Techniques are provided for optimizing bandwidth in a network. Information describing a network bandwidth capacity of a port extender device is received at a switch. The port extender device is connected to the switch. The port extender device is configured to provide ports for the switch. The network bandwidth capacity of the port extender device is compared to a minimum network bandwidth guarantee threshold. If the switch determines that the network bandwidth capacity of the port extender device is below the minimum network guarantee threshold, the switch sends to the port extender device a message configured to cause the port extender to deactivate one or more links between the port extender device and one or more servers in communication with the port extender device.

A system and method for parallel file system traversal using multiple job executors is disclosed. The system includes a pool of job executors, a job queue, and a trigger tracker. An object, representative of a node in the filesystem, is added (i.e., pushed) to the job queue for processing by an job executor. The job queue assigns (i.e., pops) objects to job executors in accordance to a LIFO (Last In First Out) ordering. Then the job executor performs an action such as copy. In one embodiment, the trigger tracker follows the processing of a child nodes to a particular child node. Thus, the filesystem is being traversed by several job executors at the same time.
