Three forces are shaping the future evolution of the modern data center: 

 

Wholesale virtualization/consolidation of server, storage, and network 
environments within (the virtualized data center) 

 

Diversification of information sources and data management requirements (the 
information-rich data center) 

 

Optimization of IT system deployment (the efficient data center) 

In combination, these three developments are reshaping how enterprises architect 
and acquire their core IT assets (servers, storage, and networks). They are also 
affecting the way IT organizations manage and introduce new capabilities into their 
data centers. They can't afford the time and effort associated with large scale "forklift" 
upgrades. Instead, they require solutions that make it easier to introduce new 
security, information management, and business continuity capabilities without 
disrupting existing systems and operations.  

 

The most visible technological transition in today's enterprise data center is the 
widespread adoption of server virtualization as part of major server consolidation 
efforts. With the economic difficulties of 2009, this transition is crossing a critical 
threshold (see Figure 1).
