Here's the xlsx file of your numbers and the graphs. Attachment 103736
Later, after i've done steve's numbers, i'll make some comparative graphs to the data i already have from other setups running the 0,5-64KB QD1-128 exp2 v4 config.
I may make a new thread for that comparative stuff.
GullLars
Do create a new thread!
Tiltevros,
Now, how about a small tweakers/getting started guide for the 9211 :)
the graphs over the C300 thread linked 2 posts ago show the about the same scaling for 4-8QD at 4KB and at 64KB, unless anyone care for another few tens of MBps or even a 100 when the difference between the 9260 and the 9211 is about 200MBps for the 9211 at irrelevant desktop usage QD of 64..Quote:

that is if these results here are write through (seems they are).
the only deficit the 9260 has in compare to the 9211 is the ROC which might take some access time overhead and so deviate the bandwidth.
it would be very interesting though to see a softraid of 3 X25-M's on the ICHR or even the 790/850SB and 5 on the LSI card, or a strait compare to the 1231ML.
do u think that 3 x25-M's on ICHxR will be faster on softraid than 5 with LSI?Quote:

ok, will do
no,Quote:

i'm saying, the ICH10R with 2 or three drives has showed some amazing results,
iirc, they were much better then 3 drives on a raid controller,
what was suggested, is merging the two together, i.e - take 3 X25-M's and place them on the ICH10R, then add another 5 on the RAID controller, and soft RAID them all together.
you might get the best of both worlds,
some kick from the onboard controller and the rest of the speed (which it can't give you due to it's ~700MBps limits),
get from the LSI.
i'm wondering of the benefit and the possibility of it working well,
steveRO seems to have done it with his ACARD's http://www.xtremesystems.org/forums/...13&postcount=8
;) so u want 3 on ICHxR and 3 on LSI and i have to break 98000+ IO/s @ 4k file random? :D hehe is that it? :P
:), lol, no, this is not a competition you mad bull :lol2:,
you seem already shaking your hands for a fight :cheer2:,
this is about testing the best solution (or the fastest atleast).
and it's about taking 3 on the ICHR and the rest 5 on the LSI..;).
hmmmmm i want some competition ;)
We should have some competition that has to do only with storage !!!!!
Now for ur request how many IO/s do u think that it can score in random 4k @ 64QD? any predictions?
Here you go, 2 new configs with 16 workers.
The first one is 4KB random read only.
The second is 0,5-64KB random read QD 16-256 (1-8 pr worker, exp2 step). I will compare results to your single worker results.
EDIT: forgot to attach it :P
BTW, the 0,5-64KB random read test is set up with 1GB testfile and 10sec runtime (1s ramp + 9s run), so it's for no cache only usage.
no idea really,Quote:

the ICH10R should give some bust to the smaller random read and write patterns due to less operational overhead and so, should overall deliver better results for 3 SATA2 drives,
it might be happening due to a simpler design of the ICHR interface versus the PCI-e interface and might even due to the physical length the data has to travel, so eventually giving better access time and so higher IOPs count.
it seems to have never been tested before with such configuration, a 6 vs 6 drives for example are limited by the ICHR overall bandwidth and so would give a benefit to an 8 way controller card :).
E:
have a good look here, these are anvil's results gullars brought some months ago with 1-4 X25-V's.
as you can see, at QD of 64 and 4KB 100% read, your results on the 9260-4i with 4 X25-M's G1 are showing "mere" 45994 IOPs,
while anvil's 4 X25-V's on the ICH10R are showing 111,297 :),
so there should be some nice scaling :).
xmmm with 6 drives i could say round 800MB/s 200.000+ IOs ;) with 3+5 i would say round 310.000 IOs now with 9211+ICHxR+9260 3+3+2 loooooooooooooooool
no, seems you are going too far :),
maybe around 120,000 or 110,000 for 4 drives and another about 46,000 for another 4 so around 160,000 maybe 165,000,
the ICHR seems really good with the smaller random IOPs then the RAID controller cards,
the tests anvil has shown are for X25-V's which are slower then the X25-M's, so you might also get some nice bust over the 64KB :).
E:
this is done with 3 X25-M's on ICHR by Musho, some time ago:
100,000 IOPs 4KB 100% read QD of 128 :).

u wonna place ur bet? do not underestimate LSI with soft raid ;)

and its not even a soft raid ;)
WOOW,
hm, seen it somewhere, this is awesome,
so what is this all about :hm:?

anyway, this should be intriguing!
Onex, Tiltevros has posted results for 8R0 x25-M on LSI 9211-8i, and got about 106K 4KB random read @ QD 32 (with 1 worker).
With 8 workers, he got more than 125K @ QD 32, almost 185K @ QD 64, and just shy of 200K @ QD 128.
I've posted a couple of IOmeter configs for 16 workers, and i suspect we will see >200K IOPS @ 4KB random read (QD 64 or higher).
yes he will do very well...
i have hit over 200k on the 9260 :) (not random access though)
so the 9211 with his secret sauce should be able to get close.
if one of these cards, the 9260? got 211,421 IOPs up there, the softRAID should get probably around 240-260K.
soft raid is for girls:p:
canceled.
i like long walks by the beach, holding hands with my raid card, and candlelight dinners with my cpu. you?
my money says musho results the result of cache, soft raid of multiple raid arrays on ich....0+0!!!!!
:lol2:, though you will catch that :),
a girl with bristles :P.
anyway, no, really, seems like a nice ICH10R :).
E:
p.s - sorry, it wasn't very nice, just a stupid, silly remark :shrug:,
my bad...:(
u r not putting ur money on me???? :eek: :mad: :mad:Quote:
