SAN Transfers with System Center Virtual Machine Manager System Center Virtual Machine Manager can perform the following types of SAN

transfers between a source and a destination computer:

  • Storing a virtual machine from a virtual machine host in a System Center Virtual Machine Manager library

  • Deploying virtual machines from a System Center Virtual Machine Manager library to a host

  • Migrating a virtual machine from one host to another

When a SAN transfer is performed, the LUN that contains the virtual machine is remapped from the source to the destination computer instead of the files being transferred over the network. Therefore, SAN transfers are much faster than standard network transfers and are independent of the file size.

If SAN transferring is available, System Center Virtual Machine Manager will use it automatically. This behavior can be overridden to force System Center Virtual Machine Manager to use a network transfer.

Before System Center Virtual Machine Manager can be used for a SAN file transfer, the following configuration steps must be completed:

  • 1.

    Install Virtual Disk Service (VDS) 1.1, a component of Windows Server 2003 R2, on each computer that will serve as either a source or destination.

  • 2.

    Install the VDS hardware provider only on the System Center Virtual Machine Manager server.

  • 3.

    Install an iSCSI initiator for an iSCSI SAN.

  • 4.

    Install a multipath I/O (MPIO) driver for a Fiber Channel SAN, even if it is using only one HBA port.

Before System Center Virtual Machine Manager can be used for a SAN file transfer on Windows Server 2008/Hyper-V Hosts, the following configuration steps must be completed:

  • 1.

    Install an iSCSI initiator for an iSCSI SAN.

  • 2.

    Install a multipath I/O (MPIO) driver for a Fiber Channel SAN, even if it

is using only one HBA port.

System Center Virtual Machine Manager 2008 R2 Rapid Provisioning with SAN Some SANs have resources to clone a LUN containing a VHD and presenting it to

the host. In order to use System Center Virtual Machine Manager for the OS customization and IC installation, System Center Virtual Machine Manager R2
