1Server Hardware Requirements

 

 ConfigurationRequirement
Processor

Intel Xeon processors (Nehalem micro-architecture or above)

Note

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.

Note

The supported CPU

...

Family Number is 6 and CPU

...

Model Number must be newer than 26. Refer to Intel Architecture and Processor Identification document for more information.

 RAMMinimum 24 GB
Hard DiskMinimum 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).

Note

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.

Note

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

1VM Configuration Recommendations

 

Settings
 SettingsRecommended 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".
Note

3 vCPUs configuration is supported only from SBC 4.2.4 release.

Note

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
  • Use four different vSwitches for each vNICs on

    VM. This ensures various traffic to be physically separated on SBC.
    • Assign 1 physical NIC port (1 Gbps) to each vSwitch if physical NIC redundancy is not needed, otherwise assign 2 physical NIC ports (in active-standby mode using NIC team feature) to each vSwitch.

      Note

      The same physical NIC port cannot be associated with different vSwitches.

  • Use four different virtual networking labels, each with different VLANs or subnets.
  • Always run active and standby

    VMs on different physical servers
  • Disable VM logging
Note

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.
