Abstract: A storage control system to provide file-level storage and block-level storage services. The storage control system has a computer system including a second 1/0 unit configured to receive block-level storage related requests, a processor unit, a first memory unit, and a storage unit; and a programmable logic device including a first 1/0 unit configured to receive file-level storage related requests, an interface unit configured to communicate with the computer system, one or more programmable hardware-implemented processing units and for processing of file-level storage related requests, and a second memory unit. The software components executed on the processor unit include a block-level storage management component and a virtualization management component; and a virtual machine managed by the virtualization management component executes a file-level management component to communicate with the programmable hardware-implemented processing units of the programmable logic device and to manage file-level storage services related to file-level storage related requests.
