EMC releases new midrange deduplication array

Data Domain DD670 is twice as fast as its predecessor, scales to 76TB

EMC announced three new products, including a new midrange Data Domain deduplication appliance, a new disk archive system with deduplication for mainfames and a disk library series with arrays that scale from 8TB to 1.4PB.

EMC's new deduplication storage system, the Data Domain DD670, offers the fastest data compression to date with up to 5.4TB per hour of inline deduplication throughput.

The DD670 The system scales to 76TB of raw data capacity and 2.7PB of logical capacity with a data reduction rate of up to 50 times depending on the type of file or block-level data being used, EMC said.

The new DD670 also increases the number of remote arrays that can replicate back to a Data Domain deduplication device over a WAN. Up to 90 arrays can replicate back to the DD670 compared to 60 on EMC's previous Data Domain DD630 array.

"Take a bank for example. It can have many branch offices. Each branch needs local backup and recovery, but you also need disaster recovery," said Shane Jackson, senior director of product marketing for EMC Backup Recovery Systems.

"This allows you to replicate each of those boxes back to a central data center for disaster recovery," he said.

The base model of the DD670 includes 12TB of disk capacity in a 2U (3.5-in) rack mount chassis, and supports expansion shelves with either 1TB or 2TB SATA drives. No matter the drives used, however, the DD670 base model only holds 12TB.

The DD670 supports a range of applications and file transfer protocols including Network File System (NFS), Common Internet File System (CIFS), as well as Symantec OpenStorage or EMC Data Domain Boost over Gigabit Ethernet or 10Gbit/sec. Ethernet and/or Fibre Channel.

An 8 Gbit/sec. Fibre Channel connectivity option is also now available for the DD670 and DD880. Pricing for the DD670 starts at $110,000.

EMC also announced an data deduplication expansion unit for its existing DLm960 (Disk Library for mainframe) product . The expansion unit is based on the Data Domain DD880 deduplication storage system, which now allows mainframes to reduce data transfers during backup and archive workloads.

The DLm960 with the Deduplication Storage Expansion looks like a tape library to an application backing up to it. It can scale from 2 to 6 virtual tape library engines (disk backup devices that mimic tape drives) and supports up to 12 Ficon (Fibre Connectivity for mainframes) connections.

The Dedupliation Storage Expansion option with DLm960 has an data ingest rate of 4.3TB per hour and can store up to 3.5TB of data on each physical box, but it can scale up to 3.5 petabytes of logical data. The box also allows WAN replication to other DLM960s for disaster recovery.

The DLm960 uses serial ATA (SATA) drives with RAID 6 (dual disk failure) protection.

EMC also announced a new Disk Library series of arrays. The 5000 Series scales from 8TB to 1.4 petabyts of usable capacity with up to 2.8 petabytes of logical capacity. The new Disk Library 5000 has an average data compression rate of 2:1 and can ingest up to 10.2TB of data per hour.

The two models in the DL5000 series, the single-engine DL5100 and the dual-engine DL5200, consist of one and two Disk Library engines, respectively, with Clariion CX4-240 or CX4-960 arrays on the backend.

The new disk library engines are based on Intel Xeon Processor 5500 Series. The disk libraries include three 8 Gbit/sec. Fibre Channel ports. The dual engine DL5200 offers active engine failover for high availability.

Like all EMC Disk Library systems, the new DL5000 series includes advanced virtual tape functionality, which allows it to act as a VTL. The functionality includes disk spin down for increased power savings and disk longevity.

Pricing for the DL5100 starts at $204,000 and $390,000 for the DL5200.
