Prerequisites for installing Pexip Infinity

This section lists the prerequisites for installing the Pexip Infinity version 11 platform.

There are further requirements for deploying the complete platform in your network. For more information, see Pexip Infinity installation overview.

Host servers

The following table lists the recommended hardware requirements for the Management Node and Conferencing Node host servers.

	Management Node	Conferencing Node
Server manufacturer	Any	Any
Processor make*	Any	Intel Xeon E5-2600 series (Haswell architecture) or similar Xeon processors from 2012 or later
Processor instruction set	Any	AVX2^‡
Processor architecture	64-bit	64-bit
Processor speed	2.0 GHz	2.3 GHz or faster
No. of physical cores*	2^†	10-12 cores per socket
Processor cache	no minimum	20 MB or greater (2.5 MB L3 cache per core)
Total RAM*	4 GB^†	1 GB per core
RAM makeup	Any	All channels must be populated with a DIMM.
Hardware allocation	The host server must not be over-committed in terms of either RAM or CPU. In other words, the Management Node and Conferencing Nodes each must have dedicated access to their own RAM and CPU cores.
Storage space required	100 GB	50 GB per Conferencing Node
GPU	No specific hardware cards or GPUs are required.
Network	Gigabit Ethernet connectivity from the host server.
Operating System	The Pexip Infinity VMs are delivered as VM images (.ova etc) to be run directly on the hypervisor. No OS should be installed.
Hypervisor	VMware ESXi 4.1, 5.x or 6.0 Microsoft Hyper-V 2012 or later Xen 4.2 or later KVM (Linux kernel 3.10.0 or later, and QEMU 1.5.0 or later)
* This does not include the processor and RAM requirements of the Hypervisor. ‡ For VMware platforms, ESXi 6 is required to make full use of the AVX2 instruction set. Note that AVX and SSE4.1 are also supported. † Sufficient for deployments of up to 30 Conferencing Nodes. For larger deployments, you will need to increase the amount of RAM and number of cores. For more information about our server design guidelines, consult your Pexip support representative.

For further information, see the Server design guidelines.

Hypervisors

Pexip Infinity currently offers specific support for VMware ESXi, Microsoft Hyper-V, KVM and Xen hypervisors. Other hypervisors and orchestration layers may be used but are not officially supported. If you wish to deploy Pexip Infinity using a non-supported hypervisor, we recommend that you contact your authorized Pexip representative for assistance.

For details on installation using a specific hypervisor, refer to the following sections:

Network requirements

Note that in all Pexip Infinity deployment scenarios:

All Pexip nodes must be fully routable to each other (full mesh) in both directions. This means that the Management Node must be able to reach every Conferencing Node, and each Conferencing Node must be able to reach every other Conferencing Node.
Any internal firewalls must be configured to allow UDP port 500 and traffic using IP protocol 50 (ESP) in both directions between all Pexip nodes.
There cannot be a NAT between any Pexip nodes.
