IBM FlashSystem A9000 and IBM FlashSystem A9000R Architecture and Implementation

Book Description

Abstract

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 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.

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

For detailed information about configuration, management, and replication functions and their usage, see the following publications:
