    • A management sub-system is associated with a host computer system. The host system includes a network interface controller to facilitate transmissions between the host system and a distributed computer network. In addition, the management sub-system and host computer share an Ethernet network interface controller (NIC), which is assigned at least two different addresses. The management NIC includes decode logic that detects either of the addresses assigned to it, and routes the associated data packet to the management processor, or to the host processor. As a result, all management operations to either the management sub-system or the host system may be routed through the management NIC, while other standard operations may be routed through the host NIC. In addition, the management NIC may be used as a back-up or spare for the host NIC in the event it fails, or becomes overly busy.
    • 管理子系统与主机系统相关联。 主机系统包括网络接口控制器,以便于主机系统和分布式计算机网络之间的传输。 此外,管理子系统和主机共享一个以太网网络接口控制器(NIC),它被分配至少两个不同的地址。 管理NIC包括检测分配给它的地址中的任何一个的解码逻辑,并将关联的数据分组路由到管理处理器或主机处理器。 因此,管理子系统或主机系统的所有管理操作可以通过管理NIC进行路由,而其他标准操作可以通过主机NIC进行路由。 此外,管理NIC可能会在主机NIC发生故障或过度忙碌时用作备用或备用主机NIC。

    • A management sub-system connects via a USB bus to a server or computer being managed. The management sub-system also couples to a management console, which has a number of conventional peripherals, including CD-ROM, floppy drive, hard disk, keyboard, mouse, and the like. These peripherals are emulated as USB peripherals coupled to the server by the management sub-system. The management sub-system includes a Composite USB function logic device that connects to the USB controller in the server. The Composite USB function logic device emulates the various peripherals available at the management console, and provides configuration data to the USB controller consistent with the emulation. Consequently, the server sends and receives data from these peripherals at the management console, as if the peripherals were locally connected by the USB bus to the server. The management sub-system monitors the operation of the server and publishes a web page that can be viewed by a web browser at the management console. In addition to viewing this status information, the management console can operate as a virtual terminal, capable of downloading files and programs from any of the emulated peripherals to the server, and of receiving input signals from the emulated input devices.
    • 管理子系统通过USB总线连接到被管理的服务器或计算机。 管理子系统还耦合到具有许多常规外围设备的管理控制台,包括CD-ROM,软盘驱动器,硬盘,键盘,鼠标等。 这些外设被仿真为由管理子系统耦合到服务器的USB外设。 管理子系统包括连接到服务器中的USB控制器的复合USB功能逻辑设备。 复合USB功能逻辑器件模拟管理控制台上可用的各种外设,并将配置数据提供给符合仿真的USB控制器。 因此,服务器在管理控制台从这些外设发送和接收数据,就好像外设通过USB总线本地连接到服务器。 管理子系统监视服务器的操作,并发布可由管理控制台上的Web浏览器查看的网页。 除了查看该状态信息之外,管理控制台可以作为虚拟终端来操作,能够将文件和程序从任何仿真外设下载到服务器,以及从仿真的输入设备接收输入信号。
