For the past several years, companies of all sizes exploited this technology to arrest 
server sprawl associated with test/development, general IT workloads, and 
proliferating departmental reporting applications. The severe capital expense 
restrictions of 2009, along with improvements in the performance of multicore 
physical servers and the manageability of virtualized servers, spurred more 
aggressive and extensive use of server virtualization, including wide use in production 
environments. Based on current server sales and deployment patterns, 2009 will be 
the first year in which enterprises of all sizes and in all countries deploy more new 
application servers as virtual machines than as dedicated physical servers.  
Within a few short years, the vast majority (>70%) of new and upgraded server 
deployments will be virtual servers. Given the normal churn of applications, it is quite 
clear that nearly all data centers in large and midsize enterprises will comprise 
primarily virtualized servers by 2011. Less visible, but of equal importance, is that 
other IT assets such as storage, networks, and even some desktop environments will 
also be transitioning to a more virtualized foundation. The challenge for IT executives 
will be to manage this transition in a way that optimizes up-front and long-term 
hardware and facilities investments.

Transactional applications such as ERP, CRM, and OLTP that typically create and 
access structured data remain major consumers of new storage capacity; however, 
new applications and IT use cases are now more voracious consumers of storage 
capacity in many enterprises (see Figure 2).
