Abstract

This IBM® Redpaper™ publication explains how to select an IBM FlashSystem™ or solid-state drive (SSD) solution. It describes why and when to use FlashSystem products, and reviews total cost of ownership (TCO), economics, performance, scalability, power, and cooling. Read this guide for information about selecting the correct solution (SSD or flash technology).

This paper also reviews examples of FlashSystem storage bundled with solutions such as hybrid arrays and IBM System Storage® SAN Volume Controller (SVC, a member of the IBM Storwize® family). Furthermore, it compares FlashSystem storage to other storage such as PCIe Express (PCIe) products and hard disk drives (HDDs).
