What Is Storage Virtualization?

Storage virtualization abstracts myvirtualstorage.blog/best-types-of-acquisition-strategy-to-use-based-on-the-business-needs/ physical hard disks and turns into a centralized pool of storage. This enables organizations to lower datacenter difficulty, costs and overcrowded storage space hardware. In addition, it provides for quicker, more reliable access to critical applications.

HPE storage virtualization makes this possible by creating an abstraction level between the components of a physical disk or drive plus the operating system that accesses it. This application layer conceals the details with the disk or drive to have the illusion of the single monolithic disk you can use with existing application software. This allows to get Smaller, more continual access to data and increased performance without requiring the invest in of additional hardware.

There are several different varieties of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) virtualization. The most common form is network structured which utilizes an intelligent switch or perhaps purpose-built gadget to connect to all the storage devices in an FC or iSCSI SAN and symbolizes them like a single online pool of storage to each host.

When ever implemented correctly, a storage bestyrer can change the place of the reasonable disk a host can be using simply by remapping the mapping of exactly where the meta-data resides at the underlying physical storage device. However , the granularity from the mapping may limit how quickly the logical disk can be remapped and just how much extra space will need to be readily available before the previous logical disk can be proclaimed as absolutely free. Also, many implementations need that back out of a storage space virtualization environment be done within a non-disruptive fashion which needs that the mapping granularity is usually small enough to allow for this.
