Each VM gets a difference disk.Īll VDA belonging to the catalog and datastore will reference the copy created in Step 2 for most reads request. The disk is thin provisioned (if supported by the storage) and will increase to the maximum size of the base VM if required. A unique difference disk used to store any writes made to the VM.Functionality within the XenDesktop Controllers creates the identity disks.
A unique identity disk (16MB) used to provide each VM with a unique identity.This is the same disk identified in step 2 of the catalog creation process. The full snapshot, which is read-only and shared across the VMs just created.If you have multiple storage repositories defined, then each one will get the following types of disks: However, in addition to the two disks for each VM, a master will also be stored in the same storage repository. MCS creates the number of VMs specified in the create catalog wizard with two disks defined for each VM. This step creates the unique AD identities to be used later in the process MCS adds these desktops into Active Directory. This will utilize the amount of space used for your complete image. MCS creates a full copy of the point in time snapshot and places this on each storage repository defined in the host connection. MCS creates a snapshot (thin) of the master VM unless you selected a snapshot, which will not create another snapshot. Note: After completion, the machines will be of type ‘Existing’ and will still be power managed and controlled by XenDesktop, however XenDesktop will no longer have ownership of the machines in the respect that they cannot be cleaned up and deleted by XenDesktop anymore.ĭuring the dedicated catalog creation process, the following occurs: This article outlines the process to move to another datastore. BackgroundĬustomers using XenDesktop Machine Creation Service (MCS) with dedicated catalog and VMWare hypervisor may want to relocate the desktops to another datastore for various reasons such as datastore running out of space or datastore performance. This article describes how to migrate a dedicated catalog to another datastore.
