IBM DS8000 series


The IBM DS8000 series is an IBM storage media platform with hybrid flash and hard disk storage for IBM mainframes and other enterprise grade computing environments.

Description

This series was formerly designed as a line of cabinet-size solutions, prior to the more compact and affordable rack-mount DS6000 series. In 2015 the DS6000 line were discontinued, and the all-flash entry-level DS8882F model was released as a rack-mount successor of DS6000 line.
All IBM DS storage lines are based on an IBM Power CPU and use IBM Power Systems servers as controllers.
