HP StorageWorks SDLT 160/320 Tape Drive

The HP StorageWorks SDLT Tape Drive is a high-capacity, high-performance streaming tape drive designed for use with HP ProLiant servers, HP AlphaServers, and Open SAN storage systems. The tape drive uses Laser Guided Magnetic Recording (LGMR) technology to maximize the amount of data that can be stored on a tape. The SDLT uses a clustered magnetic-resistive (MR) head technology to improve data density, uses Partial Response Maximum Likelihood (PRML) technology to provide increased performance, and has a robust tape buckling system for reliability.

The SDLT 320 is for HP customers who use Corporate-to-Enterprise servers and require higher performance, greater capacity and enterprise class reliability. The HP StorageWorks SDLT 320 GB Tape Drive extends the advantages of an SDLT-based data protection solution by increasing capacity and performance by 45%. Total costs of ownership are significantly lowered by reducing the number of data cartridges required and by shrinking the backup window for business-critical data. In addition, backward-read compatibility to existing DLT and SDLT-based solutions provides the highest level of investment protection while offering a smooth transition path to new SDLT 320-based data protection solutions. The SDLT 320 offers the same backward-read compatibility to current DLT tape drives as the SDLT 220, but is also write-compatible with the SDLT 220 and utilizes the same DLT1 media and cleaning cartridge.
