What is Virtual Data Storage?
Virtual info storage identifies the software that abstracts the physical locations of data on several hardware arrays into a rational view meant for application gain access to. The goal is to get rid of the dependency between where the data is accessed and where it is physically stored, streamline day to day functions such as moving storage to a new location or increasing the capacity of existing hard disk drives without disrupting access. There are many types of virtual storage space software solutions starting from simple document systems to advanced mixture level virtualization that offer the same benefits as number based volume management.
Contrary to basic sole hard disk drives, the majority of disk arrays already offer some form of virtualization by using REZZOU schemes to mix multiple physical disks as one logical machine that can be partitioned later. Heightened arrays commonly include cloning and remote replication services. However these kinds of array centered solutions will be limited in what they can perform as they rely upon the storage space controller to carry out the virtualization.
Storage area virtualization offers the next higher level of abstraction that enables storage hardware to be pooled together as a single rational virtual data storage gadget that can be were able independently from other units in a network or by a data centre. This is a lot like how calculate virtualization (VMWare ESX or Hyper-V) abstracts the physical compute components into a rational view. In some instances, storage virtualization can even combine unlike components from multiple networks and vendors into a single pool pertaining to easier administration.
