Abstract:
1. A method of handling multiple data storage requests performed by a storage subsystem, the method comprising: receiving a first set of data storage commands for accessing a storage of the storage subsystem according to a first signal interface; receiving a second set of data storage commands for accessing the storage of the storage subsystem according to a second signal interface; accessing a priority parameter stored in the storage subsystem; and processing the first set of data storage commands and the second set of data storage commands in accordance with the priority parameter, wherein the first and second sets of data storage commands are received from two different host systems that are concurrently connected to the storage subsystem, the storage comprising a nonvolatile memory, and wherein the priority parameter is configured to designate an order for processing the first set of data storage commands and the second set of data storage commands based on at least one of a first host providing the first set of data storage commands according to the first signal interface and a second host providing the second set of data storage commands according to the second signal interface, a first type of command associated with the first set of data storage commands and a second type of command associated with the second set of data storage commands, and a first set of data included in the first set of data storage commands and a second set of data included in the second set of data storage commands.
