Synopsis:
In enterprise environments fault tolerance, redundancy, and high
throughput are all major concerns. And there are few places where
these concerns are as pressing as they are for enterprise storage.
Multipath is a storage technology that fulfills all of these
requirements and Device Mapper Multipath is a native multipathing
solution for Linux systems. Though Device Mapper Multipath is mature,
stable, and widely deployed it is often misunderstood and incorrectly
deployed.

This presentation explains Device Mapper Multipath starting at theory
of operation, to deployment, and finally through troubleshooting. The
goal of the presentation is to provide a clear and complete
description of how to deploy, understand, and resolve issues with
Device Mapper Multipath on Linux systems. The material will be
presented with a focus on Device Mapper Multipath on Red Hat
Enterprise Linux 5 and Red Hat Enterprise Linux 6 but is  also
applicable to Fedora, CentOS, Scientific Linux, and other
Fedora-derived distributions.
