Abstract

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 periphera…
