system may not behave as expected.

Server Hardware Requirements

Following table lists the server hardware requirements:

Server Hardware Requirements

ConfigurationRequirement
Processor

Intel Xeon processors (Nehalem micro-architecture or above)

It is recommended to use Westmere (or newer) processors for better SRTP performance. These processors have the AES-NI instruction set for performing cryptographic operations in hardware.

RAMMinimum 24 GB
Hard DiskMinimum 500 GB
Network Interface Cards (NICs)
Minimum 4 NICs.

Make sure NIC has multi-queue support which enhances network performance by allowing RX and TX queues to scale with the number of CPUs on multi-processor systems.

Ports

Number of ports allowed:

  • 1 Management port
  • 1 HA port
  • 2 Media ports

The

SBC SWe Requirements

For more information, see Downloading SBC SWe Installation Files from Salesforce Portal.

Make sure the Processors and VM configuration (CPUs, RAMs, Virtual Hard Disk, NICs, and bridge Settings) is identical for SBC SWe HA pair.

Make sure that the BIOS settings and recommendations must not be changed once it is applied on the server.
