1. Maximize Physical Space Efficiently
This often takes the form of consolidation. Consolidation encompasses not just large, glass-house facilities, but also small server clusters and wiring closets. If there are too many data centers supporting the organization, they add unnecessary cost, are less controllable and lead to power inefficiencies. Also, small facilities suck up power unnecessarily, tie up inventory and burn cash out of an IT organization’s budget.

2. Maximum Server Efficiency Through Virtualization
Virtualization is a fast spreading concept. Virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console. Storage virtualization helps the storage administrator perform the tasks of backup, archiving, and recovery more easily, and in less time, by disguising the actual complexity of the storage area network (SAN). Its benefits extend beyond merely improving the efficiency and usage ratio for central servers and storage systems. They also include faster provisioning of new projects, applications or users, as well as greater reliability and business continuity thanks to fast replication of virtual machines as backups.

3. Utilizing External Cloud Computing
A number of organizations are migrating select applications, mainly e-mail and other utilitarian functions, to cloud environments run by third parties. That frees up staff and infrastructure for more mission-focused work such as application development.

4. If It Provides Flexibility, Deploy Internal Clouds
To support a wide range of users and services with easy scalability and rapid provisioning, many organizations have launched their own cloud computing infrastructures. Internal cloud strategies force a rethinking of hardware architectures, utilizing consolidated, converged or data-center-in-a-box approaches.

5. Optimized Power Use
New form factors, mainly blade servers and converged infrastructures, need up-to-date cooling strategies. Instead of simply chilling the interior of an entire facility, the latest cooling technologies focus concentrated cooling where and when it is specifically needed within racks and aisles to radically reduce cooling costs.
