Performance capabilities
The performance capabilities of Expressway X8.5 software are summarized below. In all cases, note that:
n
You can cluster up to 6 Expressways to increase capacity. This offers N+2 redundancy, because the
maximum capacity of a cluster is 4 times the physical limit of a single Expressway.
maximum capacity of a cluster is 4 times the physical limit of a single Expressway.
n
Logging is at default levels.
n
Performance capacity will be reduced by features such as TURN relay services, and by configuring large
numbers of zones and search rules.
numbers of zones and search rules.
n
VM hardware requires a minimum of 6GB RAM.
n
The Expressway supports up to 500 concurrent searches.
CE1000 appliances or Large VM servers (minimum 8 cores with 2 x 10Gb NIC)
Supports 500 encrypted traversal calls @ 768kbps or 1000 encrypted SIP audio traversal calls @ 64kbps,
and 500 non-traversal calls.
and 500 non-traversal calls.
This assumes a maximum sustained call rate of 10 calls per second.
CE500 appliances or Small/Medium VM servers (2 cores and 1Gb NIC)
Supports 100 encrypted traversal calls @ 768kbps and 500 non-traversal calls.
This assumes a maximum sustained call rate of 5 calls per second.
