Abstract: Systems and methods for throttling a fabric login (FLOGI) in a Fibre Channel (FC) adapter are provided. One system includes a first tracking mechanism, a second tracking mechanism, a switch, and a FC adapter. The FC adapter comprises three or more FLOGIs and a controller configured to perform the below method. One method includes transmitting first and second FLOGI requests to the switch and indicating, via a first tracking mechanism, that a first FLOGI associated with the first FLOGI request and a second FLOGI associated with the second FLOGI request are active. The method further includes queuing a third FLOGI request until the first FLOGI request or the second FLOGI request is processed by the switch and indicating, via a second tracking mechanism, that a third FLOGI associated with the third FLOGI request is queued. Also provided are computer storage mediums including computer code for performing the above method.

Abstract: A method for initializing a fibre channel link upon a failure of a standard speed negotiation algorithm is provided. The standard speed negotiation algorithm is disabled. A link speed is set to a highest possible link speed not yet attempted outside the standard speed negotiation algorithm, initializing the fibre channel link if the link speed is negotiated at a maximum link speed. If the link speed is negotiated at a speed less than the maximum link speed, the standard speed negotiation algorithm is reattempted, initializing the fibre channel link according to the standard speed negotiation algorithm if the reattempt is successful.

Abstract translation: 提供了一种在标准速度协商算法失败时初始化光纤通道链路的方法。 标准速度协商算法被禁用。 链路速度被设置为在标准速度协商算法之外尚未尝试的尽可能高的链路速度，如果以最大链路速度协商链路速度，则初始化光纤信道链路。 如果以低于最大链路速度的速度协商链路速度，则重新尝试标准速度协商算法，如果重试成功，则根据标准速度协商算法初始化光纤信道链路。

Abstract: Systems and methods for scanning ports for work are provided. One system includes one or more processors, multiple ports, a first tracking mechanism, and a second tracking mechanism for tracking high priority work and low priority work, respectively. The processor(s) is/are configured to perform the below method. One method includes scanning the ports, finding high priority work on a port, and accepting or declining the high priority work. The method further includes changing a designation of the processor to TRUE in the first tracking mechanism if the processor accepts the high priority work such that the processor is allowed to perform the high priority work on the port. Also provided are computer storage mediums including computer code for performing the above method.

Abstract translation: 提供扫描工作端口的系统和方法。 一个系统包括分别用于跟踪高优先级工作和低优先级工作的一个或多个处理器，多个端口，第一跟踪机构和第二跟踪机构。 处理器被配置为执行以下方法。 一种方法包括扫描端口，在端口上找到高优先级的工作，以及接受或拒绝高优先级的工作。 该方法还包括如果处理器接受高优先级的工作，使处理器能够在端口上执行高优先级的工作，则在第一跟踪机构中将处理器的指定改变为TRUE。 还提供了包括用于执行上述方法的计算机代码的计算机存储介质。

Abstract: A method for logging a repetitive error in a computer system is provided. The repetitive error is logged after each of a series of progressively increasing time periods. The logging commences when the repetitive error is first identified and concludes when the repetitive error is no longer identified.

Abstract translation: 提供了一种在计算机系统中记录重复错误的方法。 在一系列逐渐增加的时间段中的每一个之后记录重复性错误。 当重复性错误首次被识别时，记录开始，并且当重复错误不再被识别时得出结论。

Abstract: A log-in resource release system includes a set of lists for managing log-in requests to a processing cluster input/output port from host server input/output ports. Host servers that have been granted memory structures within a memory storage device (“configured hosts”) are granted priority access to a storage processing device's input/output port (“cluster port”). If the cluster port has exhausted its log-in resources, log-on requests from non-configured hosts will be not be accepted. New log-in requests from configured hosts will cause a host connected at a link or transport layer but not an upper layer to be logged off. If no hosts are connected only at the link or transport layer, a non-configured host connected at an upper layer will be logged off. If only configured hosts are connected and only at the upper layer, the log-on request by the configured host will be denied.

Abstract translation: 登录资源释放系统包括一组用于管理从主机服务器输入/输出端口到处理集群输入/输出端口的登录请求的列表。 被授予内存存储设备（“配置的主机”）内存结构的主机服务器被授予对存储处理设备的输入/输出端口（“群集端口”）的优先权访问权限。 如果群集端口已耗尽其登录资源，则不会接受未配置主机的登录请求。 配置主机的新登录请求将导致连接在链路或传输层但不是上层的主机被注销。 如果没有主机仅在链路或传输层连接，则在上层连接的未配置的主机将被注销。 如果仅配置的主机已连接，并且仅在上层，则配置的主机的登录请求将被拒绝。
