[I'm a newbie to all this so please go easy on me]
This might well be a question for the vmware forums, but I thought I would start here. We recently purchased a HUS110 for our small vm platform (3 x ESXi 5.1 hosts). Our 110 has the standard 2 x 1GB interfaces per controller.
Our storage is split across two volumes (vol1 & vol2), which are within a single DP Pool.
Within vSphere Client > Host > Performance > if I edit the chart to show real-time Disk performance, select objects 'Hus Controller 0' and 'Hus Controller 1' and select 'Commands Issued' in the counters section, my starts are...
Hus Controller 0, Average = 266
Hus Conrtoller 1, Average = 576
Hus Controller 0, Average = 508
Hus Conrtoller 1, Average = 2024
Hus Controller 0, Average = 2269
Hus Conrtoller 1, Average = 13
Host 3 seems the worst. These stats have remained consistent throughout the day. I checked the VM's running on Host3 and all have their virtual hard disks on vol1.
Is this normal? How are the volumes linked to the controllers?
