Abstract: A method and system for maintaining backup copies of firmware. More particularly, embodiments of the present invention provide a method that includes monitoring an execution of at least one firmware component, and causing a backup copy of the at least one firmware component to be generated if the at least one firmware component executes at a predefined standard of reliability for a predefined time period. According to the system and method disclosed herein, trustworthy backup copies are available if a given server of a multiserver system fails.

Abstract: In a computer system having a processor, memory, and a set of storage units storing a set of objects, each object comprising a set of segments arranged in a set of original object stripes on separate storage units, a directory is maintained identifying an object name and a location of each stripe of the object in the set of storage units. A method is provided for re-striping the set of objects onto an expanded set of storage units comprising the set of storage units and at least one other additional storage unit. A list is maintained of each object to be copied onto the expanded set of storage units. Each segment is copied to a new set of stripes on a separate storage unit of the expanded set to create a new object while continuing to store an original copy of each segment of the list object in the original set of object stripes. The directory is updated to include a new object name and a new location of each new stripe of the new object.
