Overview
Demand to store more data for longer periods of time is driving the need for more data storage capacity, which in turn drives energy consumption and consequent cooling demands. This chapter looks at various data storage technologies and techniques used to support data growth in an economical and environmentally friendly manner. These technologies also aid in sustaining business growth while building on infrastructure resource management functions, including data protection, business continuance and disaster recovery (BC/DR), storage allocation, data movement, and migration, along with server, storage, and networking virtualization topics. Although this chapter focuses on external direct attached and networked storage (either networked attached storage or a storage area network), the principles, techniques, and technologies also apply to internal dedicated storage. The importance of this chapter is to understand the need to support and store more data using various techniques and technologies to enable more cost-effective and environmentally as well as energy-friendly data growth.

In this chapter you will learn that:

• An expanding data footprint results in increased management costs and complexity.
  
• Data storage management is a growing concern from a green standpoint.
  
• There are many aspects of storage virtualization that can help address green challenges.
