Precisely what is Virtual Data Storage?


Virtual data storage identifies the software that abstracts the physical locations of info on unique hardware arrays into a reasonable view for the purpose of application access. The target is to eliminate the dependency among where the info is contacted and exactly where it is actually stored, simplifying day to day procedures such as shifting storage into a new site or advancing the capacity of existing disks without disrupting access. There are several types of virtual storage software solutions ranging from simple file systems to advanced mixture level virtualization that offer the same benefits as hosting server based volume 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 product that can be partitioned later. More advanced arrays typically include cloning and distant replication products. However these array established solutions happen to be limited in what they can do as they depend on the safe-keeping controller to perform the virtualization.

Storage space virtualization offers the next amount of abstraction that allows storage components to be pooled together as a single logical unit that can be maintained independently from other devices in a network or for a data middle. This is almost like how calculate virtualization (VMWare ESX or perhaps Hyper-V) abstracts the physical compute equipment into a rational view. In some instances, storage virtualization can even integrate unlike components from multiple networks and vendors into a single pool pertaining to easier administration.
