When you check out a View desktop to run on your local computer, the hardware on the client computer must support both the local system and the virtual machine that now runs on it.

Checking out a View desktop that uses virtual hardware version 8 is not supported. If you use vSphere 5 to create virtual machines that will be sources for local mode desktops, be sure to create virtual machines that use virtual hardware version 7.

Processor Requirements describes the hardware requirements for various View desktop operating systems.

ATI Radeon HD 2600 and above

If you use a default setup for the operating system in the View desktop, the actual disk space needs are approximately the same as those for installing and running the operating system and applications on a physical computer.

For example, Microsoft recommends 16GB of hard disk space for a machine that runs a 32-bit Windows 7 operating system. If you configure a 16GB virtual hard disk for a 32-bit Windows 7 virtual machine, only the amount of disk space actually used is downloaded when you check out the local desktop. For a desktop that is allocated 16GB, the actual download size might be 7GB.

After the desktop is downloaded, the amount of disk space used can grow to 16GB if you configured a 16GB hard disk. Because a snapshot is taken during replication, an additional equivalent amount of disk space is required. For example, if 7GB of disk space is currently being used for the local desktop, the snapshot consumes an additional 7GB on the client computer.

IDE and SCSI hard drives are supported.

You need enough memory to run the host operating system on the client computer, plus the memory required for the View desktop's operating system and for applications on the client computer and the View desktop. VMware recommends that you have 2GB and above for Windows XP and Windows Vista, and 3GB and above for Windows 7. For more information on memory requirements, see your guest operating system and application documentation.

The total amount of memory you can assign to all virtual machines running on a single computer is limited only by the amount of RAM on the computer. The maximum amount of memory for each View desktop on 32-bit client computers is 8GB and on 64-bit computers it is 32GB.

A 32-bit display adapter is recommended. 3D benchmarks, such as 3DMark '06, might not render correctly or at all when running Windows Vista or Windows 7 virtual machines on some graphics hardware.

To play video at 720p or higher requires a multiprocessor system.
