Campus grid storage service is to aggregate the storage resources voluntarily contributed by the servers in the campus network, and the storage resources in personal computers (PC) to provide the services of register, allocation, scheduling, free allocation for uses through building three level storage architecture. The voluntary nodes contributed storage resources and the users explore the storage resources according to some rules. The problem of resources sharing under this condition is a NP-complete problem. To solve it, we propose the greedy heuristic algorithm, and simulate the system performance. Finally the relation between storage resources users' requests and system load is gotten.
