Abstract

This IBM® Redbooks® describes the concepts, architecture, and implementation of the IBM DS8900F family. The book provides reference information to assist readers who need to plan for, install, and configure the DS8900F systems. This edition applies to DS8900F running microcode Release 9.0 (Bundle 89.0 / Licensed Machine Code 7.9.0.xxx).

The IBM DS8900F family offers two new classes:

- DS8910F: Flexibility Class all-flash
The flexibility class delivers significant performance improvements as compared to the previous IBM DS8880F generation

- DS8950F: Agility Class all-flash
The agility class is efficiently designed to consolidate all your mission-critical workloads for IBM Z®, IBM LinuxONE, IBM Power Systems, and distributed environments under a single all-flash storage solution.

The IBM DS8900F architecture relies on powerful IBM POWER9™ processor-based servers that manage the cache to streamline disk input/output (I/O), maximizing performance and throughput. These capabilities are further enhanced with the availability of the high-performance flash enclosures (HPFE Gen2).
Like its predecessors, the DS8900F supports advanced disaster recovery (DR) solutions, business continuity solutions, and thin provisioning.

The DS8910F Rack Mounted model 993 is described in a separate publication, IIBM DS8910F Model 993 Rack Mounted Storage System, REDP-5566.
