Zusammenfassung:An information handling system includes a processor and a system memory coupled to the processor. The system has a plurality of persistent mass storage devices including first and second storage devices. A device controller includes a first port operably connected to the first storage device and a second port operably connected to the second storage device. The controller transfers data between system memory and the storage devices. System firmware includes instructions to configure the controller to define a first command list and frame information structure (FIS) associated with the first port and a second command list and FIS associated with the second port where the first and second command lists share a common block of system memory.
