Understanding the Multi-Center Feature

This topic covers the vGW Series Multi-Center feature that synchronizes policy across vGW Series management centers to enable large scale virtualization. This topic includes the following sections:

The Multi-Center Feature

For various reasons–such as geographic separation of data centers, scaling requirements, and use of different administrative domains–some companies who deploy the vGW Series must use more than one VMware vCenter to manage their environments. These companies want to use the same or similar vGW Security Design VM configuration for all of their data centers, as if they were rolling out a single deployment. Manually configuring separate vGW Security Design VMs at various locations with the same information consumes time, is cumbersome, and is error prone.

To accommodate companies with these requirements and companies that want to scale their environments for other reasons, the vGW Series includes a feature called Multi-Center. The Multi-Center feature allows you to designate a vGW Security Design VM connected to a vCenter at one location as the master.

Following the database replication model, configuration is done at master vGW Security Design VM. It can be synchronized to one or more delegate vGW Security Design VM centers, each of which is connected to an individual vCenter. Configuration of global objects at the master vGW Security Design VM is propagated to the delegate vGW Security Design VMs centers automatically, based on objects selected when the administrator of the master vGW Security Design VM creates a Multi-Center definition for the delegate center.

Deploying vGW Series to Include Delegate and Stand-alone vGW Security Design VMs

You can deploy your virtualized environment to include vGW Security Design VMs that participate in the Multi-Center feature configuration and those that do not. You might want one vGW Security Design VM that manages resources at a specific vCenter to have a unique configuration and others at different vCenters to use largely the same configuration.

Consider a virtualized environment that includes six data centers of various sizes, each of which is connected to an individual vCenter. You determine that you must use the same overall configuration for five of the data centers, but not for the sixth one. In this case, you can use the Multi-Center feature for the five data centers that must be configured similarly, but configure the sixth vGW Security Design VM separately.
