* Version 12.3 *

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 powerful compression engine, help lower total cost of ownership. The Hyper-Scale Manager highly intuitive user interface simplifies management.

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 IBM 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 IBM XIV® Gen3. With Software version 12.2.1, cross-generation Hyper-Scale Mobility allows online volume migration from XIV Gen3 to FlashSystem A9000 or A9000R.

Version 12.3 introduces support for a multi-site HA/DR solution and a new entry level configuration hardware for the A9000R.

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