IBM PowerVM Virtualization
Complexity can work its way into your
IT infrastructure, driven by the introduc-
tion of new applications and unantici-
pated growth. However, adding a
server each time you have new demand
for a new application means that you
also require additional floor or rack
space, power, cooling, network inter-
faces, data storage and administrative
resources. Such complexity leads to
inefficiency.
The answer is consolidation and virtual-
