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 | |
