Example Conferencing Node server configurations

This section provides some example server configurations for Transcoding Conferencing Nodes, with an estimate of the capacity (in terms of many HD and SD connections — sometimes referred to as "ports") you can expect to achieve with each option. These figures assume that NUMA affinity and hyperthreading has been enabled.

Recommended server sizes

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

  Capacity (no. of connections)
160-185 HD / 390-425 SD 135-180 HD / 156-192 SD 110-132 HD / 240-290 SD
Cores /
Generation		 2x24-core Cascade Lake
(revised 2nd generation Xeon Scalable Processors, launched 2020)		 2x20-core Cascade Lake
(2nd generation Xeon Scalable Processors, launched 2019)		 2x20-core Skylake
(Xeon Scalable Processors, launched 2017)
