organizations are seeing the benefit of using the two technologies together (see Figure 3).

Challenges and Inhibitors
While server virtualization is producing consistent benefits, it is also important to point out the vulnerabilities of
server virtualization. In the ―physical world,‖ if a server fails, the operating system and the installed application(s)
go offline. The same holds true in the ―virtual world,‖ but the significant difference is that the consolidation ratio
of multiple virtual machines running on a single physical server has the potential to greatly impact the operating
environment. In a virtual environment, all your eggs are in one basket. If a physical server fails, it will affect all of
the virtual machines and application interdependencies running on that particular piece of hardware. The
complexity of this scenario can quickly grow as more virtual machines are deployed and the organization
standardizes on server virtualization. The balance, however, is that a growing number of users are deciding that
the benefits far outweigh the challenges.

organization's deployment of storage virtualization technology
for use with its virtual server environment? (Percent of
respondents, N = 80)

the two
technologies
together, 53%
