  • Detection and configuration of SAS/SATA connection
    Patent number: 7996575
    Abstract: Given the different configurations for SAS and SATA Host and Target Ports, embodiments of the present invention automatically detect the configuration of SATA and SAS Phys when any device is inserted into a port enclosure and properly configure the connection regardless of the Phy configuration of the connected device. When a device is connected to the system, the port listens for either a SATA or SAS OOB signal to determine if the receive pin of the port is properly connected to the transmit signal of the attached device. By switching the configuration periodically and listening for the OOB signal, the port can determine which configuration is proper. Once a signal is detected, the port can properly configure the connection and continue with the SATA or SAS insertion algorithm. A user may alternatively choose which configuration to use and bypass the automatic detection and configuration.

  • FLAGGING OF PORT CONDITIONS IN HIGH SPEED NETWORKS
    Publication number: 20090190476
    Abstract: A non-intrusive condition flag is introduced into high-speed data network for flagging a fault condition without interrupting the normal operation of the network. The condition flag is chosen to be one that is relatively not germane with respect to disrupting the behavior of the ports under a particular network protocol, or that is normally ignored by the network ports and/or devices. The non-intrusive condition flag can be in the form of a marker represented by designating new, currently undefined, Ordered Sets that would not cause the ports to disrupt network behavior. The marker is represented by repeating the same designated Ordered Set twice in sequence, to give the marker fault tolerance and prevent re-transmission. Ordered Sets may be chosen to identify a segment stall condition, a port busy condition, or a user defined condition in a FC network.
