Example Conferencing Node server configurations

The table below gives some example server configurations for Transcoding Conferencing Nodes, with an estimate of how many HD (720p) connections (or ports) you can expect to achieve with each. Note that the lower figure represents normal configuration, and the upper figure represents what you can expect with NUMA affinity enabled.

Recommended server sizes

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

  Capacity (no. of connections)
100-132 HD / 200-280 SD 55-75 HD / 100-150 SD 50-60 HD / 100-140 SD 40-50 HD / 80-100 SD
