General System Requirements
Cisco Webex Meetings Server (CWMS) is compatible with Cisco UCS servers that meet or exceed the specifications presented in this section.
Important |
When you perform an upgrade to a major release of CWMS, such as to Release 2.0 or Release 2.5 from Release 1.x, the ESXi hosts (Cisco UCS server) where the Admin virtual machine is located require a minimum of 1.5-TB of free disk space. Refer to the section in this document that describes the different size user systems that begin with the 50-user System. During an upgrade, there are two sets of virtual machines on your network at the same time; the original virtual machines running Release 1.x and the upgrade virtual machines to support the new release. For more details, see the "Upgrading the System" section in the CWMS Administration Guide at http://www.cisco.com/en/US/products/ps12732/prod_installation_guides_list.html. |
