Modifying disk shares on a VM
Setting custom disk shares is particularly useful when you want to make sure that a VM receives a larger chunk of the disk bandwidth during contention. By default, the disk share is set to Normal (1000). The other presets available to set custom shares are Low (500) and High (2000).
In this recipe, we will learn how to set custom disk shares.
How to do it...
The following procedure explains how to set customize disk share values on a VM:
Go to Edit Settings for the VM that you are concerned with.
Expand the hard disk entry, select a planned shares value, and click on OK to confirm your settings. You can also set a Limit - IOPs value if necessary:
SIOC will take into account the custom share value when throttling the VMkernel device queue.
How it works...
Disk shares are applied at the virtual machine disk (VMDK) level. The shares will come into effect only when there is contention for the disk bandwidth. The shares are relative to the shares set for the other VMDKs...
