This section describes Vocera Voice Server and the VMware requirements.

Minimum Memory Size or Configuration 8 GB RAM

Important: Vocera has validated that the Vocera Server works with the above requirements. However, we understand that every virtual infrastructure has unique characteristics. Consequently, you may need to deviate from the required configuration. If you encounter performance issues with virtualized Vocera Servers, Vocera Technical Support will work with your VMware administrator to help identify the cause of the problem and make recommendations to help fix or mitigate the problem. The recommendation could be to move the Vocera Server to a host with more available resources or higher performing disk capabilities. In some cases, Vocera Technical Support may recommend migrating to physical hardware if the virtual environment is not able to maintain the level of performance required by the Vocera solution.

Applications on the Same Host

The following applications are supported running on the same host as a virtualized Vocera Server:

Important: For hardware redundancy, Vocera recommends a separate physical host for each Vocera Server cluster node.
