Notes on Expressway VM configurations
Cisco Expressway on the Cisco Business Edition 6000 requires only 4GB memory.
vDisk 1 = 4 GB, vDisk 2 = 128 GB.
Large VM configuration requires 10Gb NIC and the host CPU must support the AES-NI instruction set (and it must not be masked by ESXi).
Testing was performed on a Cisco UCS C220 M3S platform. Based on evidence from this testing we do not expect there to be any issues with other supported hardware options.
For more information, see Cisco Expressway on Virtual Machine Installation Guide.
IOPS and Storage System Performance Requirements
This section provides the IOPS data for a Cisco Expressway system under load.
| Activity|| Average IOPS|| Average r/w latency|| Peak read latency|| Peak write latency|
| Performance test*|| 5|| 0.5ms|| 15ms|| 2ms|
| Software upgrade|| 35|| 5ms|| 300ms|| 160ms|
| Core dump|| 40|| 10ms|| 100ms|| 10ms|
| Burnin test suite|| 35|| 50ms|| 400ms|| 60ms|
* Performance test comprised 100 simultaneous interworked and encrypted calls at 768kbp/s
Note that Cisco VCS software X7.2 and later takes advantage of AES acceleration on Intel Advanced Encryption Standard New Instruction set available on the Cisco C2xx family of servers. This provides enhanced performance for encrypted calls.
