This section describes SBC SWe hardware and software requirements and recommendations.

To install and configure SBC SWe, make sure the Virtual Machine (VM) host meets the following recommended hardware, server platform and software requirements.


The recommended hardware and software settings are intended to ensure optimum SBC SWe stability and performance. If the recommended settings are not used, the SBC SWe system may not behave as expected.

SBC SWe for VMware – Server Hardware Requirements

The following table lists the server hardware requirements:

Table : Server Hardware Requirements


Intel Xeon processors (Nehalem micro-architecture or above) with 6 cores and above (processors should support hyper threading).


Ribbon recommends using Westmere (or newer) processors for better SRTP performance. These processors have the AES-NI instruction set for performing cryptographic operations in hardware.


The supported CPU Family number is 6 and CPU Model number must be newer than 26. Refer to the Intel Architecture and Processor Identification document for more information.


ESXi 6.5 and later releases require approximately 2 physical cores to be set aside for hypervisor functionality. The number of VMs which can be hosted on a server must be planned for accordingly.

 RAMMinimum 24 GB
Hard DiskMinimum 500 GB
Network Interface Cards (NICs)
Minimum 4 NICs, if physical NIC redundancy is not required.

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

  • The following NICs are supported for configuring as SR-IOV and DirectPath I/O pass-through devices. SR-IOV is supported only with 10 Gbps interfaces (x540/82599/x710):

Intel I350, x540, x550, x710 and 82599, Mellanox Connect - 4x, Mellanox Connect - 5x, and CISCO VIC. 

  • The VMware Enterprise Plus license is required for SR-IOV.

Number of ports allowed:


The SBC SWe software only runs on platforms using Intel processors. Platforms using AMD processors are not supported.

SBC SWe for VMware – Software Requirements

The following are the SBC SWe requirements for VMware ESXi environments:
