You're knee-deep in virtualization, and you love the ROI that you've seen so far. But you're also grappling with tough technical and political challenges posed by today's hottest technology, according to CIO's first survey on virtualization.
The top challenges? First, figuring out just how far you can push your physical servers by piling on more and more virtual machines (VMs) without slowing down application service levels, and next, getting experts from across IT silos to plan and manage the virtualized environment together. "Nobody likes change, even when there is often a better way of doing things," says Stephen Elliot, a research manager with IDC (a sister company to CIO.com's publisher). "It takes work and a mindset to reinvent IT and ourselves."
The good news: The payback on virtualization really pops. Server virtualization, in particular, is spreading a lot of love; so far, happiness is harder to come by on the desktop.
Here's what nearly 300 CIOs who responded to the survey shared about their experiences to date with the virtualization mega-trend, along with forward-looking advice to help you make the most of virtualization efforts in the year ahead (Numbers on some tables may not add to 100 percent due to rounding).

Masters of Virtual Disaster Recovery
In addition to the obvious cost-cutting benefits, a desire for better disaster recovery plans drives many CIOs to adopt virtualized servers. IT leaders like Vincent Biddlecombe, CTO of logistics provider Transplace, use VMs to copy their production servers to disaster recovery facilities. As for flexibility and speed, Biddlecombe can provision a new server in 30 minutes instead of a week. When a Transplace business executive needs a new customer demonstration environment, IT can do in half an hour.
