Implementing IBM FlashSystem 840

Book Description

Almost all technological components in the data center are getting faster; central processing units, network, storage area networks (SAN), and memory. All of them have improved their speed by a minimum of 10X; some of them by 100X, for example, data networks. However, spinning disk performance has only increased by 1.2 times.

The IBM FlashSystem™ 840 closes this gap. The FlashSystem 840 is optimized for the data center to enable organizations of all sizes to strategically harness the value of stored data. It provides flexible capacity and extreme performance for the most demanding applications, including virtualized or bare-metal online transaction processing (OLTP) and online analytical processing (OLAP) databases, virtual desktop infrastructures (VDI), technical computing applications, and cloud environments. The system accelerates response times with IBM® MicroLatency™ access times as low as 90 µs write latency and 135 µs read latency to enable faster decision making.

The introduction of a low capacity 1 TB flash module allows FlashSystem 840 to be configured in capacity points as low as 2 TB in protected RAID 5 mode. Coupled with 10 GB iSCSI, FlashSystem is positioned to bring extreme performance to small and medium-sized businesses (SMB) and growth markets.

Implementing the IBM FlashSystem 840 provides value that goes beyond those benefits that are seen on disk-based arrays. These benefits include better user experience, server and application consolidation, development cycle reduction, application scalability, data center footprint savings, and improved price performance economics.

This IBM Redbooks® publication introduces clients to the IBM FlashSystem. It provides in-depth knowledge of the product architecture, software and hardware, its implementation, and hints and tips. Also illustrated are use cases that show real-world solutions for tiering, flash-only, and preferred read, as well as examples of the benefits gained by integrating FlashSystem storage into business environments.

Also described are product integration scenarios running the IBM FlashSystem 840 with the IBM SAN Volume Controller, the IBM PureFlex® System, and the IBM Storwize® V7000, as well as considerations when integrating with the IBM FlashSystem 840. The preferred practice guidance is provided for your FlashSystem environment with IBM 16 Gbps b-type products and features, focusing on Fibre Channel design.

This book is intended for pre-sales and post-sales technical support professionals and storage administrators, and for anyone who wants to understand and learn how to implement this new and exciting technology.
