What Is a Reference Architecture?

As it relates to storage, a reference architecture is typically a document that identifies and describes the various components in your storage environment. It delineates the resources in use, states their purpose, and discusses their relationship with each other. The documentation is usually a series of tables, illustrations, and an accompanying narrative. Reference architecture should discuss the use of best practices in your infrastructure to help you meet your objectives.

Developing and maintaining a reference architecture provides a number of benefits. The information contained in the Reference Architecture is key to planning -- it puts ink on paper and provides a vehicle for discussion and communication. This is particularly valuable when communicating with vendors about how your environment is put together. Your reference architecture aids in maintaining consistency and demonstrates compliance with your IT governance.

If you don't have a reference architecture, I recommend putting one together. It will save you time and money in the long run.
