Storage virtualization works by creating an abstract layer between the OS and the underlying physical disks. The storage virtualization program will create a virtual logic space that will be mapped to each and every drive in the physical memory. When users seek control, they seek it through this logic layer, unknown that there are several underpinning storage devices.
When should storage virtualization be used?
Storage virtualization can be used for a number of things, given the advantages it has over normal storage. Some common uses include –
· For creating more than one storage arrays
· For smoothening data flow
· For enhancing data accessibility
What is the need of storage virtualization?
Storage virtualization can help administrators to backup, restore and manage data more efficiently and smoothly than traditional data. A single organization can have data stored in several hundred servers and so managing each and every storage component can be an issue. Restoring data from individual disks can be a nightmare in itself. This is where storage virtualization can help administrators. It allows for easy management of data from one place.
