Storage virtualization 储存虚拟化
In computer science, storage virtualization uses virtualization to enable better functionality and more advanced features in computer data storage systems.
Broadly speaking, a "storage system" is also known as a storage array or disk array or a filer. Storage systems typically use special hardware and software along with disk drives in order to provide very fast and reliable storage for computing and data processing. Storage systems are complex, and may be thought of as a special purpose computer designed to provide storage capacity along with advanced data protection features. Disk drives are only one element within a storage system, along with hardware and special purpose embedded software within the system.
