What is Virtual Data Storage?

Virtual data storage refers to the software that abstracts the physical locations of data on numerous hardware arrays into a rational view with respect to application get. The target is to eliminate the dependency between where the data is used and in which it is physically stored, streamlining day to day business such as going storage into a new location or advancing the capacity of existing hard disk drives without disrupting access. There are numerous types of virtual storage software solutions including simple data file systems to advanced mixture level virtualization that offer most of the same benefits as number based level management.

Unlike basic sole hard disk drives, most disk arrays already provide some form of virtualization by using RAID schemes to mix multiple physical disks into one logical unit that can be partitioned later. More complex arrays typically include cloning and remote control replication offerings. However these kinds of array based upon solutions happen to be limited in what they can carry out as they depend on the safe-keeping controller to do the virtualization.

Storage virtualization supplies the next higher level of abstraction that allows storage equipment to be pooled together being a single rational system that can be were able independently from other gadgets in a network or by a data middle. This is almost like how compute 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 intended for easier management.
