There are several ways to get more disk storage available for your VMs running on VMware ESX. Adding an extra datastore is an option, but having multiple datastores creates an extra administrative overhead since you now have multiple datastores to monitor.
According to EMC this “adaptive queue depth” setting is not yet supported (June 2013). The full article can be found on this link. It is known as Primus solution id emc279718.
My advice would be not to use this setting until EMC certifies this setting for use with their arrays.
The exact Article is as follows:
| What is the recommended LUN queue depth throttling in VMware ESX/ESXi? | |
|
|
| OS: VMware ESX / ESXi Product: CLARiiON / Symmetrix and I assume VNX as well |
|
| According to Engineering, enabling the adaptive queue depth algorithm is NOT documented in the Host Connectivity Guide or the EMC Support Matrix. The recommendation is to use the default setting which is disable adaptive queue depth. Additional checks with E-Lab VMware quality engineers, E-Lab testing is done with the default setting. |
