|
...
The following table lists the server hardware requirements |
...
...
| Table | | 1 | KVM 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) |
|
...
Westmere (or newer) processors are recommended 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. |
|
...
| Info |
|---|
| 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
|
|
| Warning |

Downloading the SBC SWe
...
...
Processors and VM configuration (CPUs, RAMs, Virtual Hard Disk, NICs, and bridge Settings) |

BIOS settings and recommendations must not be changed once it is applied on the server. |
KVM Configuration Recommendations
| Caption |
|---|
| 0 | Table |
|---|
| 1 | 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 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 |
|---|
|
- Processors, KVM hypervisor version and VM configuration (vCPUs, vRAMs, Virtual Hard Disk, vNICs, and vSwitch Settings) must be identical for SBC SWe HA pair.
|
...
- settings and recommendations must not be changed once it is applied on the server.
