SBC SWe for KVM Hypervisor – Server Hardware Requirements

Multiexcerpt
MultiExcerptNameSBC SWe for KVM Hypervisor – Server Hardware Requirements

The following table lists the server hardware requirements.

Caption
0Table
1KVM Hypervisor Server Hardware Requirements

 

Configuration Requirement
Processor

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

Info
titleNote

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.

Info
titleNote

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.


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

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.

Info
titleNote

The Intel I350, x540, x550, and 82599 Ethernet adapters are supported for configuring as SR-IOV and DirectPath I/O pass-through devices.


Ports

Number of ports allowed:

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

Warning
titleWarning

The 

Spacevars

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

BIOS Setting Recommendations

Ribbon recommends the following BIOS settings for optimum performance:

SoftwareVersionTested or Qualified Version
KVM Module 3.10.0 or above3.10.0
QEMU Emulator  1.5.31.5.3

virt-manager0.10.00.10.0

Downloading the SBC SWe Software Package

For more information, see Downloading the SBC SWe Software Package.

Info
titleNote

Processors and VM configuration (CPUs, RAM, Virtual Hard Disk, NICs, and Bridge settings) must be identical for an SBC SWe HA pair.

Info
titleNote

BIOS settings and recommendations must not be changed once they are applied on the server.

KVM Configuration Recommendations 

Caption
0Table
1KVM Configuration Recommendations


 vCPU

Minimum 4 vCPUs required. Any number of vCPUs may be configured depending upon the call capacity requirements, but the number should be even (4, 6, 8, etc.) to avoid impacting performance.  

 vRAM

Reserve the memory based on call capacity and configuration requirements. Refer to benchmarking data for supported call capacities with different configuration limits.

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).

 

Note: Hard disk size cannot be changed after the SBC SWe software is installed.

vNICs

Set number of virtual NICs as 4 (1-MGMT, 1-HA, 1-PKT0 and 1-PKT1).

  • Use only Virt-IO driver.
  • Associate each vNIC to separate bridges.



Info
titleNote
  • Processors, KVM hypervisor version and VM configuration (vCPUs, vRAM, Virtual Hard Disk, vNICs, and vSwitch Settings) must be identical for an SBC SWe HA pair.
  • BIOS and KVM hypervisor settings and recommendations must not be changed once they are applied on the server.
