March 23, 2009 -- Data Domain expanded its line of de-duplicating disk-based backup products with the introduction of the DD660, a quad-core processor system that offers a 50% increase in both speed and capacity over its dual-core predecessor.

The new midrange DD660 supports up to 2TB/hour of aggregate inline de-duplication throughput and up to 700GB/hour for a single stream.  It also supports up to 36TB of raw capacity, which translates to 1.3PB of logical capacity with 50:1 data reduction.

The base model, which supports 1TB disk drives, includes 12TB in a 2U rack-mount chassis. The company now supports 1TB disk drives in the base model DD660 and in all expansion shelves for both the DD660 and DD690.

The DD660 connects to fabrics using NFS, CIFS and NetBackup OpenStorage (OST) over Gigabit Ethernet (GbE) or 10GbE and/or VTL over 4Gbps Fibre Channel.  

Data Domain's modus operandi is to follow the CPU curve by adding performance and scalability as new processors are made available. This allows the company to speed up its systems without "throwing drives at them," according to Beth White, Data Domain's vice president of marketing.

The launch of the DD660 comes on the heels of a new version of the Data Domain operating system (DD OS) released earlier this month. The DD OS 4.6 software reportedly boosts performance across the company's line of de-duplicating disk-based backup systems by as much as 100%.

The DD OS uses a proprietary technology called Stream Informed Segment Layout (SISL) to achieve high throughput while minimizing system and disk hardware. The software is CPU-centric and can be used to upgrade performance without adding controllers, compression hardware or disks.

The DD660 is available at roughly the same price as its predecessor, the DD580, with a starting price of approximately $120,000.
