The Forrester Wave™: Enterprise Open Systems Virtual Tape Libraries, Q1 2008

Forrester evaluated 12 virtual tape library (VTL) vendors across 58 criteria and found that FalconStor Software leads for the completeness of its product offering and strategy. Fujitsu Siemens Computers leads for its host support, architecture, and tape integration. First-to-market EMC continues to have a very competitive VTL. Quantum shows substantial promise with a VTL that supports both pre- and post-processing deduplication. NetApp has one of the strongest product strategies as it transforms itself into a heterogeneous data protection vendor. Sun Microsystems and COPAN Systems have created unique offerings with partner software and their own intellectual property. SEPATON leads pure-plays with the most complete offering. HP and IBM have improved VTL offerings but lack market traction. Deduplication pioneers Data Domain and Diligent don't integrate with tape but show promise with customers that want tape elimination.
