Over the last eighteen months, Easy Tier has helped numerous DS8700 and DS8800 clients achieve dramatic gains in performance and storage efficiency for their production environments. This paper examines the third generation of Easy Tier which is available with Licensed Internal Code (LIC). This update further expands Easy Tier to manage hybrid storage pools with up to three tiers including Solid State Drives (SSDs), Enterprise Disks, and Nearline Disks. The Easy Tier management algorithms have been enhanced to optimize capacity utilization of both SSD and Nearline tiers.
