Server virtualization enables multiple operating systems to run on a single physical server as highly efficient virtual machines.Key benefits include: Greater IT efficiencies Reduced operating costs Faster workload deployment Increased application performance Higher server availability Eliminated server sprawl and complexity
In computer science, storage virtualization is "the process of presenting a logical view of the physical storage resources to a host computer system, "treating all storage media (hard disk, optical disk, tape, etc.) in the enterprise as a single pool of storage." A "storage system" is also known as a storage array, disk array, or filer. Storage systems typically use special hardware and software along with disk drives in order to provide very fast and reliable storage for computing and data processing. Storage systems are complex, and may be thought of as a special purpose computer designed to provide storage capacity along with advanced data protection features. Disk drives are only one element within a storage system, along with hardware and special purpose embedded software within the system.
Network virtualization is a method of combining the available resources in a network to consolidate multiple physical networks, divide a network into segments or create software networks between virtual machines (VMs).
