MSA 2060 Performance Graph

[metrobg]

I'm hoping someone can assist me or shed some light on my concern. We have just deployed an MSA 2062 configured with 6, 1.92 GB  SSD drives using raid 10 as the performance tier, and an MSA DP+ disk group consisting of 8, 1.2 TB 10k drives and 4 1.8 TB drives as the capacity tier. 

The array is being used in a vmware environment currently only hosting about 30 rather small Linux vm's and a couple of Windows servers. What's bothering me is that the latency graph hovers continually hovers between 30 ms and 25 ms, occasionally dropping as low as 15 ms when there is a spike in IO activity. Is that normal, or am I missing something?  Could disk scrubbing be affecting the latency?  Any feedback is greatly appreciated.

Hi,

you can disable scrubbing for some days to check: set advanced-settings background-scrub off

If so, you can schedule scrubbing during low usage time or enable or disable it by schedule.

You will find the commands in: HPE MSA 1060/2060/2062 CLI Reference Guide

Hello@metrobg,

Please check the link below for HPE MSA 2060 storage CLI. 
https://support.hpe.com/hpesc/public/docDisplay?docId=a00105313en_us&docLocale=en_US 
You may schedule the disk group scrubbing by using SMU.
Settings > System > Properties > Scrub properties > Enable/disable Disk group scrub > Click on "Create a schedule."

Hope this helps!
