IBM System Storage DCS3860 is the next generation in controller technology designed to meet the need for rigorous, scalable bandwidth requirements to remain productive for high-performance streaming applications, such as high-performance computing, rich media, weather forecasting, seismic processing, or life sciences research.

The DCS3860 is an affordable storage platform capable of supporting up to 60 drives within a slim 4U enclosure. A complete DCS3860 system configuration consists of one DCS3860 controller and five EXP3800 Expansion units. Since each EXP3800 Expansion unit supports 60 drives, a complete DCS3860 system can scale up to 360 drives. With 4 TB high-capacity nearline SAS disk drives, the DCS3860 can deliver up to 1.44 PB of physical capacity within a 24U space. The controller and the expansion unit support intermixing of SSD, high-performance SAS, and nearline SAS drives. A DCS3860 storage system can support a maximum of 24 SSDs.

Standard memory cache on the DCS3860 is 24 GB, with 12 GB per controller. The storage system provides eight 6 Gb SAS host interfaces (four per controller), and provides performance read cache to enable the utilization of SSDs for accelerating reads from the storage, helping to increase performance for analytics and high performance computing environments.

In order to ensure data integrity, the DCS3860 provides flexible levels of RAID protection (0, 1, 3, 5, 6 and 10), and also includes DDP for simplified installation, greater data protection, and more consistent performance than traditional RAID options.
