Example Conferencing Node server configurations

This section provides some example server configurations for Transcoding Conferencing Nodes, with a capacity estimate of how many HD and SD connections you can expect to achieve with each option. The lower figure in the range represents normal configuration, and the upper figure represents what you can expect with NUMA affinity enabled. Note that the number of connections are also sometimes referred to as ports.

Recommended server sizes

For the Pexip Infinity platform, the following server configurations provide maximum performance for cost:

    Capacity (no. of connections)
110-140 HD / 220-280 SD 100-132 HD / 200-280 SD 55-75 HD / 100-150 SD
