High-volume optical archive library

HIT/NETZON’s HSM range are highly reliable near-line mass storage systems which use Blu-ray media of 50, 100 or 128GB, and are optimally organised into magazines each of 35 media, for long-term and optimised energy-efficient data management (Green IT). The smaller range of HIT archive storage has systems of 35 media (HMS 1035), 105 media (HMS 2105), 350 media (HMS 3350) and 560 media (HMS 3560).

The latest model from the HMS range: the “5175”

The new HMS 5175 model, with 1750 media, has unique properties, making the system especially suitable for long-term data storage for the analysis of Big Data, but also as secure data storage for the archiving of sensitive and business-critical data. The HMS 5175 media library can be used with a maximum of 12 drives and is thus able to transfer to optimal media at a rate of up to 280MB/sec. The in-built NAS server has a hard drive cache, which is intelligently managed by the library software and is also designed to be fail-safe, thanks to redundant power supplies.

These systems enjoy minimal energy consumption (COLD storage) compared to other storage systems. The robust mechanics (HIT archive robots have been in use for 20 years now), and the innovative magazine technology, ensure long-term access to databases. The separation of data carriers and drives also ensures against data loss. Professional BD media are certified for a lifespan of 50-100 years and thus significantly reduce migration costs.
