Allocate storage I/O resources to virtual machines based on importance by assigning a relative amount of shares to the virtual machine.
See vSphere Storage for information on creating VM storage policies and defining common rules for VM storage policies.
- Browse to the virtual machine in the vSphere Client.
- To find a virtual machine, select a data center, folder, cluster, resource pool, or host.
- Click the VMs tab.
- Right-click the virtual machine and click Edit Settings.
- Click the Virtual Hardware tab and select a virtual hard disk from the list. Expand Hard disk.
- Select a VM storage policy from the drop-down menu.
If you select a storage policy, do not manually configure Shares and Limit - IOPS.
- Under Shares, click the drop-down menu and select the relative amount of shares to allocate to the virtual machine (Low, Normal, or High).
You can select Custom to enter a user-defined shares value.
- Under Limit - IOPS, click the drop-down menu and enter the upper limit of storage resources to allocate to the virtual machine.
IOPS are the number of I/O operations per second. By default, IOPS are unlimited. You select Low (500), Normal (1000), or High (2000), or you can select Custom to enter a user-defined number of shares.
- Click OK.
