Storage virtualization abstracts physical disks and devices into a central pool of storage. This enables organizations to cut back datacenter intricacy, costs and overcrowded storage space hardware. In addition, it provides for faster, more reliable access to essential applications.

HPE storage virtualization causes this possible by creating a great abstraction covering between the hardware of a physical disk or perhaps drive plus the operating system that accesses it. This software layer covers the details for the disk or drive to achieve the illusion of any single monolithic disk which can be used with existing application software. This allows with regards to Shorter, more consistent access to data and increased performance without the need of the get of more hardware.

There are lots of different forms of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) virtualization. The most frequent form is usually network structured which will utilizes an intelligent switch or purpose-built gadget to connect to any or all the storage space devices in an FC or perhaps iSCSI SAN and symbolizes them as a single virtual pool of storage with each host.

When ever implemented correctly, a storage manager can change the place of the reasonable disk which a host is normally using merely by remapping the mapping of where the meta-data resides over the underlying physical storage device. However , the granularity of the mapping can easily limit how quickly the reasonable disk could be remapped and just how much extra space will need to be readily available before the earlier logical storage can be designated as free. Also, most implementations need that change your mind of a storage area virtualization environment be done in a non-disruptive approach which needs that the mapping granularity is certainly small enough to allow for this.
