Scalability and Capacity
|
Single VCS capacity (appliance or small and medium virtual-machine deployments)
|
● The capacity of one Cisco VCS (appliance or small and medium virtual machine) follows:
◦ Up to 2500 registrations
◦ Up to 500 nontraversal calls
◦ Up to 100 traversal calls
◦ Up to 1000 subzones
|
Single VCS capacity (large virtual-machine deployments)
|
● The capacity of one Cisco VCS (large virtual machine) follows:
◦ Up to 2500 registrations
◦ Up to 500 nontraversal calls
◦ Up to 500 traversal calls
◦ Up to 1000 subzones
|
Cisco VCS CE500 Appliance
|
● The capacity of one Cisco VCS CE500 is as follows:
◦ 1 Gbps network interface
◦ Up to 2500 registrations
◦ Up to 500 nontraversal calls
◦ Up to 100 traversal calls
◦ Up to 1000 subzones
Note: The maximum number of calls interworked to Microsoft Lync is 100. It is highly recommended that a separate Cisco VCS Control be deployed for use as a dedicated Microsoft Lync gateway.
|
Cisco VCS CE1000
|
● The capacity of one Cisco VCS CE1000 is as ffollows:
◦ 1 or 10 Gbps network interfaces
◦ Up to 2500 registrations
◦ Up to 500 nontraversal calls
◦ Up to 500 traversal calls
Note: The maximum number of calls interworked to Microsoft Lync 2013 is 100. It is highly recommended that a separate Cisco VCS Control be deployed for use as a dedicated Microsoft Lync gateway.
|
Clustered VCS capacity
|
● Up to six VCS appliances or virtual machines can be clustered to increase capacity and provide redundancy.
● Clustering increases the maximum registrations, traversal, and nontraversal calls by up to four times.
|
Microsoft Lync interworking capacity
|
● The maximum number of calls interworked to Microsoft Lync is 100. It is highly recommended that a separate VCS Control server is deployed for use as a dedicated Microsoft Lync gateway.
