保存虚拟化（Storage virtualization）为计算机科学领域的一个观念与术语，是利用虚拟化技术，让有限的保存设备可以发挥更多的使用效益。 所谓储存虚拟化，是和云时代下分布式环境密不可分的。旨在在一个庞大的分布式服务器集群中，对分布在不同服务器主机上的海量数据有效地进行各种处理。

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.
