Summary
For those of us still configuring physical servers and storage, using RAID to ensure the availability of storage is part of our everyday jobs. But things are changing rapidly in the types of storage devices being used, as well as their characteristics. Standard RAID techniques may carry consequences that solution architects may not realize are present.

This talk will examine the beginnings of RAID, how we got to where we are at now, and some of the issues that currently exist with RAID. Alternate techniques (including open source solutions) can provide more resiliency with fewer gotchas. There will also be a quick tutorial on "fio", the flexible I/O tester.
