Planning
There are two approaches to implementing virtual infrastructure - planning to succeed or failing to plan. Failing to plan doesn’t necessarily mean a failure to virtualize, but it nearly always means a much slower, haphazard, and painful path.
Virtualization is destined to have an enormous impact on IT – ranking right up there with the PC, network, and Internet. It provides an unparalleled opportunity for reducing:
+ Costs
+ Energy consumption
+ Time to deploy new servers/applications
+ Downtime
+ Management time
Virtualization is also a complex architecture, incorporating not only the servers, but the storage, backup, network, and DR environments. This complexity demands significant planning, and successful planning is dependent upon an accurate understanding of the existing physical environment.
