Virtualization: Don't stop with the "low-hanging fruit"

Everything, including Exchange, Oracle, and SAP servers, is fair game for virtualization.

Estimates are that only about 15 to 20 percent of IT resources that could be virtualized have been, meaning the market will continue to expand. Early adopters have paved the way, and no company should need education on the value of virtual servers today. Since the new buzz now is about VDI (Virtual Desktop Infrastructure), virtual desktops may become the norm rather than the exception in a few more years. After 10 years watching the virtualization market, Laverick says the business still feels as new and bleeding age as it did at the beginning.

A nice addition to vSphere4 and the vCenter 4.0 tools is a change to the vCenter DB retention policy. Before, the vCenter database grew day-by-day and week-by-week. There was no way to limit the size and set a point to start a First In First Out process to overwrite the oldest information with the newest. In vCenter 4.0, the vCenter Server Settings offer a retention policy time. Perhaps the vendors "borrowed" this idea from users, or on their own, but at least the vendors are expanding capabilities regularly. And with books like VMware vSphere 4 Implementation, you can expand your virtual capabilities.
