system may not behave as expected.
SBC SWe for KVM Hypervisor – Server Hardware Requirements
The following table lists the server hardware requirements.
KVM Hypervisor Server Hardware Requirements
Configuration | Requirement |
---|
Processor | Intel Xeon processors (Nehalem micro-architecture or above) Note: Sonus recommend using 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. 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. |
Ports | Number of ports allowed: - 1 Management port
- 1 HA port
- 2 Media ports
|
The

software runs only on platforms using Intel processors. Platforms using AMD processors are not supported.
BIOS Setting Recommendations
Sonus recommends the following BIOS settings for optimum performance:
Recommended BIOS Settings for Optimum Performance
BIOS Parameter | Recommended Setting | Details |
---|
Intel VT-x (Virtualization Technology) | Enabled | For hardware virtualization |
Intel Hyper-Threading | Enabled | |
Intel Turbo Boost | Enabled | |
CPU power management | Maximum Performance | |
For example, the BIOS settings are shown below for HP DL 380p Gen8 servers. For BIOS settings of other servers, refer to the respective vendor's website.
BIOS Setting Recommendations for HP DL380p Gen8 Server
BIOS Parameter | Recommended Setting | Default Value |
---|
HP Power Profile | Maximum Performance | Balanced Power and Performance |
Thermal Configuration | Maximum Cooling | Optimal Cooling |
HW Prefetchers | Disabled | Enabled |
Adjacent Sector Prefetcher | Disabled | Enabled |
Processor Power and Utilization Monitoring | Disabled | Enabled |
Memory Pre-Failure Notification | Disabled | Enabled |
Memory Refresh Rate | 1x Refresh | 2x Refresh |
SBC SWe for KVM Hypervisor – Software Requirements
Following are KVM hypervisor and SBC SWe software requirements:
Software | Version | Tested or Qualified Version |
---|
Red Hat Enterprise Linux | 7.0 or above | 7.0 |
KVM Module | 3.10.0 or above | 3.10.0 |
QEMU Emulator | 1.5.3 | 1.5.3 |
libvirtd (libvirt) | 1.1.1 | 1.1.1 |
virt-manager | 0.10.0 | 0.10.0 |
Downloading the SBC SWe Software Package
For more information, see Downloading SBC SWe Installation Files from Salesforce Portal.
Processors and VM configuration (CPUs, RAMs, Virtual Hard Disk, NICs, and bridge Settings) must be identical for SBC SWe HA pair.
BIOS settings and recommendations must not be changed once it is applied on the server.
KVM Configuration Recommendations
KVM Configuration Recommendations
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. KVM Direct-IO mode is only supported for PKT ports for vCPUs >=4. |
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.
|
- Processors, ESXi version and VM configuration (vCPUs, vRAMs, Virtual Hard Disk, vNICs, and vSwitch Settings) must be identical for SBC SWe HA pair.
- BIOS and ESXi settings and recommendations must not be changed once it is applied on the server.
