Abstract: A target data storage system is simulated. A source configuration is received. First activity data is received representing workload for the source configuration. A target data storage system configuration for one or more target data storage systems is created. The target data storage system configuration is modeled including determining a simulated workload for components of the target data storage system configuration based on the first activity data. A utilization map is displayed in a user interface indicating component level utilizations of components of the target data storage system configuration based on the simulated workload. A data movement optimization for the target data storage system configuration is simulated. A second utilization map is displayed indicating updated component level utilizations for the target data storage system configuration which have been revised to model the simulated data movement optimization for the target data storage system configuration.

Abstract: A retractable screen is provided for covering a structural opening by mounting it within the opening. The screen comprises a screen panel, first mounting means for mounting the side edges of the screen panel, and second mounting means for mounting the top edge of the screen panel. The first mounting means is further selectively releasably secured to the respective side edges of the screen panel by zipper means such that unfastening the zipper means at both side edges permits the screen panel to be retracted generally upwardly while the mounting means remain generally in place.
