-- Nexsan Technologies and FalconStor Software are teaming up to deliver a co-branded data deduplication system with energy-saving AutoMAID technology for Nexsan storage environments.
Introduced this week, the Nexsan DeDupe SG ("Speed with Green") product family combines FalconStor's File-interface Deduplication System (FDS) with Nexsan's SATABeast or SATABoy disk arrays. FalconStor's FDS is a block-level deduplication software engine that presents a network share interface as a backup repository and works with all data sources, including disk-to-disk backup and archiving applications.
The systems can be deployed in physical or virtual infrastructure environments, offering file-level access to a central block-level deduplication repository.
The Nexsan DeDupe SG family uses policy-based concurrent and post-process deduplication and supports all major backup software; directly accepts Oracle RMAN, Microsoft SQL and other database dumps; and provides integrated data replication and deduplication.
However, there is one catch: the DeDupe SG is specifically built to work with and deduplicate data in Nexsan storage environments, according to Bob Woolery, Nexsan's senior vice president of marketing.
Woolery says the Nexsan-FalconStor combination does more than reduce the cost of storage hardware through deduplication.
"The original driver for deduplication was to reduce storage capacity and the cost of disk. We've taken that a step further to create a solution that reduces operational expenses by applying our AutoMAID energy saving technology when the system is not in use," says Woolery.
AutoMAID offers three different levels of energy savings, each with its own performance metrics. Level 1 parks the drive head for a power savings of 20% with data response times of less than 10 seconds, and once the first file is accessed the disks perform at full speed. At level 2, AutoMAID slows down the drives to 4,000rpm for energy savings of up to 40% and response times of 15 seconds or less. The third level puts drives into what Woolery calls a "light sleep," yielding up to 60% energy savings. Once the drive comes out of its level-three nap, the first I/O transaction takes 30 seconds or less.
The Nexsan DeDupe SG is available in several different models at different capacity points, ranging from a starting configuration of 4TB of usable storage up to the 52TB DDSG-52. Logical capacity for the DDSG-52 maxes out at just over 1PB.
Pricing for an entry level 4TB DDSG-4 starts at about $49,000. The 52TB model retails for about $300,000.
