The DS8900F family is the latest and most advanced of the  DS8000 offerings to date. The high availability, multiplatform support, including IBM Z, and  simplified management tools help provide a cost-effective path to an on-demand world. The IBM DS8900 family consists of the following high-performance models:  GLYPH<SM590000> DS8910F: Flexibility Class, rack-mounted GLYPH<SM590000> DS8910F: Flexibility Class, racked GLYPH<SM590000> DS8950F: Agility Class The DS8900F models support the most demanding business applications with its exceptional  all-around performance and data throughput. Some models are shown in Figure 1-1. Figure 1-1 DS8900F frame (standard doors, with side covers) The DS8000 offers features that clients expect from a high-end storage system: GLYPH<SM590000> High performance GLYPH<SM590000> High capacity GLYPH<SM590000> High availability GLYPH<SM590000> Cost efficiency GLYPH<SM590000> Energy efficiency GLYPH<SM590000> Scalability GLYPH<SM590000> Business continuity and data protection functions The DS8900F architecture is server-based. Two powerful POWER9 processor-based servers  manage the cache to streamline disk I/Os, maximizing performance and throughput. These  capabilities are further enhanced with the availability of high-performance flash enclosures  (HPFEs). HPFE Gen2 is described in  IBM DS8000 High-Performance Flash Enclosure Gen2 ,  REDP-5422.  4  IBM DS8900F Architecture and Implementation
