Summary: mptsas & poor performance
Product: SCSI Drivers
Version: 2.5
Kernel Version: 2.6.34-020634rc1
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: scsi_drivers-other@kernel-bugs.osdl.org
ReportedBy: bexamous@gmail.com
Regression: No
The mptsas module from LSI's website, v4.18.00.00, performs much better than
the mptsas module included in the kernel, v3.something.
I'm only comparing sequential writes (dd if=/dev/zero of=zeros bs=1M), but...
6 drive MD RAID5 with fresh btrfs, writing 10GB of zeros with dd,
kernel version: <200MB/sec
LSI's v4.18.00.00: 395MB/sec
Pretty big difference. I've gone back and forth a few times,
enabling/disabling write cache on the drives, enabling/disabling ioc,
enabling/disabling filesystem barriers... I can make small changes in
performance but nothing compares to simply updating to v4.18.00.00.

scsi_drivers-other reports don't appear to be coming out on the
linux-scsi list.

Andrew,
Today I tried same steps as mentioned by you. In my case I am able to see both
the drivers
Performance is similar.
3.4.14 is driver version available at kernel.org
4.22.00.00 is driver LSI internally uses. [4.18.00.00 does not have support for
2.6.34 kernel]
I guess you must have done some changes to make sure 4.18.00.00 works with
2.6.34-020634rc1.
Both the case I am getting 190~210MB/sec.
Can you help me to reproduce ~395MB/sec using 4.18.00.00 ?

I think the only changes I made to 4.18.00.00 was to just not use mptlan
(since I have no need and it wouldn't compile on 2.6.34) and make a few
changes to mptsas.c (only to get it to compile on 2.6.34).

The <200MB/sec and 395MB/sec i was referring to was just using dd to write
zeros. Later on I ran bonnie and saved this.
Also system:
Tyan mobo wiht two E5410 CPUs, 12GB RAM, using onboard LSI 1068E. The LSI
connects to a HP SAS Expander. All drives are connected to the HP SAS
Expander. The drives are all 2TB WD GP drives WD20EADS, not the newer EARS
version.

OK. This is fine. All you did is just to make sure compilation is fine.

OK. This is fine. All you did is just to make sure compilation is fine.

I will collect similar h/w and redo the same test again. I will post my
findings once I am done with repro.

Hi Andrew & Kashyap,
It seems to me that the 4.22.00.00 driver from lsi is much faster than kernel
3.xx version driver. We have 16 WD SATA disks connected through lsi sas
expander to 1068e hba and linux md raid5 using these disks. The system has only
one quad-core E5405 CPU. With the new lsi driver, we get sequential dd read
performance up to 795MB/s and write performance up to 395MB/s which is almost
twice as the kernel 3.xx driver.
We will investigate different hardware setup further and let u know as soon as
possible.

BTW, I did not look into this as much, but using 3.xx there also seemed to
be a limit of ~600MB/sec between controller & expander. If I put two arrays
on the expander, each array by itself would do almost 500MB/sec in reads,
but together they couldn't break 600MB/sec. I didn't really look into this
further, maybe I was doing something wrong. ~600MB/sec, however, seems like
exactly 1/2 the bandwidth of the minisas cable between controlller &
expander.

I've been seeing a similar issue with a LSI 1068 connected to a Sun J4400 JBOD.
Solaris can drive a single 4-port PHY (12Gb/s) at about 1000 MB/sec but Linux
maxes out at 830 MB/sec running 2.6.32 included with RHEL 6 beta.
As I write to more disks at the same time, the throughput (MB/sec) per disk
starts dropping after the 7th disk:
#disks thruput tpdelta tp/disk expected tp
1 82 0 82.00 82
2 165 83 82.50 164
3 248 83 82.67 246
4 331 83 82.75 328
5 413 82 82.60 410
6 494 81 82.33 492
7 578 84 82.57 574
8 623 45 77.88 656
9 643 20 71.44 738
10 659 16 65.90 820
11 671 12 61.00 902
12 681 10 56.75 984
I'll do some tests with 4.22.00.00 now.

I found 4.22.00.00 to be a bit slower than the driver that comes with RHEL 6's
2.6.32.
I would really like to understand what is causing the throughput per disk to
drop when one starts writing to more than 7 disks at the same time over one
PHY.

kashyap: almost a year ago, you wrote "I will post my findings once I am done
with repro."
could you please give your customers a status update?

I see that change isn't in the latest Git?
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plain;f=drivers/message/fusion/mptbase.h;hb=6bc2b95ee602659c1be6fac0f6aadeb0c5c29a5d
Is there a reason it didn't go in?

I've asked a few times, but LSI has never picked it up. I can try linux-scsi
again, but it'd be useful to have at least a few supporters to confirm that it
doesn't break anything. :)

I was now moved to other role inside LSI, so could not focus on this. Sorry for
delay. My colleague "Lakshmi" is looking this issue and she wants helps to
reproduce the issue at LSI.
Latest, I was also not able to reproduce the this issue due to h/w components.
If someone can help Lakshmi to reproduce this issue locally, LSI can look at
the possible root cause.
BTW, Can you compare it with latest "upstream" vs "4.18.00.00" ?
