Architecture Overview

1.1 BCDR Solution Conceptual Design

The solution to support BCDR of the workloads running on VMware vSphere contains various components that must be integrated to make them work well together. These components range from networking devices, infrastructure services, and storage area network (SAN) devices to vSphere and applications. Each of these components has a large number of

potentially valid configurations, but only a few of these configurations result in an integrated, functional system that meets the specified business and technical requirements.

The service management and operations processes affected by the BCDR solution are out-of-scope for this engagement and are not addressed in this document.

The following figure illustrates the conceptual design for the solution.

Replace the diagram with an updated version that reflects the customer’s requirements. Use the Layers option in Visio to remove components that will not be deployed.
