摘要： A data-processing method and system generally comprises identifying a plurality of hardware resources associated with a data-processing apparatus, time-slicing the plurality of hardware resources. Thereafter the plurality of active hardware resources can be allocated among a plurality of active hardware resources associated with the data-processing apparatus, thereby allowing a limited number of hardware resources to service a larger number of physical devices associated with the data-processing apparatus. An appropriate hardware resource can be selected from among the plurality of active hardware resources utilizing one or more swapping algorithms.
摘要翻译：数据处理方法和系统通常包括识别与数据处理装置相关联的多个硬件资源，对多个硬件资源进行时间分片。此后，可以在与数据处理设备相关联的多个活动硬件资源中分配多个活动硬件资源，从而允许有限数量的硬件资源来服务与数据处理设备相关联的更大数量的物理设备。可以利用一个或多个交换算法从多个活动硬件资源中选择适当的硬件资源。

摘要： The present invention is directed to a method for deterministic Serial Attached Small Computer System Interface (SAS) discovery and configuration. The method includes transmitting a Serial Management Protocol (SMP) DISCOVER Request from a node of a SAS domain to each expander of the SAS domain. The method further includes receiving SMP DISCOVER Responses at the node from each expander of the SAS domain. The method further includes comparing BROADCAST (CHANGE) RECEIVED (BCR) counts provided in each of the received SMP DISCOVER Responses to stored BCR counts, said stored BCR counts having been recorded and stored by the node prior to said transmitting of said SMP DISCOVER Request. The method further includes updating the stored BCR counts based upon said received BCR counts. The method further includes selectively transmitting a second SMP DISCOVER Request from the node to at least one, but not all of the expanders of the SAS domain.
摘要翻译：本发明涉及确定性的串行连接小型计算机系统接口（SAS）发现和配置的方法。该方法包括将SAS域的节点的串行管理协议（SMP）DISCOVER请求发送到SAS域的每个扩展器。该方法还包括在SAS域的每个扩展器的节点处接收SMP DISCOVER响应。所述方法还包括将在接收到的SMP发现响应中的每一个中提供的BROADCAST（CHANGE）接收（BCR）计数与存储的BCR计数进行比较，所述存储的BCR计数在所述发送所述SMP DISCOVER请求之前已由节点记录和存储。该方法还包括基于所接收的BCR计数来更新存储的BCR计数。所述方法还包括从所述节点选择性地向所述SAS域的至少一个扩展器发送第二SMP DISCOVER请求。

摘要： An input port is assigned to a SAS expander device. An output port is assigned to the SAS expander device. The output port and the input port are defined to be paired with each other as a primary subtractive port. Only a SAS initiator address is programmed in the route table of the SAS expander. An OPEN command is sent out the output port upon receiving the OPEN command into the input port if the DEST of the OPEN command is not a direct attached device of the SAS expander device and the DEST is not in the route table of the SAS expander device. An OPEN command is sent out the input port upon receiving the OPEN command into the output port if the DEST of the OPEN command is not a direct attached device of the SAS expander device and the DEST is not in the route table of the SAS expander device.
摘要翻译：输入端口被分配给SAS扩展器设备。输出端口被分配给SAS扩展器设备。输出端口和输入端口被定义为彼此配对作为主减法端口。只有SAS启动器地址在SAS扩展器的路由表中编程。如果OPEN命令的DEST不是SAS扩展器设备的直接连接设备，并且DEST不在SAS扩展器设备的路由表中，则在将OPEN命令接收到输入端口后，OPEN命令被发送出去。如果OPEN命令的DEST不是SAS扩展器设备的直接连接设备，并且DEST不在SAS扩展器设备的路由表中，则在接收到OPEN命令到输出端口时，OPEN命令被发送出去。
