New !! Open unofficial storage performance thread

Hello everybody,

the old thread seems to be sooooo looooong - therefore I decided (after a discussion with our moderator oreeh - thanks Oliver -) to start a new thread here.

Oliver will make a few links between the old and the new one and then he will close the old thread.

Thanks for joining in.

We saw similar numbers on our PS4000E until we ran the configuration script included with the multipathing extension module on each of the hosts. High latency and low IOPS across the board. Afterwards nearly half the latency and double the IOPS. Have the results at the office.

Thanks for the tip.  I will try this very soon.  I plan on installing an addtional 4 pNICs into each host this week.  I guess this was perfect timing.

I will post the results when finished.

Wow, that formatting turned out horrible. Both non-MEM and MEM results are there, in the read results there were large improvements. Random is fairly even between then two, with slightly better performance on the Real Life bench on the MEM-enabled system.

Hi all,

I'm getting strange results with http://vmktree.org/iometer/ and IOMeter 1.1.0

While analyzing the .csv, it seems that the csv output isn't interpreted as expected, the CGI taking the 9th column "Write MBps (Decimal)" instead of the 12th "Average Response Time" for the latency.
As an easy way to see that, I'm getting 0ms for the 100% read test.
I'm suspecting too that the CPU load isn't either picked where it should be. Could someone check on its side ?

Here attached is one of my CSV with faulty interpretation.

attached CSV

Solved ! IOMeter 1.1.0 (devel) doesn't have the expected output format. Use the regular versions

Hello all,

Here are some results from our Netapp C-Mode system currently being put through it's paces.  So far I am pretty happy with the performance, but there is still some tweaking to do before we go into production with it.

First up, results with 2x SAS 600GB 15k shelves (38 data disks):

Next, results using SATA drives + SSD in a Flash Pool (SSD cache in front of the SATA drives).  Only 12 SATA drives in this aggregate, but will likely increase that to the full 24 drive shelf, so that should help the Real Life test result.

Switched from Dell Multipath Module to Round Robin because of Enterprise licensing requirement for 3rd party multipathing. Improvements across the board (see above!) But one test either way probably doesn't count as evidence.

Seems to me you didnt get that large of an increase but any improvement helps. Try setting the round robin policy limits to IOPs, and set the limit to 1. Re-run your tests and see the difference Smiley Happy

This is what I run from PowerCLI to make the changes to the entire cluster and all the LUN's:

$Cluster = Read-host "Enter Cluster Name"
foreach ($vmhost in get-cluster $Cluster | get-VMHost){
        Connect-VIServer -Server $vmhost.Name -User root -Password <yourpasswd>
        $esxcli = Get-EsxCli -VMHost $vmhost.Name
       
        $esxcli.storage.nmp.satp.set($false,"VMW_PSP_RR","VMW_SATP_SYMM")
       
        foreach ($lunpath in $esxcli.storage.nmp.device.list() | where {$_.device -like "naa.*"}){
          
                   
                    $esxcli.storage.nmp.device.set($null,$lunpath.Device, "VMW_PSP_RR")
                    $esxcli.storage.nmp.psp.roundrobin.deviceconfig.set($null,$lunpath.Device,1,"iops",$null)
