Abstract: A method for dynamic storage tiering may include, but is not limited to: receiving an input/output (I/O) request from a host device; determining whether the I/O request results in a cache hit; and relocating data associated with the I/O request between a higher-performance storage device and lower-performance storage device according to the determination whether the data associated with the I/O request is stored in a cache.

Abstract: A storage array is disclosed. The storage array may comprise a plurality of storage units configured for providing data storage; a processing module configured for hosting a virtual machine; and an application integration framework provided by the virtual machine. The application integration framework may comprise an application interface configured for interfacing with at least one application running on an application server, where the application server is communicatively connected with the storage array. The application integration framework may further comprise a software development kit (SDK) communicatively coupled to the application interface via a communication module, the SDK being configured for providing a programmatic interface to the at least one application and enabling the at least one application for delegating at least a portion of data processing operations to the storage array.
