A great documentation set, the reference implementation guidance: Lab-tested and validated guidance for implementing multiple Microsoft products and technologies with hardware that meets specific, minimum, hardware vendor-agnostic requirements. Customers can use this guidance to implement a private cloud solution with hardware they already own or purchase.  The guidance set consists of the following downloadable documents:

• Reference Architecture Guide: This guide details a reference architecture that incorporates many Microsoft product and consulting team best practices.  The architecture is the foundation for a highly available, scalable, secure, and manageable private cloud with high performance.  While all organizations will find it of value, it will prove most useful to medium through large enterprise environments.
• Reference Deployment Guide: This guide provides detailed installation and configuration steps to deploy the physical architecture detailed in the reference architecture guide.
• Reference Operations Guide: This guide includes many of the operational tasks that are often executed in a private cloud environment
