Virtual data storage refers to the software that abstracts the physical locations of info on different hardware arrays into a rational view pertaining to application access. The aim is to get rid of the dependency among where the data is seen and in which it is bodily stored, streamlining day to day business such as going storage to a new site or increasing the capacity of existing hard disk drives without disrupting access. There are many types of virtual storage space software solutions which range from simple record systems to advanced array level virtualization that offer most of the same benefits as host based level management.
Unlike basic solo hard disk drives, most disk arrays already furnish some form of virtualization by using REZZOU schemes to combine multiple physical disks into one logical device that click this site can be partitioned later. Heightened arrays typically include cloning and distant replication products. However these kinds of array established solutions are limited about what they can do as they depend on the safe-keeping controller to accomplish the virtualization.
Safe-keeping virtualization supplies the next degree of abstraction that allows storage equipment to be pooled together as being a single reasonable system that can be monitored independently from other units in a network or in a data center. This is a lot like how figure out virtualization (VMWare ESX or perhaps Hyper-V) abstracts the physical compute hardware into a reasonable view. Occasionally, storage virtualization can even combine unlike components from multiple networks and vendors into a single pool meant for easier operations.
