My name is Vinny Valdez. I am a Red Hat employee. Prior to working for Red Hat I was a Dell employee for 5 years. For the last year and a half I have been working with Dell Engineering to certify and document Red Hat clusters running on Dell PowerEdge servers and PowerVault/EqualLogic storage.
Documentation is here Dell|Red Hat HA Linux Cluster
I amso helped develop an automated scripting solution for initializing clusters called dell-config-cluster
Here's a video that was taken of me when I was a Dell employee at Red Hat Summit for an RHCE Tip for firewall configuration.
