Older physical systems take a disproportionate amount of management attention and suffer from replacement parts becoming extremely expensive and slow to be delivered. Typically these systems are running on Sun, Windows NT and even Windows 2000. In order for IT to meet the demands of the business, IT needs to propel the infrastructure forward by adding features and capabilities. Having legacy systems in the general infrastructure with dependencies on their surrounding environment complicates almost all infrastructure improvement projects.
Moving these systems into “a box” that can be turned on when needed would be beneficial. But as long as the legacy systems still have dependencies, simply segmenting, virtualizing or working around them isn’t a viable solution. Building a virtual storage area segmented from the network will require much more than a stack of Qualified virtual servers. In addition, access without bi-directional technology pollution, authentication synchronization, and unsupported vendor applications and platforms further complicate matters.
