What Is Storage Virtualization?

Storage virtualization abstracts physical hard disks and devices into a centralized pool of storage. This permits organizations to minimize datacenter intricacy, costs and overcrowded storage space hardware. It also provides for more quickly, more reliable access to crucial applications.

HPE storage virtualization causes this possible by simply creating a great abstraction part between the components of a physical disk or perhaps drive plus the operating system that accesses this. This software layer conceals the details for the disk or drive to give the illusion of your single monolithic disk you can use with existing application application. This allows for Quicker, more dependable access to data and increased performance without requiring the buy of more hardware.

There are numerous different sorts of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) virtualization. The most common form is usually network primarily based click this site which will utilizes a brilliant switch or purpose-built system to connect to all the safe-keeping devices in an FC or perhaps iSCSI SAN and positions them as being a single electronic pool of storage to each host.

When ever implemented correctly, a storage kurator can change the location of the logical disk which a host is certainly using just by remapping the mapping of where the meta-data resides relating to the underlying physical storage device. However , the granularity of this mapping may limit how quickly the rational disk could be remapped and exactly how much extra space will need to be readily available before the past logical hard drive can be runs as cost-free. Also, many implementations need that back of a storage virtualization environment be done within a non-disruptive way which requires that the mapping granularity is usually small enough to allow for this.
