摘要:
A method to provide a signal using a communication link. The method disposes a passive transponder on the communication link, where that passive transponder includes a memory. The method reads information relating to the communication link from the memory, and then, based upon that information, adjusts certain characteristics of a signal provided using the communication link.

A firmware update system includes a high-level management device implementing high-level management software application that selects a redundant embedded processor as a master sub-system. Firmware update images are transmitted to the master sub-system over a primary communication path. The master sub-system re-distributes the firmware update images to other associated redundant embedded processors over secondary communication paths. This reduces communication-bandwidth utilization over direct communication paths between the high-level management system and the other associated redundant embedded processors.

An apparatus, system, and method are disclosed for performing a storage device maintenance operation. A management module receives a command through an interconnection module configured as a non-blocking switch. The management module performs a maintenance operation on a storage device through the interconnection module in response to the command. In addition, the management module may receive queries on the status of the maintenance operation through the interconnection module and report the status of the maintenance operation through the interconnection module.
摘要:
An indicator light, such as an LED, for a computer disk drive module is controlled via an external controller. The disk drive module monitors a disk drive and determines a desired state of the LED, such as on, off or flashing, to indicate a status of the disk drive. The disk drive module provides a modulated signal carrying data that identifies the desired state on a path coupled to the indicator light and a terminal that is accessed by the external controller. The controller implements an algorithm for driving the indicator light, where the algorithm receives, as a first input, the desired state determined from the demodulated signal and, as a second input, information obtained from monitoring the disk drive module. The controller itself may obtain this information or receive it from a higher-level system controller.
