摘要： A method and apparatus are provided for controlling the powering-up or spin-up of devices such as hard drives using expanders in a SAS topology. The method and apparatus provides a mechanism to coordinate spin-up control among a topology of expanders. The present invention enables an expander to both process the reception of the NOTIFY command to spin up attached devices and to propagate such command to further expanders. Hierarchical spin-up control provides an advantageous, in-band mechanism that controls the expanders within the topology to limit the total number of devices powering-up at any given time.

摘要： A system and method for providing redundant access paths to a storage device make use of a processor to analyze instructions received from hosts to allow for command queuing, host switching, and command replacement where necessary. The system allows for either Serially Attached SCSI or Serial ATA hard drives to be connected to the same topology and to require no host intervention on the coordination of drive access in a multi-host environment. A single ported SATA device can then appear multi-ported and can support a redundant architecture within a SAS topology.

摘要： A method and system are provided for broadcast message filtering in SAS expanders. Common SAS topology defined by ANSI T10 specification only supports spanning tree topology (without loops) interconnection among multiple end devices and expander devices. Broadcast message filtering provides a mechanism to selectively discard broadcast messages, or primitives, in the SAS expanders to break the infinite loop path that broadcast primitives can traverse. This enables new SAS physical topologies with loops that are otherwise difficult or impossible to realize using SAS expanders that handle primitive broadcasts according to the definition of the SAS standard. By allowing redundant paths in a SAS topology, the problem of infinite broadcast flooding in SAS topology is reduced. Selectively forwarding broadcast messages can be based on whether the broadcast was originated at the source phy, or received by the source phy, or based on whether the source phy is a filtered phy.
摘要翻译：提供了一种方法和系统，用于SAS扩展器中的广播消息过滤。 ANSI T10规范定义的常规SAS拓扑仅支持多个终端设备和扩展器设备之间的生成树拓扑（无环路）互连。广播消息过滤提供了选择性地丢弃SAS扩展器中的广播消息或原语以破坏广播原语可以遍历的无限循环路径的机制。这使得新的SAS物理拓扑具有循环，否则难以或不可能根据SAS标准的定义处理原始广播的SAS扩展器来实现。通过在SAS拓扑中允许冗余路径，减少了SAS拓扑中无限广播洪泛的问题。选择性地转发广播消息可以基于广播是源自源phy还是由源phy接收，或者基于源phy是否是过滤的phy。

摘要： A bus holder for coupling to an integrated circuit bus driven by a plurality of tri-state devices. The bus holder has a bidirectional port and first and second test ports. Logic circuitry coupled between the respective ports is configured such that application of a logic 0 to the first test port causes the bidirectional port to drive whatever logic value is applied to that port; application of a logic 1 to the first test port and application of a logic 0 to the second test port pulls the bidirectional port down to a logic 0; and, application of a logic 1 to both the first and second test ports pulls the bidirectional port up to a logic 1.

摘要： Broadcast primitive filtering in a SAS expander using virtual domains. The virtual domains can be non-overlapping or overlapping logical subsets of the physical topology, or a logical construct based on the membership of a device within a group. Broadcast event propagation is handled in accordance with predetermined policies associated with the virtual domains. These policies can, for example, include limiting the broadcast traffic within the boundaries of the logical zones defined by the subsets, or routing the broadcast events in accordance with access policies, or privileges, associated with the group.

摘要： A Forward Propagation Architecture is a novel switch architecture based on well-known unicast switching architectures, and provides two desirable properties: (1) no rearrangement of established calls is ever required and (2) the architecture is strictly non-blocking for multicast, even when multicast destinations are dynamically added to existing calls. These properties (excluding dynamic multicast destination addition) can be provided by standard architectures or Time:Space:Time architectures with speedup proportional to the width of the widest multicast to be supported. The speedup required by the FPA is constant and practical (approximately 4× speedup) and at significantly less hardware cost than n2 architectures. The key to the FPA's capability is a sequentially doubled fabric with a feedback loop. The FPA requires a routing algorithm for connection setting. The connection-setting algorithm is sufficiently simple to be implemented in hardware.

摘要： A method and apparatus for determining a set of common link rates for communication between two storage network elements in a storage network system. During the speed negotiation process, a controlling storage network element receives supported link rate information from a connected storage network element without providing any information in return. By not providing such information, although the speed negotiation process may not be completed, the controlling storage network element is still able to determine the supported link rates of the connected storage network element.

摘要： A plurality of time-division multiplexed data streams which are merged into a single data stream containing a plurality of data words and which are characterized by state vectors, are concurrently processed. The state vectors are stored in a read-write memory having a plurality of addressable memory locations. During an initial clock cycle, a pipeline receives an input data word from one of the data streams, an input state vector characterizing that data stream, and the memory location address of the input state vector. During one or more intermediate clock cycles, the pipeline processes the input data word and the input state vector to yield an output data word and an output state vector. During a final clock cycle, the pipeline transfers the output data word to an outgoing data stream, and transfers the output state vector into the aforementioned memory location address. A controller coupled to the memory and to the pipeline synchronizes operation thereof. A null cycle generator coupled to the pipeline and to the controller inserts null cycles into the concurrently processed data streams at regular time intervals and outputs a NULL signal to the controller during each null cycle. A multiplexer coupled between the controller and the memory multiplexes access to the memory between the controller/pipeline, and an alternate controller. Read access to the memory by the controller or pipeline is inhibited while the NULL signal is output, and write access to the memory by the pipeline is inhibited while an OUTGOING NULL replica of the NULL signal is being output by the pipeline during the final clock cycle. Accordingly, the alternate controller may gain read access to the memory while the NULL signal is output, and may gain write access to the memory while the OUTGOING NULL signal is output.

摘要： A multi-port switch and a method of command switching using such a switch. Multiple virtual targets provide multiple hosts with access to the physical target device attached to the target interface of the switch. The switch intelligently dispatches operations received by the virtual targets to the physical storage target device to provide shared access. In doing so, the communication between the switch and the physical target can fully comply with the SATA protocol without the physical target being aware that the operations have originated from multiple physical hosts, and without the multiple physical hosts being aware of the shared nature of the physical SATA target device.
