As I mentioned yesterday, one of my fellow bloggers, Stephen Foskett, is writing a series on blade servers.  His latest post reveals the history of the blade server.  Stephen’s article challenged me to do some research of my own – and here’s what I found.   Apparently the first “official” patent for a server on blade (patent # 6,411,506 – “High density web server chassis system and method) was awarded in June of 2002 to Christopher G. Hipp and David M. Kirkeby of RLX Technologies.   One interesting fact is that U.S. Patents referenced within the document refers to other patents from many leaders of the industry including IBM, Hewlett-Packard, Micron, Hitachi and even Dell.

I’ve taken the liberty of downloading the entire patent document for your reference:
High Density Web Server Chassis – Patent 6411506 B1 (1.84Mb, PDF).

If you like technology and are a history buff, I recommend you check out Stephen’s article at http://blog.fosketts.net/2012/02/20/blade-server-history/.
