system may not behave as expected.
Server Hardware Requirements
Following table lists the server hardware requirements:
Server Hardware Requirements
Configuration | Requirement |
---|
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.
|
RAM | Minimum 24 GB |
Hard Disk | Minimum 500 GB |
Network Interface Cards (NICs) | Minimum 4 NICs, if physical NIC redundancy is not required. Otherwise, 8 NICs (preferably with SR-IOV capability to support future SWe optimizations).
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.
Only Intel I350 Ethernet adapter is supported for configuring as VMDirectPath I/O pass-through device.
|
Ports | Number of ports allowed: - 1 Management port
- 1 HA port
- 2 Media ports
|
The

VM Configuration Recommendations
VM Configuration Recommendations
Settings | Recommended Configuration |
---|
vCPU | Minimum 4 vCPUs required. But In case where there are only four physical cores available, you must configure the VM with only 3 vCPUs. Any number of vCPUs may be configured depending upon the call capacity requirements. - Keep Resource Allocation setting marked as 'unlimited' with CPU freq. set to "physical processor CPU speed multiplied by number of vCPUs assigned to VM".
3 vCPUs configuration is supported only from SBC 4.2.4 release.
VMDirectPath mode is only supported for PKT ports for vCPUs >=4.
|
vRAM | Keep Resource Allocation setting marked as 'unlimited'. Reserve the memory based on the VM capacity requirement. For lesser than 6K calls, the minimum reservation must be 8GB. Anything higher than 6K calls requires atleast 14 GB vRAM. |
Virtual Hard Disk | Set Hard Disk (virtual) size as 100 GB or more (based on requirements of retaining CDRs, logs, etc. for number of days) - Use Thick provisioning (eager zero)
- Hard disk size cannot be changed once SBC SWe software is installed
|
vNICs | Set number of virtual NICs as 4 (1-MGMT, 1-HA, 1-PKT0 and 1-PKT1). - Use only VMXNET3 driver
Always use automatic MAC address assignment option while creating vNICs. Associate each vNIC to separate vSwitches Use ESXi NIC teaming feature to achieve redundancy at physical NIC level.
|
vSwitch settings | |
Make sure the Processors, ESXi version and VM configuration (vCPUs, vRAMs, Virtual Hard Disk, vNICs, and vSwitch Settings) must be identical for SBC SWe HA pair.
Make sure that the BIOS and ESXi settings and recommendations must not be changed once it is applied on the server.
