This edition applies to FlashSystem A9000 and A9000R , Model 415 and 425 with Storage Software Version 12.2

This IBM® Redbooks® publication presents the architecture, design, concepts, and technology that are used in IBM FlashSystem® A9000 and IBM FlashSystem A9000R.
FlashSystem A9000 and FlashSystem A9000R deliver the microsecond latency and high availability of IBM FlashCore® technology with grid architecture, simple scalability, and industry-leading IBM software that is designed to drive your business into the cognitive era.

Comprehensive data reduction capabilities, including inline deduplication and a new compression engine, help lower total cost of ownership, and a highly intuitive user interface simplifies management. FlashSystem A9000 and FlashSystem A9000R transform technology infrastructure into business innovation.

From a functional standpoint, FlashSystem A9000 and FlashSystem A9000R take advantage of most of the software-defined storage features that are offered by the IBM Spectrum™ Accelerate software, including multi-tenancy and business continuity functions. Starting with software version 12.1, the HyperSwap® feature delivers always-on, high availability (HA) storage service for storage volumes in a production environment. Software version 12.2 introduces cross-generation asynchronous mirroring with XIV Gen3.

This publication is intended for those individuals who need to plan, install, tailor, and configure FlashSystem A9000 and FlashSystem A9000R.
