The DS8880 architecture is server-based. Two powerful POWER8 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). An HPFE Gen2 can now be installed in most models. HPFE Gen2 is described in  IBM DS8880 High-Performance Flash Enclosure Gen2 , REDP-5422.  Combined with world-class business resiliency and encryption features, the DS8880 provides  a unique combination of high availability, performance, and security. The DS8880 is equipped  with encryption-capable drives. High-performance flash drives, high-capacity flash drives, and  solid-state flash drives (SSDs) are available, as well as spinning disk drives. High-density  storage enclosures offer a considerable reduction in the footprint and energy consumption.  Figure 1-2 shows two all-flash configurations: A DS8888 (base frame) on the left side, and a  DS8882 (Rack-mounted model) on the right-hand side. Reduced footprint:  The DS8880 is housed in a 19-inch wide rack. Chapter 1. Introduction to the IBM DS8880  5 Figure 1-2 DS8888F and DS8882F, all-flash systems
