Proof of concept

Testing the consolidation steps on a smaller number of servers provides an overview of the issues involved and how the process would work. In the configurations presented in this chapter, four servers are consolidated into one or two servers. The first configuration, which consolidates four smaller servers to one large server, provides fault tolerance through mirroring. In the second configuration, clustering and DMP are added to improve the fault tolerance, and an additional server is needed to support clustering. New, larger, more powerful servers can be used in this proof of concept testing. Once the concept is tested, the main task is to migrate the data from the production servers to the new larger servers.
