Storage virtualization abstracts physical hard disks and forces into a centralized pool of storage. This permits organizations to cut back datacenter difficulty, costs and overcrowded storage hardware. Additionally, it provides for quicker, more reliable access to critical applications.
HPE storage virtualization causes this possible by simply creating a great abstraction layer between the equipment of a physical disk or drive as well as the operating system that accesses this. This computer software layer covers the details within the disk or drive to have the illusion of an single monolithic disk which can be used with existing application computer software. This allows to get Smaller, more frequent access to info and improved performance without the need of the buy acquisition strategy to use based on the business needs of more hardware.
There are lots of different sorts of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) virtualization. The most typical form is network based mostly which in turn utilizes a smart switch or perhaps purpose-built product to connect to all the storage devices within an FC or iSCSI SAN and reveals them as a single electronic pool of storage to each host.
When implemented correctly, a storage kurator can change the place of the logical disk which a host is certainly using by just remapping the mapping of where the meta-data resides in the underlying physical storage device. However , the granularity from the mapping can limit how quickly the rational disk could be remapped and how much extra space will need to be obtainable before the past logical disk can be runs as absolutely free. Also, many implementations need that back of a storage virtualization environment be done in a non-disruptive approach which needs that the mapping granularity is normally small enough to allow for this.
