Managing Your System Capacity

System Capacity

The base deployment models are micro (50), small (250), medium (800) and large (2000). You can extend the system capacity of a large deployment from 2000 up to 4000 ports. You can reduce the capacity of an extended system deployment, down to the base large deployment of 2000 ports.

To extend or reduce the system capacity, you add or remove up to 3 extension units. Each unit of growth consists of the following components:

One media
One web
One IRP (only if public access is enabled)

Note

Each extension unit adds up to 700 more ports, up to the maximum 4000 ports for the system. When you add 3 extension units, you double the system capacity by adding 700 + 700 + 600 ports.

The Extended Capacity feature requires a license. For more information, contact your Cisco Account Manager.

Recommended Blade Allocation

Adding 3 extension units doubles the system capacity and the hardware requirements. The blade allocation pattern follows that of a large system. With an extended system, you can allocate 2 IRPs to a single blade.

Important

Because IRP2 is the backup load balancer, do not allocate IRP2 to the same blade as IRP1 (from the base system).

Table 1. Blade Allocation
Blade 1	Admin	Media
Blade 2	Media	Web
Blade 3	Media	Web
Blade 4	IRP 1	IRP 3 *
Blade 5 *	IRP 2 *	IRP 4 *
Blade 6 *	Media *	Web *
Blade 7 *	Media *	Web *
Blade 8 *	Media *	Web *

Extending System Capacity

You extend the system capacity by adding up to 3 extension units of virtual machines.

Before you begin

Obtain the base version Open Virtualization Archive (OVA) file that was used to install the system. For example, if the initially deployed version is 3.0, obtain the base 3.0 OVA.

Important

Create a backup before you proceed with this system-altering procedure.

Schedule a maintenance window and notify users about the scheduled system maintenance time. For more information, see the "Related Topics" section for this procedure.

Procedure

Step 1	Sign in to Webex Site Administration. In a Multidata Center system, the DNS determines which data center Dashboard appears. Use this Dashboard to manage all the data centers in this system.
Step 2	Turn on Maintenance Mode. Turning on Maintenance Mode for all active data centers shuts down all conference functionality. No one can sign in to the Webex site, schedule meetings, join meetings, or play meeting recordings. If the data center is part of a Multidata Center (MDC) system, in-progress meetings fail over to an active data center. The failover can cause a brief interruption in active meetings.
Step 3	Go to the System tab, and then click Manage.
Step 4	On the Manage System Specifications page, click the Manage System Capacity radio button, and then click Continue.
Step 5	On the Manage System Capacity page, click the Extend system capacity radio button, and then click Continue.
Step 6	Click Add 700 Ports to add an extension unit. Each time you add an extension unit, a set of new fields (for the media, web, and IRP virtual machines) appears. You can repeat this step again until you reach the maximum capacity of 4000 ports.
Step 7	Enter the fully qualified domain names for the new virtual machines, and then click Add virtual machines.
Step 8	When the process is complete, click Done. Depending on the CWMS version of the newly added virtual machines, the system can require a restart.
Step 9	Turn off Maintenance Mode.

Reducing System Capacity

You reduce system capacity by removing extension units of virtual machines.

Step 6	From the drop-down lists, select the fully qualified domain names for the media, web, and IRP virtual machines that you want to remove.
Step 7	(Optional) To remove another extension unit, click Add new group for VM removaland then select the FQDNs for the VMs to remove.
Step 8	Click Remove virtual machines.
Step 9	When the process is complete, click Done.
Step 10	Turn off Maintenance Mode.
