Example Conferencing Node server configurations

The table below gives some example server configurations for 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 VMware NUMA affinity enabled.

Recommended server sizes

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

	Capacity (no. of connections)
	55-75 HD / 100-150 SD	50-60 HD / 100-140 SD	40-50 HD / 80-100 SD
Cores/ Generation	28-core Broadwell (E5-2600 v4 generation, launched 2016)	24-core Haswell (E5-2600 v3 generation, launched 2014)	20-core Ivy Bridge (E5-2600 v2 generation, launched 2013)
CPU	2 x Intel E5-2680v4 14 core 2.4 GHz 35 MB cache	2 x Intel E5-2680v3 12 core 2.5 GHz 30 MB cache	2 x Intel E5-2680v2 10 core 2.8 GHz 25MB cache
RAM	8 x 4 GB or 8 x 8 GB (minimum 4 RAM chips per CPU for max memory bandwidth)
Network	1 Gbps NIC (we recommend dual NIC for redundancy)
Storage	2 x 50 GB (50 GB minimum per Conferencing Node) 500 GB total per server (to allow for snapshots etc.) RAID 1 mirror for redundancy
Power	We recommend redundant power
Example 1U rack servers	HPE ProLiant DL360 Gen9 Dell R430/R630 Cisco UCS C220 M4 IBM x3550 M5 Supermicro 6018R-WTR dual E5 1U	HPE ProLiant DL360 Gen9 Dell R430/R630 Cisco UCS C220 M4 IBM x3550 M5 Supermicro 6018R-WTR dual E5 1U	HPE DL360p Gen8 Dell R620 Cisco UCS C220 M3 IBM x3550 M4 Supermicro 6017R-WRF
