Understanding the Split-Center Feature

This topic covers the vGW Series Split-Center feature that allows you to segment information contained in a single VMware vCenter into multiple independently managed vGW Series centers. The Split-Center feature allows for improved resource isolation for cloud services and multi-tenancy. It supports unlimited scalability as the VMware vCenter capacity increases.

You can use the Split-Center feature to segment a large vCenter into multiple management domains consisting of multiple data centers with each management domain managed independently by its own Security Design VM. A management domain can consist of one or more data centers. You can deploy as many vGW Security Design VMs as are needed as you scale your environment.

Overall, the individual vGW Security Design VMs associated with a vCenter secure all its ESX/ESXi hosts and VMs, but each individual vGW Security Design VM manages only a specific set of data centers. One vGW Security Design VM does not have visibility into another vGW Security Design VM or the parts of the virtualized environment that it secures. From the position of a single vGW Security Design VM, it is as if all objects outside the scope of the data centers that it manages do not exist.

To configure the Split-Center feature, you use the vCenter Scope selection menu called Select a scope for you Security Design vGW. An administrator can specify that he or she wants their vGW Security Design VM to manage all of the vCenter’s data centers, or they can select some of them.

As primary administrator, after you design how your virtualized environment will be managed using the Split-Center feature, tell the administrators of other vGW Security Design VMs which data centers they will manage. The vCenter displays all data centers as selections to all vGW Security Design VMs administrators.

Caution: When you configure the Split-Center feature, ensure that each data center is assigned to only one vGW Security Design VM. Otherwise, unexpected consequences can occur.
