Abstract: A system and method for evaluating workload units in a computer system whereby each workload unit is assigned an impact number representing the number of days that the expiration date of a computer system would be changed if the workload unit were to be added or removed from the system with all other workload units remaining the same. Each workload unit may be assigned a different number for each system in the environment. The inventive system and method simplify the task of combining multidimensional workload measures and incorporate the interaction with other workload units in the system by assessing the impact on both a donor and a recipient computer systems' expiration dates. Thus, the invention provides a more robust way to measure the effect of moving workload units between systems to result in a better allocation of work amongst computer systems in a processing environment.

Abstract: A method, system, and computer program for managing multi-tiered resource systems, such as Storage Area Networks (SANs). Resource tiers in the resource system are examined to if they are in compliance with a management policy. If a resource tier is not in compliance with the management policy, a processing operation automatically increases available capacity in containers in order to bring the containers in compliance with the management policy. The management policy may, for example, include a requirement that an expiration date of the resource tier occur after a maintenance date.

Abstract: A system and method for projecting capacity of computer resources for a plurality of processing systems in a processing environment and for adjusting workload among said systems to improve resource utilization. An administrative processor determines the projected usage of computer resources for a plurality of computer systems in a processing environment by representing the capacity of each of the plurality of computer systems in a normalized unit and by sorting the capacities of the computer systems by the normalized or standardized units. The standardized unit, optimally time as measured as the life expectancy of each different resource of the computer system, is used for the N-axes of the N-dimensional space called a capacity space. Each computer system is mapped to a point in the capacity space, which normalizes configuration and capacity differences between systems by expressing the usage of all resources in the units of time.

Abstract: A system and method for managing storage resources in a computer system. The invention periodically tracks and stores the history of each object stored in the storage resources. For each storage container, the life expectancy is calculated by utilizing the object histories for all objects currently stored in that container.

Abstract: A system for providing a centrally planned, completely general routing system that assigns traffic routes to maintain optimal traffic system stability. The system includes a plurality of fixed computers, linked by a wide area network, which can communicate seemlessly with all vehicles in a region via a wireless communication system. The system is interactive, in that the fixed computers receive data such as desired route, position and segment transit time data from individual in-vehicle computer units and determine and communicate the system optimal route to each such in-vehicle unit.
