Abstract

Many emerging white box storage systems replace mature, robust drive networks with simple point-to-point drive port topologies. The presentation provides fault tolerance where each storage controller has a dedicated port to a drive, but no hardware path to other port(s) to that drive. The redundant access to media is provided via Non-Transparent Bridging (NTB), Ethernet, or other networks to overcome lack of redundancy in the topology

Learning Objectives

Show how to implement an I/O policy management module to reduce / eliminate non-optimal I/O accesses over time,Show user how to provide fault tolerance in storage architecture,How to minimize disruptions when faults occur,Provide automatic drive recovery mechanism,hardware designs will enable software-defined storage (SDS) products and will have lower hardware cost and complexity.
