Abstract
The invention provides a data storage topology that includes a master logging node where the event logs for all of the nodes may be stored on a consolidated basis. The master logging node is configured with a sufficient amount of reserved or additional data storage to accommodate the event logging requirement for the entire data storage topology. The other expanders in the topology may remain at a baseline model. The master logging medium may be an inexpensive persistent storage, such as a flash chip or USB key. The master logging expander may pull the event logs and other information from the remote expanders or, alternatively, the remote expanders may push their event logs and other information to the master logging node. In particular embodiments, the pull or push configuration may be implemented through preexisting SAS protocols.
