  In the context of computing, a controller is a hardware device that administers or directs the flow of data between two units. A storage controller is an equipment that supervises the storage arrays. The storage controller mainly has three elements: cache memory, connection interface with the network & storage devices, and Central Processing Unit (CPU). A storage controller is also known as array controller or storage processor. It assimilates the memory areas in several memory devices and offers them as a single memory area. Performing these tasks of reading and writing data from the memory and transferring it to the server is done by the storage controller. Processing tasks in an efficient and stable manner is the role of the storage controller. Additionally, storage controller performs different processing tasks such as acquisition of snap shots and dynamic allocation of volume capacity, in order to realize a range of added-value functions. Storage controllers are availab...
