Storage Area Networks (SANs) connect groups of storage devices to servers over fast interconnects. An important challenge lies in managing the complexity of the resulting massive SAN configurations. Policy-based validation using new logical frameworks has been proposed earlier as a solution to this configuration problem. SANchk offers a new solution that uses standard technologies such as SQL, XML, and Java, to implement a rule-based configuration checker. SANchk works as a light-weight extension to the relational databases of storage management systems; current support includes IBM's TPC and the open source Aperi storage manager. Some five dozen best practices rules for SAN configuration are implemented in SANchk, many of them with configurable parameters. Empirical results with several commercial SANs show that the approach is viable in practice.
