NAND Flash-based Solid State Storage Performance - An In-depth Look
Jonathan Thatcher
Download

This tutorial provides an in-depth examination of the fundamental theoretical performance, capabilities, and limitations of NAND Flash-based Solid State Storage (SSS). The tutorial will explore the raw performance capabilities of NAND Flash, and limitations to performance imposed by mitigation of reliability issues, interfaces, protocols, and technology types. Best practices for system integration of SSS will be discussed. Performance achievements will be reviewed for various products and applications. Several examples of successful enterprise deployments with comparative performance and cost-performance will be presented.

Learning Objectives

  • Gain working knowledge of NAND Flash SSS types and deployments with associated performance capabilities
  • Understand the benefits and ROI of deploying SSS in different application spaces
  • Know key factors to explore with vendors while planning SSS deployment

Storage Class Memory - the Future of Solid State Storage
Phil Mills
Download

This tutorial describes ten new technologies currently under development in research labs around the world that promise to replace today's NAND Flash technology. These new technologies - collectively called Storage Class Memory (SCM) - provide higher performance, lower cost, and more energy efficient solutions than today's SLC/MLC NAND Flash products. In this tutorial we extrapolate SCM technology trends to 2020 and analyze the impact on storage systems. The material is intended for those people that are closely watching the impact to the storage industry - brought about by NAND Flash - and want to understand what's next.

Learning Objectives

  • Understand the basic ideas behind today's research into the new set of technologies called Storage Class Memory
  • Understand the differences between today's NAND Flash and SCM
  • Understand the likely impact of SCM on our future storage systems

Solid State Storage in a Hard Disk Package
Brian McKean
Download

For those interested in considering flash based SSD as a replacement for hard disk drives in storage systems, this tutorial will provide some things to look at as part of that process.  While using the same form factor and interfaces as Hard Disk Drives, SSDs have a greater variation in features and performance.  Without discussing specific vendors, this tutorial will show examples of these variations and discuss how they affect using the drives in storage systems.

Learning Objectives
• Learn some of the ways SSDs differ from HDDs and from each other
• Understand some of the things to look at when considering deploying SSDs

Solid State Storage Reliability and Data Integrity:  An In-depth Look
Jonathan Thatcher
Download

This tutorial provides an in-depth examination of NAND Flash as a storage medium and control techniques used to ensure enterprise-grade Solid State Storage (SSS) reliability and data integrity. Several aspects of the topic are discussed, including reliability characteristics unique to the medium (e.g. wear out, shelf life, early life failures, failure modes), and implications for architecture, implementation, system integration, and deployment of NAND Flash-based SSS. These topics will be reviewed with a focus on device failure rates, data integrity, and data availability. A taxonomy of components is also presented as related to reliability, including what to look for in different classes of products. Finally, recommendations will be made regarding best practices, and information that users should obtain from potential vendors to properly assess SSS device reliability and data integrity.

Learning Objectives
• Gain working knowledge of NAND Flash medium characteristics and controller techniques used to ensure reliability and integrity
• Understand the basic probability and statistics behind solid state storage
• Know how to incorporate SSS into your systems and applications while meeting quality targets

Economics of Solid State Storage: Perception and Reality

This tutorial will explore how solid state storage (SSS) when appropriately deployed and configured offers cost benefits that will accelerate into the future. The presentation will introduce the application-based Return on Investment (ROI) formula that has driven SSS deployments until recently. Though this formula is still operative in many enterprise environments, the falling price of Flash SSS is driving ever increasing Total Cost of Ownership (TCO)-based SSS deployments. The tutorial will review SSS value vectors, overview server workloads and usage models where SSS can yield lower TCO, and introduce a user-oriented TCO model allowing enterprise assessment using end user specifications and input
