Abstract: A computer-implemented system and method for performance profiling on a target device. The computer-implemented method includes configuring the target device to operate in a first mode or a second mode, and receiving a write command from a host device. When the target device is configured to operate in the first mode, the method includes sending an authorization to send write data to the host device, and receiving write data from the host device. When the target device is configured to operate in the second mode, the method includes allocating a reserved write buffer on the target device, and receiving write data from the host device using the write buffer.

Abstract: A redundant data storage system is provided comprising a first controller with top-level control of a first memory space and a second controller with top-level control of a second memory space different than the first memory space. The system is adapted for asynchronously reflectively writing state information by the first controller to the second memory space; alternatively the system is adapted for asynchronously reflectively writing state information by the second controller to the first memory space. A method is provided for operating the redundant data storage system by resolving any inconsistency between the existing state information and a modified state information associated with a state information change request, and for switching control in the redundant data storage system between the controllers.
