The Sametime Media Manager is available for installing on the Linux
® or Microsoft
® platforms only. You should review the following considerations before installing components of an IBM
® Sametime Media Manager. Audio and video are managed with the Sametime Media Manager server. Audio and video services provided by the Sametime Media Manager have been tested and optimized for sessions with 20 participants. The actual number of participants per session will vary up or down based on network and environmental conditions.
In this release, a Sametime deployment can support only one stand-alone Media Manager server, or one cluster of Media Manager servers. This restriction is due to a limitation with the current version of the Sametime System Console.
A Media Manager deployment consists of a Conference Manager, a SIP Proxy and Registrar, and a Packet Switcher. A standalone Media Manager deployment can have multiple Packet Switchers to support a higher number of simultaneous audio and video conferences. Each Packet Switcher runs on a separate WebSphere
® node and is not clustered; the Conference Manager handles the workload distribution among them.
The Sametime System Console can only administer one Media Manager instance. The individual components of the Media Manager instance may be individually clustered to provide failover and high availability, deployed as standalone servers, or installed on the same server – but only one Media Manager deployment can be administered from a given Sametime System Console.
The Packet Switcher is not administered from the console, so it is not affected by this limitation; however the Conference Manager and the SIP Proxy and Registrar components are administered from the console, so your planning must take this limitation into consideration.
Example 1: Two standalone Conference Manager servers cannot be administered from the same Sametime System Console.
Example 2: A Conference Manager cluster and a SIP Proxy and Registrar cluster can both be administered from the same console. This is the recommended topology for enterprise customers.
Example 3: A Conference Manager cluster and a standalone SIP Proxy and Registrar server can be administered from the same console.
