Storage virtualization abstracts physical hard disk drives and drives into a centralized pool of storage. This permits organizations to cut back datacenter intricacy, costs and overcrowded storage hardware. It also provides for quicker, more reliable access to significant applications.

HPE storage virtualization causes this possible by creating a great abstraction covering between the equipment of a physical disk or perhaps drive plus the operating system that accesses it. This software layer skins the details within the disk or drive to give the illusion of a single monolithic disk that can be used with existing application computer software. This allows with regards to Shorter, more regular access to info and increased performance without requiring the pay for of more hardware.

There are various different sorts of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) virtualization. The most typical form is definitely network primarily based which in turn utilizes a good switch or perhaps purpose-built unit to connect to any or all the storage space devices in an FC or iSCSI SAN and gives them being a single online pool of storage with each host.

When ever implemented correctly, a storage officer can change the positioning of the reasonable disk that the host is normally using just by remapping the mapping of exactly where the meta-data resides over the underlying physical storage device. However , the granularity in the mapping may limit how fast the rational disk could be remapped and just how much extra space will need to be offered before the prior logical disc can be ski slopes as cost-free. Also, the majority of implementations require that change your mind of a storage area virtualization environment be done within a non-disruptive manner which requires that the umschlüsselung granularity is certainly small enough to allow for this.
