Precisely what is Storage Virtualization?

Storage virtualization abstracts physical hard disks and hard disks into a central pool of storage. This permits organizations to cut back datacenter complexity, costs and overcrowded storage hardware. Additionally, it provides for faster, more reliable access to essential applications.

HPE storage virtualization makes this possible simply by creating a great abstraction level between the components of a physical disk or perhaps drive and the operating system that accesses it. This software layer conceals the details in the disk or perhaps drive to achieve the illusion of your single monolithic disk which you can use with existing application program. This allows for the purpose of Smaller, more consistent access to info and much better performance without the need of the purchase of more hardware.

There are lots of different kinds of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) virtualization. The most common form is normally network centered which utilizes a good switch or purpose-built equipment to connect to all or any the safe-keeping devices within an FC or perhaps iSCSI SAN and signifies them like a single online pool of storage with each host.

When implemented correctly, a storage forvalter can change the place of the logical disk a host is certainly using simply by remapping the mapping of exactly where the meta-data resides over the underlying physical storage device. However , the granularity with the mapping can easily limit how fast the reasonable disk could be remapped and just how much extra space will need to be readily available before the prior logical disk can be huge as absolutely free. Also, the majority of implementations require that change your mind of a storage area virtualization environment be done in a non-disruptive approach which requires that the umschlüsselung granularity can be small enough to allow for this kind of.
