About scsi device queue depth

About scsi device queue depth

[John Garry]

Hi,

I was looking at some IOMMU issue on a LSI RAID 3008 card, and noticed 
that performance there is not what I get on other SAS HBAs - it's lower.

After some debugging and fiddling with sdev queue depth in mpt3sas 
driver, I am finding that performance changes appreciably with sdev 
queue depth:

sdev qdepth	fio number jobs* 	1	10	20
16					1590	1654	1660
32					1545	1646	1654
64					1436	1085	1070
254 (default)				1436	1070	1050

fio queue depth is 40, and I'm using 12x SAS SSDs.

I got comparable disparity in results for fio queue depth = 128 and num 
jobs = 1:

sdev qdepth	fio number jobs* 	1	
16					1640
32					1618	
64					1577	
254 (default)				1437	

IO sched = none.

That driver also sets queue depth tracking = 1, but never seems to kick in.

So it seems to me that the block layer is merging more bios per request, 
as averge sg count per request goes up from 1 - > upto 6 or more. As I 
see, when queue depth lowers the only thing that is really changing is 
that we fail more often in getting the budget in 
scsi_mq_get_budget()->scsi_dev_queue_ready().

So initial sdev queue depth comes from cmd_per_lun by default or 
manually setting in the driver via scsi_change_queue_depth(). It seems 
to me that some drivers are not setting this optimally, as above.

Thoughts on guidance for setting sdev queue depth? Could blk-mq changed 
this behavior?

Thanks,
John

In general, for spinning rust, you want the minimum queue depth
possible for keeping the device active because merging is a very
important performance enhancement and once the drive is fully occupied
simply sending more tags won't improve latency.  We used to recommend a
depth of about 4 for this reason.  A co-operative device can help you
find the optimal by returning QUEUE_FULL when it's fully occupied so we
have a mechanism to track the queue full returns and change the depth
interactively.

For high iops devices, these considerations went out of the window and
it's generally assumed (without varying evidence) the more tags the
better.  SSDs have a peculiar lifetime problem in that when they get
erase block starved they start behaving more like spinning rust in that
they reach a processing limit but only for writes, so lowering the
write queue depth (which we don't even have a knob for) might be a good
solution.  Trying to track the erase block problem has been a constant
bugbear.

I'm assuming you're using spinning rust in the above, so it sounds like
the firmware in the card might be eating the queue full returns.  I
could see this happening in RAID mode, but it shouldn't happen in jbod
mode.

For this case, it seems the opposite - less is more. And I seem to be 
hitting closer to the sweet spot there, with more merges.

I am only doing read performance test here, and the disks are SAS3.0 
SSDs HUSMM1640ASS204, so not exactly slow.

Not sure on that, but I didn't check too much. I did try to increase fio 
queue depth and sdev queue depth to be very large to clobber the disks, 
but still nothing.

"Spinning rust" is starting to wear a bit thin. In power electronics
(almost) pure silicon is on the way out (i.e. becoming 'legacy').
It is being replaced by Silicon Carbide and Gallium Nitride.
What goes around, comes around :-)

What does the performance number mean? IOPS or others? What is the fio
io test? random IO or sequential IO?

Right, the behavior basically doesn't change compared with block legacy
io path. And that is why sdev->queue_depth is a bit important for HDD.

So far, the sdev queue depth is provided by SCSI layer, and blk-mq can
queue one request only if budget is obtained via .get_budget().

I think cheaper SSDs have a write latency problem due to erase block
issues.  I suspect all SSDs have a channel problem in that there's a
certain number of parallel channels and once you go over that number
they can't actually work on any more operations even if they can queue
them.  For cheaper (as in fewer channels, and less spare erased block
capacity) SSDs there will be a benefit to reducing the depth to some
multiplier of the channels (I'd guess 2-4 as the multiplier).  When
SSDs become write throttled, there may be less benefit to us queueing
in the block layer (merging produces bigger packets with lower
overhead, but the erase block consumption will remain the same).

For the record, the internet thinks that cheap SSDs have 2-4 channels,
so that would argue a tag depth somewhere from 4-16

Possibly ... the stats on most manufacturer SSDs don't give you
information about the channels or spare erase blocks.

If it's an SSD it's likely not giving the queue full you'd need to get
the mid-layer to throttle automatically.

