This topic describes how to add disks to a virtualization platform for the local block gateway to use for caching.
Add disks to VMware vSphere
- Log on to the VMware vSphere virtualization platform.
- On the Configure tab, choose . Click Edit.
- On the Virtual Hardware tab, from the New device list, select New Hard Disk. Click Add.
After the disk is added, a New hard disk folder appears.
- Set the size of the new hard disk.
We recommend that you use thick provisioning to deploy the disk. Expand the New hard disk folder. Set the Type to Thick Provision Lazy Zeroed or Thick Provision Eager Zeroed to achieve better I/O performance.
Add disks to Hyper-V
The host must be restarted if you add disks by using an IDE controller. However, you do not need to restart the host if you add disks by using a SCSI controller. We recommend that you use a SCSI controller to add disks.
- Log on to the Hyper-V virtualization platform.
- Choose Hard Drive. Click Add.
, and select
- On the Hard Drive tab, select Virtual Hard Disk, and click New.
- Follow the new virtual hard disk wizard to add the hard disk.
Note the following settings:
- On the Choose Disk Type tab, select Dynamically expanding.
- On the Configure Disk tab, select Create a new blank virtual hard disk, and set the disk size.
The size of a single cache disk must be greater than 20 GB for higher I/O throughput. For more information about the cache configuration, see Block gateways.
- Return to the Hard Drive tab, and click Apply.
