Storage Virtualization: Technologies for Simplifying Data Storage and Management By Tom Clark, What is storage virtualization Definition from WhatIs Aug , Array based storage virtualization most commonly refers to the method in which a storage array presents different types of physical storage for use as storage tiers How much of a storage tier is made up of solid state drives SSDs or HDDs is handled by software in the array and is hidden at the guest machine or user level. Storage Virtualization Computerworld With storage virtualization, large numbers of physical resources are viewed as a single resource, which helps automate tasks such as backup and recovery Read about the technology s history and Storage virtualization 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. Pros and cons of storage virtualization technologies Aug , Storage virtualization technologies include software based, appliance based and switch based approaches, each with its advantages and disadvantages There are also hybrid approaches that combine storage virtualization with other technologies, like standard storage switching Storage virtualization crops up in various places. Storage virtualization technology benefits and drawbacks Nov , Managing multiple storage devices can be difficult and time consuming, so many IT managers turn to storage virtualization technology for data storage management Storage virtualization can hide the complexity of a storage area network SAN by pooling together multiple storage devices so they look like they re just one storage device. Storage Virtualization A Deep Dive DataCore Software A storage virtualization node is essentially a virtual controller that virtualizes and manages your physical storage All your disk arrays are placed inside a virtual pool and thin provisioned for