First of all: are these 'real' SAS SSDs?
The peak at 32 seems very ATA-ish, and I wouldn't put it past the LSI 
folks to optimize for that case :-)
Can you get a more detailed picture by changing the queue depth more 
finegrained?
(Will get you nicer graphs to boot :-)

So those figures are x1K IOPs read performance; so 1590, above, is 1.59M 
IOPs read. Here's the fio script:

[global]
rw=read
direct=1
ioengine=libaio
iodepth=40
numjobs=20
bs=4k
;size=10240000m
;zero_buffers=1
group_reporting=1

;cpumask=0xffe
;cpus_allowed=1-47
;gtod_reduce=1
;iodepth_batch=2
;iodepth_batch_complete=2
runtime=60
;thread
loops = 10000

Well, based on my testing, default sdev queue depth seems too large for 
that LLDD ...

Is there any effect on random read IOPS when you decrease sdev queue
depth? For sequential IO, IO merge can be enhanced by that way.

Yeah, it is similar with NVMe since people often cares latency more for
SSD.

They're HUSMM1640ASS204 - not the fastest you can get today, but still 
decent.

I'll see about fine-grained IOPs vs depth results ...

I have seen upto 10-channel devices mentioned being "high end" - this 
would mean upto 40 queue depth using on 4x multiplier; so, based on 
that, the current value of 254 for that driver seems way off.

For my particular disk, this is the datasheet/manual:
https://documents.westerndigital.com/content/dam/doc-library/en_us/assets/public/western-digital/product/data-center-drives/ultrastar-sas-series/data-sheet-ultrastar-ssd1600ms.pdf

And I didn't see explicit info regarding channels or spare erase blocks, 
as you expect.

So it seems that the queue depth we select should depend on class of 
device, but then the value can also affect write performance.

As for my issue today, I can propose a smaller value for the mpt3sas 
driver based on my limited tests, and see how the driver maintainers 
feel about it.

I just wonder what intelligence we can add for this. And whether LLDDs 
should be selecting this (queue depth) at all, unless they (the HBA) 
have some limits themselves.

You did mention maybe a separate write queue depth - could this be a 
solution?

Thanks,

John - Can you check your test with rq_affinity = 2  and nomerges=2 ?

I have noticed similar drops (whatever you have reported) -  "once we reach
near pick of sdev or host queue depth, sometimes performance drop due to
contention."
But this behavior keep changing since kernel changes in this area is very
actively happened in past. So I don't know the exact details about kernel
version etc.
I have similar setup (16 SSDs) and I will try similar test on latest kernel.

BTW - I remember that rq_affinity=2 play major role in such issue.  I
usually do testing with rq_affinity = 2.

John,

In that datasheet, I see the model number designator "MR", which
stands for "Multi level cell, read-intensive (2 drive writes per
day)".

Compare that to the 1600MM drive: "Multi level cell, mainstream
endurance (10 drive writes per day)":
https://documents.westerndigital.com/content/dam/doc-library/en_us/assets/public/western-digital/product/data-center-drives/ultrastar-sas-series/data-sheet-ultrastar-ssd1600mm.pdf

Also, note that the quoted "Write IOPS (max IOPS, random 4k)" on the
datasheet is 30,000 for the 1600MR drive, and 100,000 IOPS for the
1600MM drive.

Bryan

SSD manufacturers don't want us second guessing their device internals
which is why the mostly don't publish the details.  They want to move
us to a place where we don't do any merging at all and just spray all
the I/O packets at the device and let it handle them.

Your study argues they still aren't actually in a place where reality
matches their rhetoric but it you code latency heuristics based on my
guesses they'll likely be wrong for the next generation of devices.

Right, manufacturers simply aren't going to give us that information. 
I also suspect the device won't return queue full usefully either so we
can't track that meaningfully either.

Remember also that all SSDs have a flash translation layer which
transforms our continuous I/O into a scatter/gather list.  This does
argue there are diminishing returns from merging I/Os anyway and
supports the manufacturer argument that we shouldn't be doing merging.

I think the question for us is: if we do discover additional latency in
an SSD read/write queue what do we do with it?  For spinning rust,
using spare latency to merge requests is a definite win because the
drive machinery is way more efficient with contiguous reads/writes,
what would be a similar win with SSDs?

Well, it does today.  queue full works for most non SSD devices and it
allows us to set a useful queue depth.  We also have the norotational
flag in block to help.

It will run counter to the SSD manufacturers "just give us all your
packets ASAP" mantra so most commercial driver vendors won't want it
changed.

I suspect it's not in the block layer at all.  I'd guess the best thing
we can do is report on read and write latency and let something in
userspace see if it wants to adjust the queue depth.

