Abstract Data Type Definition

Virtualization encounters "bottlenecks" in traditional data centers, in the process of the IT system construction, the application and storage of 1:1, 2:1, 4:1, 8:1, 12:2 and so on are the corresponding physical configuration, the static load mode can be provided to the application side of the performance, capacity is completely predictable, storage quality is guaranteed. 　　However, the lack of flexibility in this deployment, the basic use of dry manual operations, often take weeks of deployment time, easy to manage islands, and with the passage of time, storage performance is getting worse, affecting TCO. With the cloud ...
