System Firmware and Software Update Solution

I've most recently come from a company that used HP servers, and came to know and love the HP Service Packs for ProLiant servers update solution.  This one boot disk provided a comprehensive roll-up of all system software and firmware, all of which could be updated by simply booting the server from this disc/flash drive.  

Is there a similar solution provided by Dell?  I'm going to be doing some off-hour maintenance on a a Dell R510, a PowerEdge 2950, and a PowerEdge 1950 and would love to get these fully patched (especially the DRACs) while I'm at it.  

Thanks!
