Storage virtualization abstracts physical disks and generates into a centralized pool of storage. This permits organizations to cut back datacenter complexity, costs and overcrowded storage space hardware. Additionally, it provides for quicker, more reliable access to important applications.
HPE storage virtualization makes this possible simply by creating a great abstraction layer between the hardware of a physical disk or perhaps drive and the operating system that accesses that. This program layer covers the details of your disk or drive to have the illusion of an single monolithic disk which can be used with existing application software program. This allows with respect to Faster, more reliable access to data and superior performance lacking the get of more hardware.
There are numerous different varieties of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) virtualization. The most common form is definitely network depending which utilizes an intelligent switch or purpose-built gadget to connect to all the safe-keeping devices within an FC or iSCSI SAN and presents them as a single online pool of storage to each host.
When ever implemented correctly, a storage owner can change the location of the rational disk which a host is usually using by just remapping the mapping of where the meta-data resides relating to the underlying physical storage device. However , the granularity for the mapping may limit how fast the logical disk may be remapped and how much extra space will need mundo inflable de interior to be readily available before the earlier logical hard disk drive can be as well as as absolutely free. Also, many implementations need that back of a storage space virtualization environment be done in a non-disruptive approach which requires that the umschlüsselung granularity is definitely small enough to allow for this.
