Designing your virtual SAN

The design of your virtual SAN affects both its performance and its reliability for production use. Use the concepts and practices in this manual when installing and managing your virtual SAN to ensure optimal performance and reliability.

Configuration requirements

The following configuration requirements are prerequisites for HP to support your virtual SAN for production use.

A qualified server running VMware ESX Server. Qualified servers are listed in VMware ESX Server systems compatibility guide, which can be found at

http://www.vmware.com/resources/compatibility/search.php.

A qualified server running Microsoft Hyper-V Server. To verify the server is listed and qualified for Hyper-V Server, go to http://windowsservercatalog.com/results.aspx?&bCatID=1283& cpID=0&avc=11&ava=0&OR=1&PGS=25, and then search for “Hyper-V” as an additional qualification. See supported Windows versions.
