What Is Storage Virtualization?
Storage virtualization abstracts physical hard disk drives and devices into a central pool of storage. This permits organizations to cut back datacenter intricacy, costs and overcrowded storage area hardware. In addition, it provides for faster, more reliable access to crucial applications.
HPE storage virtualization causes this possible by creating an abstraction level between the equipment of a physical disk or drive and the operating system that accesses this. This software layer skins the details in the disk or drive to have the illusion of the single monolithic disk that can be used with existing application application. This allows intended for Smaller, more consistent access to info and superior performance without the need of the pay for of more hardware.
There are lots of different types of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) https://myvirtualstorage.blog/how-much-does-it-cost-to-use-a-data-room virtualization. The most common form can be network based upon which usually utilizes a good switch or purpose-built equipment to connect to everyone the storage devices within an FC or iSCSI SAN and reveals them to be a single digital pool of storage to each host.
Once implemented correctly, a storage officer can change the location of the logical disk that the host can be using by simply remapping the mapping of exactly where the meta-data resides over the underlying physical storage device. However , the granularity for the mapping can easily limit how quickly the rational disk can be remapped and just how much extra space will need to be readily available before the past logical hard disk drive can be as well as as cost-free. Also, many implementations need that change your mind of a storage virtualization environment be done in a non-disruptive fashion which needs that the mapping granularity is small enough to allow for this kind of.
