Virtualization, a method for using software and hardware to make many separate storage devices appear as a single virtual device, is increasing in popularity across the enterprise for the purposes of server consolidation, as well as server flexibility and agility. This virtualization boom is making many integrators change their product mixes and strategies for addressing customer problems, partly because of the varying goals of companies even considering server virtualization.
With that in mind, we've collected some expert advice on combining both server and storage virtualization.
However, Schulz goes on to say in a book excerpt from Storage Virtualization: Technologies for Simplifying Data Storage and Management that "barriers to fully leveraging virtual servers, virtual storage and virtual networks may not be technology, but rather political and budget boundaries, as well as 'turf' wars within organizations." Improved resource usage and management can be realized by server, storage and network virtualization.
Wolf adds that it can be tough to meet backup window requirements following a server consolidation as a result of CPU, storage and network I/O contention among servers now forced to share physical devices. Storage resellers can alleviate backup and data protection problems by bundling storage virtualization and server virtualization as a single complementary solution, as outlined in the sidebar to the right.
