A commercial support contract is appropriate if you're running XenServer in a production environment, particularly if downtime is a critical component of your SLA. It's important to note that commercial support is only available if the deployment follows the Citrix deployment guidelines, uses third party components from the Citrix Ready Marketplace, and is operated in accordance with the terms of the commercial EULA.
- Citrix 24x7 worldwide support
All commercially licensed XenServer users are entitled to Citrix Support, offering unlimited-incident 24x7 worldwide technical support in nine languages across the globe. Purchase of a support contract which is then applied to a XenServer installation entitles support services on that installation.
- Indemnification and license protections
Commercial users of XenServer are not subject to any liabilities stemming from the open source development of the product. Citrix ensures that all contributions to the product meet all legal requirements for software licensing.
- Premium functionality
XenServer commercial licenses are available in two editions; Standard and Enterprise. If you are simply looking for a commercial support contract, then Standard Edition is the correct choice. Details on the features in each edition are in the XenServer 6.5 feature matrix.
Support for XenServer is sold per physical socket and includes both software maintenance and support. A license is required for all populated physical CPU sockets.
