A method comprises obtaining connectivity information from a plurality of electrical devices. Each such electrical device is separately coupled to a backplane, and at least one electrical device comprises a plurality of electrical interfaces adapted to be selectively coupled to each of multiple other electrical devices. Based on connectivity information from the at least one electrical device, the method further comprises providing configuration information to the at least one electrical device to cause the at least one electrical device to electrically couple to a target other electrical device via the backplane.

An embodiment of the present invention provides a peripheral controller for coupling a mass storage peripheral to a computer system. In a disclosed embodiment the peripheral controller is a disk array controller programmed for RAID. The peripheral controller includes a first messaging unit (FMU), a second messaging unit (SMU), and a peripheral interface which are connected by a local bus. The FMU responds to messages from a first operating system driver. The SMU responds to messages from a different second operating system driver. In one embodiment, the FMU responds to commands from the first operating system driver which is non-standard. In another embodiment, the SMU responds to commands from the second operating system driver which is compatible with the I2O standard. In the disclosed embodiment, the peripheral interface controls mass storage peripherals in response to messages sent to the FMU or the SMU.

An isolation system and method that electrically couples a device to a bus during cycles associated with or accessing the device, but otherwise isolates the device from the bus. The isolation system includes an isolation device coupled to the device and to the bus that includes an enable input adapted to receive an enable signal, where the isolation device electrically couples the device to said bus while the enable signal is asserted, but otherwise electrically isolates the device from the bus. The isolation system further includes enable logic that detects cycles on the bus and provides the enable signal to the enable input of the isolation device during a cycle if the cycle is associated with the device. The isolation device may comprise a bus switch, one or more discrete isolating devices such as bipolar transistors, field-effect transistors, or any other suitable device for isolating a device from the bus. Generally, the enable logic may comprise decode logic that decodes an address on the bus during the bus cycle to determine if the address corresponds to an address of the device. Decode logic is usefuil for decoding a memory cycle on the bus for accessing a low voltage memory device, which is otherwise isolated from the bus.

The cage-supported hard disk drives in a computer server system are coupled to connectors on the cage back plane circuit boards and are controlled by a pair of array controller cards which are hot-plug connected in a redundant manner on the system I/O board using a pair of connectors mounted on the I/O board, each connector having first and second sets of electrical contacts thereon. Connector edge portions of the array controller cards are plugged into the I/O board connectors and have first and second sets of electrical contacts that engage the corresponding first and second sets of electrical contacts on their associated I/O board connectors. Formed on the I/O board are (1) a peripheral interconnect bus structure connected to the first sets of connector electrical contacts, (2) an electrical bus structure connected to the second sets of connector electrical contacts and associated cable connectors, and (3) an intercontroller bus structure connected between the second sets of connector electrical contacts and enabling the two array controller cards to communicate with one another independently of the peripheral interconnect bus structure. Electrical cables are interconnected between the electrical bus structure and the back plane circuit boards to couple the array controller cards thereto in a redundant control manner without requiring direct cable connection to either of the array controller cards.
摘要:
The present invention relates to a secondary channel for a point-to-point burst style bus associated with a computer system. The point-to-point bus may originate as a standardized bus from a fibre channel controller. The point-to-point bus connects to another circuit which may be a bridge circuit, a minicomputer or a peripheral device. A secondary channel is also connected to the point-to-point bus and is adapted to share the bus by receiving information having predetermined addresses. The information recieved by the secondary channel can be stored in a memory that is shared with a processor. Command/control information can be extracted from the point-to-point bus before data is transferred through the bridge circuit in order to allow the data to be acted on more quickly by processing/storage devices since the control data was already made available to the storage devices via the secondary channel.
