Abstract

The migration from hard disk drives to Solid-State-Drives (SSDs) bears the promise of increasing random access time by multiple orders of magnitude. This presentation explores the impact of this change on optimal architectures of storage systems, including tiering and auto tiering, caching, redundancy and Redundant Array Inexpensive Disks (RAID), and presents new methods for optimal usage of inherent capabilities of NAND Flash, including wear-level mechanisms and new redundancy approaches.

Learning Objectives

Tiering and auto-tiering in SSD-based storage systems
Caching and endurance impact on NAND-based systems
Wear-level, hot/cold areas in the SSD and auto-tiering
Classical Redundancy and new approaches to redundancy and RAID in Flash-based systems
