• High performance streaming I/O—reads and writes at up to 2.8 GBps—no RAID6 write penalty
• Dense packaging and capacity—up to 480 TB in a single rack and 960 TB in just two floor tiles
• Extreme reliability—data transfer rates sustained independent of disk or enclosure failures, on-the-fly detection and correction of SATA silent data corruption errors, and RAID6 reliability
• High availability—data access assured independent of disk, enclosure or controller failures
• Simplified management—up to 960 TB in a single management point
• Flexibility—supports SATA drives for capacity or Fibre Channel drives for performance
• Energy efficient—fewer controllers, fans and powers supplies per TB of storage

High performance storage for streaming I/O applications

The IBM System Storage™ DCS9550 Storage System is designed for applications with high-performance streaming data requirements served by Deep Computing systems, IBM System p™ High Performance Computing (HPC) systems, and System x™ 1350 Linux® Cluster systems.


Applications such as those in HPC, rich media, life sciences and government research require high-performance, reliable access to streaming data and extreme capacity and density to simplify management and reduce cost. Examples of such applications include weather forecasting, seismic processing, reservoir modeling, high definition (HD) creation and distribution, proteomics, structural analysis, fluid dynamics and gene sequencing. With its parallel storage solution architecture the DCS9550 is specifically designed to address those needs.

Through its parallel, non-blocking architecture the DCS9550 delivers up to 2.8 GBps data streaming bandwidth from/to disk media whether reading or writing data. As a result, HPC applications are able to write results to disk as they are generated and reduce wait time during check pointing while rich media applications are able to ingest streams and write at full frame rate, even for 4K HD.

With hardware-enabled RAID 6 and inline parity checking and correction, performance is assured even in the event of disk drive or enclosure failures. Silent data errors are fixed on the fly, and disk rebuilds and even missing enclosures are handled without impacting performance.

The DCS9550 saves floor space by supporting up to 960 TB in just two racks and saves energy by doing so with just one controller. Other systems would require many more racks, power supplies, fans and controllers—which means more energy—to support 960 TB.

The IBM System Storage DCS9550 Storage System provides outstanding performance, saves energy and floor space, simplifies management, and increases flexibility for applications with high-performance streaming data requirements.
