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. 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:
|
The

software only runs 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 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 |
Software Requirements
Following are KVM hypervisor and SBC SWe software requirements:
KVM Requirements
KVM 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 |
SBC SWe Requirements
For more information, see Downloading SBC SWe Installation Files from Salesforce Portal.
Make sure the Processors and VM configuration (CPUs, RAMs, Virtual Hard Disk, NICs, and bridge Settings) is identical for SBC SWe HA pair.
Make sure that the BIOS settings and recommendations must not be changed once it is applied on the server.
