MD cluster is a host based raid device. It can avoid single point of failure and provide HA storage for a HA cluster.
In this presentation, I'll talk the following points:
1) The coming availability of MD Cluster RAID
2) What is it and what could it be used for? (e.g. active / active cluster file systems like GFS, multi-site high-availability)
3) How it works and a bit about the technologies it relies on (e.g. DLM)
_x005F*) this might include some explanation of what each layer needs to protect in a cluster setting
4) history - comparisons to cmirror and how/why MD cluster RAID evolved
5) perhaps a demo depending on time
