*nods* I've seen half and third cabinet designs employed in a couple datacenters. I've seen product sheets for quarter and sixth rack (with the sixth introduced in this thread).
To me, those seem like ideal cabinets to put in MMRs, which traditionally have full cabinets. By count of networks, there are far more networks that employ routers smaller than say 4U than there are ones that use larger than say 12U. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Chris Woodfield" <rek...@semihuman.com> To: "Mike Hammett" <na...@ics-il.net> Cc: "Bevan Slattery" <be...@slattery.net.au>, "North American Network Operators' Group" <nanog@nanog.org> Sent: Saturday, February 13, 2016 6:33:04 PM Subject: Re: Shared cabinet "security" I've seen colos sell half-racks where both the top and bottoms of the racks have their own cabinet doors.
