Right now I'm not too happy with LSI 4K IOPS without FP. 40% CPU utilization with AMD QD16 and 50K IOPS vs 6% utilization with LSI and 35K IOPS... For $350 card I would have expected it to whipe the floor with SB850 even with 2R0, but it seems another $150 needed to match and beat it. That's $500 vs something that's already there. This build is for gaming and 24/7 use. I don't think I will see benefits going 4R0, bottleneck is be back on CPU anyway.

Not really, but I am quite happy to see AMD's drivers actuall use multiple cores! LSI 9211 would only use ONE core on my C2Q build, and it was obvious it is exactly CPU limited. (it gave awesome numbers though :P)
I think that also Intel's ICHxR will not use more than one core. Windows "RAID" won't use a full core even on a large RAID5, I don't know why (neither will it use it for EFS!). I am at a loss why.

Yeah, 9211 is a darling but LSI shows no love with gimped firmware and drivers. I could imagine with proper multi-core support and above 128K sequential scaling it could fly... I'm still thinking about picking up IBM M1015 re-badged LSI 9240 for the heck of it... Funny thing is, it seems 9240 is not gimped like 9211. And it's only $20 or so more expensive.

To achieve ~100' IOPS on the SB850 I had to use 4 or 6 workers (iometer), CPU utilization >90%
Jasper Forest might change raid-5 performance on the Intel platform

Nice, was it in 4R0 SF?
