Anyone here an HP customer with Proliant servers?

Why that would be me. And ours are purple.

If you called in to tech support, and asked the guy what your servers were running, and his answer was "A mixture of Windows and Linux", what would your response be?

I'd say you have too many Windows machines. Actually, my gripe with HP and OS's is that even though you're now distributing Mandrake on the desktop machines, the Proliant guys still can't figure out that Redhat != Linux. Just try to get the health monitor or Insight agent running under Debian.
