Storage virtualization is a fusion of several network storage tools in order for making the whole combination into a single storage unit. Storage virtualization is generally put into operation with the use of software applications and it is often found in SAN (storage area network), a super-fast sub-network of shared storage tools, and makes tasks including archiving, backup, and retrieval simpler and quicker.
For those who don’t know, storage virtualization occurs in two types: block virtualization and file virtualization. The former separates logical storage from physical storage so as to allow an end-user access data without hassle. On the other hand, the latter gives the end-user the leverage to maximize storage usage and server consolidation and to carry out seamless file migrations.
