其实存储虚拟化早就不是什么新鲜的概念,它的发展,应该说是随着计算机技术的发展而发展起来的,最早是始于70年代。由于当时的存储容量,特别是内存容量成本非常高、容量也很小,对于大型应用程序或多程序应用就受到了很大的限制。为了克服这样的限制,人们就采用了虚拟存储的技术,最典型的应用就是虚拟内存技术。随着计算机技术以及相关信息处理技术的不断发展,人们对 In fact, storage virtualization has long been nothing new concept, its development, it should be said that with the development of computer technology developed, the earliest began in the 70s. Due to the storage capacity at the time, especially the memory cost is very high, the capacity is small, for large applications or multi-program applications have been greatly limited. In order to overcome such restrictions, people have adopted the technology of virtual storage, the most typical application is the virtual memory technology. With the continuous development of computer technology and related information processing technology, people are right
