ABSTRACT:
A method and system for implementing a serial enclosure management interface is disclosed. In one embodiment, the LED indicators for a storage device in an external enclosure are managed. First, a set of bit patterns for driving the LED indicators is repeatedly placed on a serial bus that is connected to an external enclosure for transmission by varying the states of the serial bus. This process continues until a change to this set of bit patterns is detected. In one embodiment, the change is captured in a memory mapped register, which is typically accessible by a storage device controller. The detected change prompts accesses to a virtualized register, which generally resides in system memory, to generate a different set of bit patterns to place on the serial bus.
