Disclosed herein is an electronic device network for lifecycle management of firmware and software in electronic devices. According to an embodiment of the present invention, simulators are interfaced to a simulation backplane via simulator-dependent interfaces. Agent types include a smart agent, a search agent, a custom agent for detailed tasks and an RSS agent for retrieving structured XML format documents from remote Internet sites. Methods and apparatus are also provided for generating one or more images depicting the profile of the ablated region of the cornea. The second write block size is maintained if the performance parameter exceeds a threshold. Desired queue depth of each disk may be associated with performance factors including, but not limited to, inputoutput operations per second, average response time, andor maximum response time of each disk.
