IBM Sametime

System requirements

The hardware requirements listed below are the minimum requirements for a small, pilot deployment and will not be sufficient for large-scale production deployments. Hardware resources should be planned based on usage expectations.

Known Issues

In certain scenarios, Technotes or APARs on the Sametime Support site document known problems or cases where IBM has determined that a particular device, operating system, browser, or software application cannot be integrated with the Sametime software platform without extensive testing or extensive code changes
