Demartek Report: FalconStor Virtual Tape Library (VTL) and Deduplication Performance
sponsored by FalconStor Software

Virtual tape libraries (VTL) are a key technology that can save a considerable amount of time and storage capacity in the data center by utilizing disk storage that presents itself as a tape library solution. VTLs typically work seamlessly with enterprise backup software and help reduce the amount of time backup operations consume. VTL solutions often bring compression, single-instance store and data deduplication functions that help reduce the total amount of storage capacity required for backup and related activities. VTLs can make a direct positive impact on the backup window as well as recovery time objectives (RTO) and recovery point objectives (RPO).

Some of the key metrics of VTL solutions are their sustained rate of I/O during backup operations and during data deduplication operations.

To evaluate the performance of its solutions, FalconStor commissioned Demartek to validate the performance of the FalconStor VTL solution and its deduplication solutions, as they come from the factory, without any special tuning adjustments. The sustained performance of these solutions is impressive, and was measured using conservative data intended to be typical of many enterprises.

During the testing, Demartek measured the speed of the I/O operations and the data savings achieved using the compression features of the FalconStor VTL solution and the deduplication features of the FalconStor SIR solution.
