Method and system for detecting multiple expanders in an SAS topology having the same address

摘要

Methods, systems, and processor-readable media are disclosed for detecting multiple expanders in a SAS topology having the same address. A root expander can be connected to a plurality of expanders, wherein one or more expanders among the plurality of expanders possesses a same SAS address as the root expander. The same SAS address can be identified and stored in a route table against a physical layer identifier through which the expander(s) communicate with the root expander in order to assist in identifying duplicate expanders in the SAS topology.

1. A method for detecting multiple expanders in a SAS topology having the same address: said method comprising:
providing a root expander connected to a plurality of expanders, wherein at least one expander among said plurality of expanders possesses a same SAS address as said root expander; identifying said same SAS address for said at least one expander; and storing the SAS address of said at least one SAS expander in a route table with a physical layer identifier through which said at least one expander communicates with said root expander in order to assist in identifying duplicate expanders in said SAS topology.
