The heat often leads to irregular air-flows within the data center and hot spots in a number of locations.
Also, the 1½- to 2-foot raised floor found in older data centers makes it difficult to provide and manage sufficient power for server and storage arrays.
For example, data centers originally designed for mainframe operations do not adapt well to large-scale implementation of blade servers, large Unix servers, concentrated storage and intense network activity.
The heat generated by the equipment is difficult to dissipate in an older data center, which typically has 12-foot ceilings.

The equipment and network requirements for synchronous or asynchronous data replication will constrain the use of a single backup site.
Server and storage virtualization help with this, but if physical configurations are not comparable, a price will be paid in capacity.When there are many data centers, the loss of one has limited effect.But if the number of disaster recovery sites is reduced, for example, from many to a relatively small number, the loss of any one of the DR facilities would be devastating.And there are few, if any, commercial disaster recovery services that can accommodate the new mega-data centers.Assuming that the decision to consolidate is made on the basis of a combination of technology, risk management, cost and customer service considerations, it is clear that recoverability requires a different approach than many companies have taken to disaster recovery in the past.Legacy data centers were designed for power loading of 35 to 45 watts per square foot, but keep in mind that highly concentrated equipment may draw up to 100 watts per square foot.
