Check these SAN IO stats?

[howartp]

Can anyone have a look at these and tell me if they look good/bad/otherwise?

 

It's our IBM SAN. Store 3 and 4 are SAS disks, store 5 and 6 are SATA.

 

Our vSphere 5.1 estate occupies all of it.

 

Data copy speeds between disks (even two disks on the same VM on the same array/LUN) seems very slow; I don't have hard numbers at the moment, but something doesn't seem right somewhere.

 

 

Cheers.

I'm no expert but those figures don't look high to me (except vol 6), what kind of san is it? ISCSI?

 

I used a 1GB ISCSI san before and the bad iops were around the 2000's. You could test the throughput as well:

But you could measure the iops:

It's Fibre Channel.

 

Vol 6 is where the student user areas are stored.

 

I'll have a look at the Gatt link.
