NEC doubles deduplication performance

NEC announced the HYDRAstor HS8-3000 series of target deduplication systems today, which double the throughput of the company’s backup/archiving platforms to 2.7TB per hour per node (750MBps), or up to 148.5TB per hour (41,250MBps) in a high-end HS8-3110 grid configuration, while reducing power consumption by 60% in terms of watts per MB per second.

NEC’s grid-based architecture includes accelerator nodes and storage nodes, which can be scaled independently. Each 2U accelerator node can be configured with six Gigabit Ethernet ports, or with up to four 10GbE and two Gigabit Ethernet ports.

The company’s DataRedux is an inline, global, variable-length deduplication (fingerprinting) technology, as opposed to fixed-length approaches to data deduplication.  Data is compressed after being deduplicated.

Each storage node has 12TB of capacity on 1TB, 2.5-inch SATA drives, or up to 157.5TB when factoring in data deduplication and compression, according to Gideon Senderov, who is in charge of NEC’s product management and technical marketing.

Other features of the HYDRAstor HS8-3000 series include NEC’s Distributed Resilient Data (DRD) technology, which is a form of erasure coding that allows users to mix resiliency levels (up to six) for different applications. The company claims a 150% improvement in data protection vs. RAID 6.

The systems are designed primarily for long-term storage of unstructured data

Pricing for the HYDRAstor HS8-3000 starts at $120,000 for a single-node configuration with 12TB of raw capacity and performance of 2.7TB per hour. A variety of configurations are available, with a high-end HS8-3110 weighing in at 1.3PB of raw capacity, 148.5TB-per-hour throughput, 55 accelerator nodes and 110 storage nodes. Initial shipments are scheduled for Feb. 21.

Options include NEC’s RepliGrid (WAN-optimized replication with encryption), Optimized Copy (WAN-optimized copies for OST), and HYDRAlock (WORM file system).
