If you're going to waste your time on a stupid cert, waste it on a vendor cert around your main technology.

I'd trust a RHSE to know redhat security for redhat deployments more than I'd trust a CISSP, mainly because I put close to negative value on the CISSP, and a lot of infrastructure security is actually following best practices, not anything too specific to security.

For networking, Cisco (assuming a Cisco shop).

For virtualization, I've heard the VMware stuff is good if you're enterprise doing VMware. I wonder if there's value in the Amazon AWS courses for AWS deployments; I'd almost take one just to see what they're like.
