Host server components
The diagrams below outline the physical components of a host server, and shows how the components of a Pexip Infinity Conferencing Node virtual machine relate to these.
The table below provides descriptions for the terms used in the diagrams above and elsewhere in this guide, in the context of a Pexip Infinity deployment.
|Processor||The hardware within a computer that carries out the basic computing functions. It can consist of multiple cores.|
|Core||One single physical processing unit. Intel Xeon E5 typically has 8 cores (10, 12 or more in newer versions)|
|Socket||The socket on the motherboard where one processor is installed.|
||Also referred to as "memory modules". The hardware that stores data which is accessed by the processor core while executing programs.|
|Virtual CPU (vCPU)||
The VM's understanding of how many CPU cores it requires. Each vCPU appears as a single CPU core to the guest operating system.
When configuring a Conferencing Node, you are asked to enter the number of virtual CPUs to assign to it. We recommend no more than one virtual CPU per physical core, unless you are making use of CPUs that support hyperthreading; see Achieving additional performance with VMware NUMA affinity and hyperthreading for more details.
|NUMA node||The combination of a processor (consisting of one or more cores) and its associated memory.|
