摘要： A mechanism uses in-situ bidirectional cable wrapping for determining different cable lengths. A calibration mechanism calibrates the high speed transmitter/receiver pair characteristics, and, thus, optimizes the transmission performance between subsystems. The calibration mechanism mitigates the need for frequent error correction and does not incur the performance degradation associated with error correction techniques.

摘要： A mechanism detects cable length in a storage subsystem with wide ports. The mechanism uses in-situ bidirectional cable wrapping for determining different cable lengths. The mechanism under-margins transmitter output to failure for each external port and even for each PHY within a wide port. Based on the transition point from “good” wrap to “bad” wrap, the cable length may be determined. The transition point identifies if the cable is long or short, at which point the optimum tuning parameters can accordingly be set. A calibration mechanism calibrates the high speed transmitter/receiver pair characteristics, and, thus, optimizes the transmission performance between subsystems. The calibration mechanism mitigates the need for frequent error correction and does not incur the performance degradation associated with error correction techniques.

摘要： A mechanism is provided for discovering and isolating failure of high speed traces in a manufacturing environment. The mechanism utilizes transmit pre-emphasis and receiver equalization in combination with attenuated wrap plugs to enhance discovery and isolation of manufacturing defects in the manufacturing environment. The mechanism adjusts pre-emphasis and equalization in real time in high speed devices, allowing for much greater variation to compensate for design margins and specification variances. While the card is under test with wrap-backs installed, the pre-emphasis and receiver equalization are brought to the limits while logging the bit error rate to a non-volatile memory element. The mechanism then compares the bit error rate information to empirically derived signatures for failure isolation.

摘要： A single fibre channel switch or serial attached SCSI expander applies zoning on the initiator ports to each of the two ports of one or more drives. The fibre channel switch or serial attached SCSI expander uses zoning to connect both ports of each drive to a single expander and set the zones in the expander such that each zone includes at least one initiator port and one drive port.

摘要： An apparatus, method, and discriminator circuit are provided for filtering false signals. A discriminator circuit receives a low-state signal via an input and, responsive to receiving the low-state signal, the discriminator circuit compares the low-state signal to a static signal. Responsive to the low-state signal being greater than the static signal, the discriminator circuit outputs a high-voltage signal. The high-voltage signal output by the discriminator circuit indicates that the low-state signal is a false low signal. Responsive to the low-state signal being less than or equal to the static signal, the discriminator circuit outputs a low-voltage signal. The low-voltage signal output by the discriminator circuit indicates that the low-state signal is a valid low signal.

摘要： A mechanism is provided for dynamically zoning or rezoning serially attached SCSI expanders using an intelligent failover mechanism. The mechanism uses serially attached SCSI (SAS) zoning by zoning off one port of the SAS hard disk drive to the initiator that does not “own” the resource. The drive will appear to only one initiator as a result of the zoning. In the event of a failure on the “owning” initiator, the failover mechanism may change the zones, zoning off the failed initiator and including the drives in the zone(s) of the active initiator(s). By using zoning in this fashion, the zoning mechanism creates an active-passive SAS multiplexer with configurable and intelligent failover.
摘要翻译：提供了一种机制，用于使用智能故障转移机制动态分区或重新分区串行连接的SCSI扩展器。该机制通过将SAS硬盘驱动器的一个端口分区到不“拥有”资源的启动器，使用串行连接的SCSI（SAS）分区。由于分区，驱动器将只显示一个启动器。在“拥有”启动器发生故障的情况下，故障切换机制可能会更改区域，将发生故障的启动器分区，并将活动启动器的区域中的驱动器包括在内。通过以这种方式使用分区，分区机制创建了一个主动 - 被动的SAS多路复用器，具有可配置和智能的故障切换功能。
