Storage planning and management using a web-based management service

Abstract

We describe a novel approach for the on-line scheduling of storage network access in shared application-hosting environments. Our storage resource management and reservation service (RMRS) dynamically makes advance reservation of storage bandwidth for various accesses while resolving the potential for conflict Unutilized storage network capacity is maintained at an optimal level for being able to support unexpected load/contingencies, while preventing any capacity underutilization. Among the novelties offered by our work are: (1)a web-service architecture (2) an application domain of storage accesses for normal database workload, backup, replication, migration and recovery, while supporting business objectives, QoS, and service-level commitments (3) a formulation of the scheduling problem as a practical Linear Programming (LP) problem comprising a reshaping linearization and integer relaxation of the modeled non-linear bandwidth constraints. © 2007 IEEE.
