## 1.1 Introduction to the IBM DS8900F 

The IBM DS8000 family is a high-performance, high capacity, highly secure, and resilient series of disk storage systems. 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.

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.
