Storage virtualization abstracts physical hard disk drives and turns into a central pool of storage. This permits organizations to relieve datacenter complexity, costs and overcrowded storage area hardware. It also provides for more quickly, more reliable access to significant applications.

HPE storage virtualization causes this possible by simply creating a great abstraction layer between the equipment of a physical disk or perhaps drive and the operating system that accesses it. This application layer skins the details of the disk or drive to achieve the illusion of an single monolithic disk which can be used with existing application software. This allows with respect to Faster, more constant access to data and improved performance without the need of the buy of additional hardware.

There are numerous different kinds of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) virtualization. The most common form is certainly network founded which will utilizes a good switch or purpose-built system to connect to everyone the safe-keeping devices within an FC or iSCSI SAN and shows them as being a single virtual pool of storage to each host.

The moment implemented correctly, a storage supervisor can change the positioning of the rational disk a host is using merely by remapping the mapping of where the meta-data resides in the underlying physical storage device. http://myvirtualstorage.blog However , the granularity of the mapping can limit how fast the logical disk may be remapped and exactly how much extra space will need to be obtainable before the earlier logical storage can be notable as free. Also, the majority of implementations require that back out of a safe-keeping virtualization environment be done within a non-disruptive method which needs that the mapping granularity is small enough to allow for this kind of.