> You did mention maybe a separate write queue depth - could this be a 
> solution?

I was observing that the gating factors for the read and write latency
characteristics are radically different for SSDs, so I would really
expect optimal queue depths to be different on read and write requests.
Now whether there's a benefit to using that latency is a different
question.  If we had a read and a write queue depth, what would we do
with the latency in the write queue?  The problem on writes is the
device erasing blocks ... merging requests doesn't do anything to help
with that problem, so there may be no real benefit to reducing the
write queue depth.

There is a convention of SSD manufacturers quoting a "drive writes per
day" rating for their drives, especially if they will offer a product
line with a "read-intensive" model for mostly-read workloads, and then
charge more for a model that has a higher "drive writes per day"
rating, and maximum IOPS rating.

(I found a "mainstream endurance" model variant for the Ultrastar
SSD1600 series, the SSD1600MM.  There are more details in an email
that I sent a little earlier in this thread.)

We have to remember that hard disk drives and SSDs have different
mechanisms, therefore they have different behaviors in reaction to the
host commands.

A hard disk drive usually has one mechanical arm that moves read-write
heads across a platter.  To reduce the amount of "chasing back and
forth" that the drive head needs to do, there are strategies like
merging requests into larger sequential requests, and using a cache
somewhere (on the drive, or on the controller, or in the operating
system).

When an SSD encounters the "write cliff", where its flash translation
layer is busy with its tasks that are internal to the firmware, what
else can the host do to "make things easier" for the FTL, and
eventually recover to full write performance?

Right now, it seems like the best way to recover that performance is
to "stop performing sustained random writes so often," but that seems
counter to the goal of using the drive to its fullest performance
potential.

Other medium types may not have this problem.  For example, the Intel
Optane 800P that was released a few years ago uses 3D XPoint instead
of NAND, and it does not have a "write cliff" at all.  In fact, you
have the opposite problem, in that case: you have to start worrying
about potentially exceeding the drive-writes-per-day rating (which I
believe Intel quoted at hundreds of terabytes written over the 5-year
warranty period).

Hi Ming,

fio randread results:

fio queue depth 40
sdev qdepth	fio number jobs* 	1	10	20
8					1308K	831K	814K
16					1435K	1073K	988K
32					1438K	1065K	990K
64					1432K	1061K	1020K
254 (default)				1439K	1099K	1083K


fio queue depth 128
sdev qdepth	fio number jobs* 	1	10	20
8					1310K	860K	849K
16					1435K	1048K	958K
32					1438K	1140K	951K
64					1438K	1065K	953k
254 (default)				1439K	1140K	1056K

So randread goes in the opposite direction (to read wrt queue depth).

Many disk drives and SSDs only return QF/TSF when they are out of actual
command slots (so typically 255). There is often a watertight barrier
between the transport-specific command processing and the media
management code. Very sad.

So while the exponential backoff approach works great for disk arrays,
it's hit or miss with drives. And it's really hard to come up with a
good heuristic since the optimal queue depth is highly workload and
device-specific.

We had a few folks looking at managing write queue depth based on
completion latency a couple of years ago but it didn't come to fruition.

And if IO priorities are in use... And there is the latency target specs coming
soon to make things even more interesting :)

Hi Kashyap,

As requested:

rq_affinity=1, nomerges=0 (default)

sdev queue depth	num jobs=1
8			1650
16			1638
32			1612
64			1573
254			1435 (default for LLDD)

rq_affinity=2, nomerges=2

sdev queue depth	num jobs=1
8			1236
16			1423
32			1438
64			1438
254			1438 (default for LLDD)

Setup as original: fio read, 12x SAS SSDs

So, again, we see that performance changes from changing sdev queue 
depth depends on workload and then also other queue config.

Thanks,
John

What is an issue with rq_affinity=2 and nomerges=2 ?
It looks like - "Dropping IOPs from peak (1.6M) is not an issue here but we
are not able to reach peak IOPs. IOPS increase gradually and it saturate."

Can you send me "dmesg" logs of your setup. What is host_busy counter while
you run your test ? I am not able to duplicate the issue on my setup.

To avoid any io merge issue, can we use rand_read data ?

For randread:

rq_affinity=1, nomerges=0 (default)
fio queue depth 128
sdev qdepth   		num jobs=1
8			1300K
16			1435K
32			1438K
64			1438K
254 (default)		1439K

rq_affinity=2, nomerges=2
sdev queue depth	num jobs=1
8			1313
16			1438
32			1438
64			1438
254 (default)		1438
