IBM FlashSystem A9000 and IBM FlashSystem A9000R Architecture and Implementation

Book Description

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.

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, refer to the following publications:
