摘要： Apparatus and associated methods for a simplified Serial SCSI Protocol (“SSP”) link layer within a SAS device. Features and aspects hereof provide a simplified SSP link layer processor to enable cost reduction and simplification of Serial Attached SCSI (“SAS”) devices requiring only limited SSP exchange functionality. In one embodiment, a SAS expander may incorporate the simplified SSP link layer features and aspects hereof to permit simple management of SAS devices coupled to the expander or coupled downstream through other expanders. The simplified SSP link layer suffices for simple SAS management functions while reducing cost and complexity of the SAS expander. Features and aspects hereof may be implemented with minimal customized circuits for SSP link layer management in the SAS device. In one aspect hereof, the simplified link layer processing may be implemented as a simplified state machine model in combinatorial logic coupled with any requisite memory components.

摘要： The present invention is directed to a method and apparatus of automatic power management control for a Serial ATA device directly attached to a SAS/SATA host controller. In an exemplary aspect of the present invention, it is determined whether a Serial ATA device is directly attached to a SAS/SATA host controller without using a SAS expander. When it is determined that the Serial ATA device is directly attached to the SAS/SATA host controller, an idle or active condition of a Serial ATA interface including the Serial ATA device and the SAS/SATA host controller is automatically detected. When the Serial ATA interface is in an idle condition, idle time of the Serial ATA interface is measured using a power down counter whose frequency is determined by a programmable register based on an input clock. When a power down counter value is equal to a first value, a request for a Partial power state is asserted, and Serial ATA interface is put into a Partial power state. When a power down counter value is equal to a second value, a request for a Slumber power state is asserted, and Serial ATA interface is put into a Slumber power state.

摘要： The present invention is directed to a method and apparatus of automatic power management control for a Serial ATA interface that utilizes a combination of IOP control and specialized hardware control. The method may include steps as follows. It is determined, preferably based on a value of the Automate bit in a Task File Ram of a Serial ATA interface, whether a Serial ATA device of the Serial ATA interface is being controlled via the IOP or controlled by the specialized Serial ATA automation hardware. When the Serial ATA device is controlled via the IOP, the IOP may decide when to power up/down the Serial ATA interface. When the Serial ATA device is controlled by the specialized Serial ATA automation hardware, the method may proceed as follows. An idle or active condition of a Serial ATA interface utilizing a combination of IOP control and specialized hardware control is then automatically detected. When Serial ATA is in an idle condition, idle time of Serial ATA interface is measured using a power down counter whose frequency is determined by a programmable register based on an input clock. When a power down counter value is equal to a first value, a request for a Partial power state is asserted, and Serial ATA interface is put into a Partial power state. When a power down counter value is equal to a second value, a request for a Slumber power state is asserted, and Serial ATA interface is put into a Slumber power state.

摘要： Methods and structures for efficiently storing task file information for a significant number of SATA devices coupled to a SATA storage controller. A RAM memory within the SATA storage controller may store task file information for virtually any number of SATA devices coupled to a SAS communication domain. An arbiter and multiplexing logic is coupled to multiple client logic blocks or processes of the controller each operable to control one or more corresponding SATA devices. The arbiter and associated multiplexing logic grants each client process an opportunity to control its corresponding devices by retrieving saved state information from the task file RAM storage.

摘要： 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.

摘要： Methods and associated structure to assure correct order in delivery of SATA frames over a SAS wide port. In one aspect hereof, new connection requests from a SATA device are rejected until prior frames residing in receive buffers of the SAS/SATA controller are properly processed. In another aspect, when a device is already connected to the controller, the SAS/SATA controller may prevent return of a receiver ready primitive in response to a transmitter ready primitive until previously received frames are removed from the receive buffers.
