Abstract
Disclosed is a system using a SAS host controller and SAS expanders to control multiple SATA end devices where the memory contained on the SAS host controller is fixed to ease the cost and power consumption of the SAS host controller device, but where there is an expanded ability to support additional SATA end devices by configuring the allowed native command queue depth to be smaller for each SATA end device, thus allowing more SATA end devices to be supported by a single SAS host controller. An embodiment of the invention has three possible preset configuration states: thirty-two SATA end devices with a native command queue depth of thirty-two; sixty-four SATA end devices with a native command queue depth of sixteen; and one-hundred-twenty-eight SATA end devices with a native command queue depth of eight.
