Abstract: Methods and systems for encoding and/or decoding digital signals representing serial attached SCSI (SAS) out of band (OOB) signals exchanged over an optical communication between two SAS devices. A SAS OOB signal to be transmitted from a first SAS device to a second SAS device is first encoded as a digitally encoded signal representing the analog SAS OOB signal and then transmitted over an optical communication medium to another SAS device. A receiving SAS device coupled to an optical communication medium decodes a received digitally encoded signal to detect a received, encoded SAS OOB signal and processes the received SAS OOB signal when receipt is detected. The digitally encoded signal may comprise an idle word portion and a burst word portion to represent various SAS OOB signals. Further, the digitally encoded signal may be precomputed in a variety of disparity forms and stored in a memory for lookup and retrieval.

Abstract: Apparatus and methods for full address resolution in a zoning SAS expander. A single memory circuit is used in a zoning SAS expander to store zone information associated with the SAS address (e.g., WWN) of devices exchanging information through the expander. The source and destination addresses in a received SAS frame are used as inputs to the memory circuit to generate outputs of the memory circuit representing the source and destination zone group identifiers. These outputs are then applied to the zone permission table to determine the zoning permission for forwarding the frame through the expander. Pipelined logic within the expander sequences the operations of the memory circuit and the zone permissions table to account for clock cycle delays in processing of each. In one exemplary embodiment, the memory circuit is a content addressable memory (CAM). In another exemplary embodiment, the CAM also includes port routing information.

Abstract: A precision delay circuit having two delay chains to provide equal delay periods is described. A rising edge of an input pulse signal is supplied to the first delay chain and the falling edge is supplied to the second delay chain. The resultant output signal maintains the pulse width of the input signal and pulse distortion is minimized. In another aspect, a delay circuit for generating a delayed assertion signal that does not maintain the width of the original input signal pulse and which is substantially immune to noise problems is described. An assertion edge of a resultant pulse is timed by the incoming pulse, but the de-assertion edge is timed by the delayed de-assertion edge of the incoming pulse.

Abstract: A method for communicating on a SCSI bus permits out-of-band addressing and communication for normally non-addressable devices such as SCSI expanders and terminators. The method remaps 18 SCSI data lines for out-of-band operation and manipulates no more than those data lines. Some of the data lines are remapped for purposes of out-of-band signaling and data transfers. Advantageously, manipulation of only the SCSI data lines prevents the possible response of a device on the SCSI network that does not support the out-of-band operations. Accordingly, the disclosed method is backward compatible with existing SCSI networks while allowing implementation of devices having the increased functionality of out-of-band communication.

Abstract translation: 用于在SCSI总线上通信的方法允许通常不可寻址的设备（例如SCSI扩展器和终结器）进行带外寻址和通信。 该方法重新映射18个SCSI数据线进行带外操作，并且不会超过那些数据线。 一些数据线被重新映射以用于带外信令和数据传输。 有利的是，仅操纵SCSI数据线阻止了SCSI网络上不支持带外操作的设备的可能响应。 因此，所公开的方法向后兼容现有的SCSI网络，同时允许实现具有增加的带外通信功能的设备。
