This section describes the hardware and software requirements for SBC SWe Cloud on an OpenStack platform.

OpenStack Requirements

The SBC SWe supports the following OpenStack environments:

  • Newton with RHOSP 10 and RHEL 7.4
  • Queens with RHOSP 13 and RHEL 7.5
Note

The SBC SWe Cloud was tested on OpenStack Queens with RHOSP 13 and RHEL 7.5.

Server Hardware Requirements

 
ConfigurationRequirement
Processor

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

Note

Ribbon recommends Westmere (or newer) processors for better SRTP performance. These processors have the AES-NI instruction set for performing cryptographic operations in hardware. 

 RAMMinimum 24 GiB
 Hard DiskMinimum 100 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.

Note

The PKT ports must be 10 Gbps SR-IOV enabled port.

Note

6 NICs are required for supporting PKT port redundancy.

Note

To configure VLAN on SRIOV and PCI Passthrough Ethernet interfaces, disable the Data Center Bridging (DCB) on the switch connected to the interfaces.

 

The system hosting the SBC SWe must meet the following requirements to achieve the performance targets listed: 

S-SBC SWe Requirement

S-SBC SWe Requirements
for 1000 CPS/120K Signaling Sessions 		Notes

32 vCPUs

Due to the workload characteristics, allocate 20 physical cores with two hyper-threaded CPUs from each core to the SBC.

128 GiB RAM

Must be Huge Page memory. The minimum page size is 2048 KiB, but 1048576 is recommended.

100 GB Disk

None

4 vNICs/6 vNICs

Attach MGT0 port to the Management VirtIO Tenant network.

HA port has to be on IPv4 VirtIO Tenant network.

Attach PKT0 and PKT1 ports to SR-IOV and Provider network.

You must require 6 vNICs for enabling PKT port redundancy. For more information, refer to SBC SWe Cloud Features Guide.

Note

All NIC ports must come from the NUMA node 0. The S-SBC SWe instance is hosted on dual-socket physical server with 10 physical cores coming from each NUMA node.

M-SBC SWe Requirement

M-SBC SWe Requirements
for 30K Media Sessions		Notes

20 vCPUs

Due to the workload characteristics, allocate 10 physical cores with two hyper-threaded CPUs from each core and from single NUMA node to the SBC.

32 GiB RAM

Must be Huge Page memory. The minimum page size is 2048 KiB, but 1048576 is recommended.

100 GB Disk

None

4 vNICs/ 6 vNICs

Attach MGT0 port to the Management VirtIO Tenant network.

HA port has to be on IPv4 VirtIO Tenant network.

Attach PKT0 and PKT1 ports to SR-IOV and Provider network.

You must require 6 vNICs for enabling PKT port redundancy. For more information, refer to SBC SWe Cloud Features Guide.

Note

All NIC ports must come from the same NUMA node from which the M-SBC SWe instance is hosted.
