    • The present disclosure includes methods and systems that share memory located on one PCIe based HBA across other PCIe based HBAs in the system. In addition, the backup battery is effectively shared across multiple PCIe based HBAs in the system. This approach saves significant costs by avoiding the need to have a separate DRAM with its own dedicated battery backup on each HBA board in the system. This also allows the redundant memory and backup batteries to be removed while still retaining the same functionality through the common DDR3 memory chip and battery backup shared across multiple HBAs in the system. The component cost for batteries and memory, management module, board space, and the board manufacturing cost are all reduced as a result.
    • 本公开包括在系统中共享基于一个基于PCIe的HBA跨另一个基于PCIe的HBA的存储器的存储器的方法和系统。 此外,备份电池在系统中跨多个基于PCIe的HBA有效共享。 这种方法通过避免需要在系统中的每个HBA板上具有单独的具有自己的专用电池备份的DRAM来节省大量成本。 这也允许冗余存储器和备用电池被移除,同时通过在系统中的多个HBA共享的通用DDR3存储器芯片和电池备份来保持相同的功能。 电池和存储器的组件成本,管理模块,电路板空间和电路板制造成本都有所下降。

    • Methods and structures within a SAS domain for automated tuning performance of a coupled pair of transceivers. In one aspect hereof, control registers of a transmitting transceiver coupled to a receiving transceiver are adjusted to a plurality of distinct combinations of settings. For each distinct setting, a test pattern may be transmitted from the transmitting transceiver to the receiving transceiver. Status registers of the transmitting transceiver and of the receiving transceiver may be read to identify errors in the transmission. Identified errors are counted for each for distinct setting of the control registers to determine a preferred setting to best tune operation of the transceiver pair. The testing may be performed by any SAS initiator device or SAS expander acting as an initiator and may be performed on any coupled pair of transceiver in the SAS domain.
    • SAS域内的方法和结构,用于自动调整耦合的一对收发器的性能。 在一个方面,耦合到接收收发器的发送收发器的控制寄存器被调整到多个不同的设置组合。 对于每个不同的设置,测试模式可以从发送收发器发送到接收收发器。 可以读取发送收发器和接收收发器的状态寄存器,以识别发送中的错误。 为每个控制寄存器的不同设置计算识别的错误,以确定最佳调谐收发器对的操作的优选设置。 可以由作为发起者的任何SAS启动器设备或SAS扩展器执行测试,并且可以在SAS域中的任何耦合的收发器对上执行该测试。
