Precisely what is Storage Virtualization?

Storage virtualization abstracts physical hard disk drives and forces into a centralized pool of storage. This permits organizations to lessen datacenter complexity, costs and overcrowded storage hardware. In addition, it provides for quicker, more reliable access to critical applications.

HPE storage virtualization makes this possible by creating a great abstraction part between the equipment of a physical disk or drive plus the operating system that accesses that. This computer software layer skins the details of this disk or drive to achieve the illusion of any single monolithic disk which you can use with existing application software program. This allows to get Smaller, more reliable access to info and better performance without the need of the get of additional hardware.

There are lots of different forms of storage virtualization, including network based (SAN) and block-based (FC/iSCSI/SATA) virtualization. The most frequent form is certainly network centered which will utilizes a smart switch or perhaps purpose-built machine to connect to everyone the storage space devices in an FC or iSCSI SAN and gives them as being a single digital pool of storage with each host.

Once implemented correctly, a storage manager can change the place of the rational disk that a host is usually using merely by remapping the mapping of exactly where the meta-data resides within the underlying physical storage device. However , the granularity belonging to the mapping can easily limit how fast the logical disk can be remapped and just how much extra space virtual data storage will need to be readily available before the past logical disk can be runs as totally free. Also, the majority of implementations require that back out of a storage space virtualization environment be done within a non-disruptive way which needs that the umschlüsselung granularity is definitely small enough to allow for this.
