Virtualization technologies -- for both storage and servers -- can help reduce the expense with unique approaches that differ from traditional DR methods and can provide increased flexibility and responsiveness. Server virtualization encapsulates an entire server into a single file, which makes transporting it to other locations much easier. Storage virtualization presents multiple storage devices as a single storage resource, which helps hide some of the back-end complexities of the storage devices and network.
