MSA 2040 latency on raid 10

Hello

 

we have mSA2040.

We have 2 volume, 1 on raid 5 for data and low VM and other volume on raid 10 (10 disk of 900gb 10k) for 4 VM database server.

 

we have some IO lantency., my veeam one report me latency each 15min... and user complain for some application latency... 

 

My Hyperv host are connected with HBA card on the MSA. 4 wires per hba

 

423 IOPS and 11 MB/s and my server is on latency...
 
i can send any other information if necessary.

Re: MSA 2040 latency on raid 10

In order to troubleshoot Performance issue, there are many factors involved and it's not straight forward task. Some of the best practice to follow can be no hardware issue should exist, firmware need to be up to date, Connected system like Servers, SAN Switch all need to be up to date with driver/firmware as well.

Need to check what is the block size set at the Host and depends on that we should check if you want high IOPs or high throughput. Specifically, the smaller the I/O size, the more I/Os per second (IOPS) the SAN can process. However, the corollary to this is a decrease in throughput (as measured in MB/s). Conversely, as I/O size increases, IOPS decreases but throughput increases. When an I/O gets above a certain size, latency also increases as the time required to transport each I/O increases such that the disk itself is no longer the major influence on latency. 

Typically, workloads can be defined by four categories—I/O size, reads vs. writes, sequential vs. random, and queue depth.
A typical application usually consists of a mix of reads and writes, and sequential and random.
For example, a Microsoft® SQL Server instance running an OLTP type workload might see disk IO that is 8k size, 80 percent read, and 100 percent random.
A disk backup target on the other hand might see disk IO that is 64k or 256K in size, with 90 percent writes and 100 percent sequential.

The type of workload will affect the results of the performance measurement.

Check this below Customer Advisory and disable "In-band SES" ,

https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c05306564

You can check the below Customer Advisory as well.........in many situations this helped to improve performance,

https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c03473698

Check for ODX settings in Windows system. As per SPOCK it clearly says that Microsoft Offline Data Transfers (ODX) is not  supported with MSA2040.

https://h20272.www2.hpe.com/SPOCK/Content/ExportPDFView.aspx?Id=91895&typeId=2

Download the PDF and in page 4 you will get it's clearly mentioned that Microsoft Offline Data Transfers (ODX) is not  supported

If you still face performance issue then at the time of performance issue happening capture the below outputs atleast 10 to 15 times along with MSA log and log a HPE support case. They will help you.

# show controller-statistics
# show disk-statistics
# show host-port-statistics
# show vdisk-statistics
# show volume-statistics

One more suggestion, when you log any case or describe your technical issue that time more details required like Server model, what operating system installed, any Switch involved and running with what firmware, in Server all up to date or not specially HBA driver/firmware.......

 

Hope this helps!

Re: MSA 2040 latency on raid 10

Hello

 

first tks for help.

 

in fact ODX is enable on my server and i disabled it.

1 of my HBA don't have the last firmware i do it too.

Server are ML350gen9 and ML350gen8p. OS is Win2012R2 directly connected to MSA2040 with HBA.

 

On statsyou can see attachement.

For firmware MSA and disk you can see attachement too.

 

tks advance

stats attachement

Re: MSA 2040 latency on raid 10

From MSA information I see Controller firmware need to update to GL225R003. Please follow this link,

www.hpe.com/storage/MSAFirmware 

 

Drive firmware need to update for Drive model: EG0900JETKB. Please follow the link,

https://support.hpe.com/hpsc/swd/public/detail?sp4ts.oid=null&swItemId=MTX_b0bfab641434402d9faca54455&swEnvOid=4184#tab1

I checked statistics output but they looks fine to me. There is no CPU load or any high latency seen at the time of capture of outputs.

Anyway they are just captured once. First update MSA firmware for all components, update Server all components driver/firmware. Then reboot both MSA and Server. After that check if you face any performance. That time you need to capture following output at least 10 to 15 times by giving 2 minutes gap,

# show controller-statistics
# show disk-statistics
# show host-port-statistics
# show vdisk-statistics
# show volume-statistics

 

Note: Before you work on any performance issue thumb rule is you need to make sure your hardware is error free and all are up to date with driver/firmware

 

Hope this helps!

Re: MSA 2040 latency on raid 10

hello

 

i upgrade all firmware from server and msa2040.

 

result is the same, sometime we encoured some latency détected from my veaam One.

 

i would try to insert 15k disque for read cache, but it don't want... I suppose i must have SSD Drive to do this ?

 

tks for help.

Re: MSA 2040 latency on raid 10

Yes you must use SSD to configure read cache and that will help you in improving read latency only

If you have configured your system as per best practice and firmware/driver all up to date in all systems in your setup but still you face performance problem then you need to involve specialist to check your environment

 

Hope this helps!

Re: MSA 2040 latency on raid 10

Hello

 

tks for reply

 

I have now ssd drive.;; i try to follow guide, but my read cache option is grey, and i can't activate it.

 

do you have idea why ?

 

tks

 

 

Re: MSA 2040 latency on raid 10

Can you please check your Storage Pool if any Virtual Disk group exist or not because without any Virtual Disk Group you can't create read cache disk group.

Steps are straight-forward:

  1. First create a Disk-Group for the pool (you can't READ-CACHE without a back end storage)

  2. Then in the SMU (GUI) select _READ-CACHE and select the SSD(s)

You're done. 
 
I would start with just one SSD per pool (as per the best practices guide) and check your performance. 
 
 
Hope this helps!

Re: MSA 2040 latency on raid 10

tks for reply.

 

now we have linear volume.  Maybe my problem is here ?

is it possible to migrate to virtual ? without lost data ?

 

tks

Re: MSA 2040 latency on raid 10

As informed you earlier read cache concept works with Virtual Disk group and Virtual Pool only. It's not applicable for Linear vdisk.

Coming to your other query, in order to migrate data from Linear volume to Virtual Volume you need to use Host based application file copy feature. Please follow best practice white paper and refer page no 43 (Scenario 3:)
