SVM (Storage Virtualization Manager) is a SAN appliance that provides virtual volume management in heterogeneous environments. The SVM features storage capacity and storage performance pooling across the entire SAN space. Uniquely designed to virtualize storage off the data path, the SVM does not impose any performance penalty and thus delivers highly scalable and highly available SANs at levels not found with traditional approaches. The SVM provides centralized management for distributed enterprise storage, significantly reducing Total Cost of Ownership. It is an ideal platform for SAN-aware Storage Applications such as Remote Mirroring, Snapshot and others and a key enabler for enterprise disaster recovery strategies.
