Right, but that doesn't limit one's ability (intentional or not) to pull out the wrong power cord or smack someone's loosely ran cables, etc. We're sorting out some standards now and I think it'll largely involve color coding, wire looms, horizontal cable management and a "cabinet practices" document defining standards for use in the cabinet. This is meant to protect customers from themselves and each other.
IE: Someone is removing a power cable and the pull the wrong one out of the PDU. Maybe they pull the right one out of the PDU, but it's wrapped around someone else's power cable and theirs gets pulled out along the way. Stuff like that. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Greg Sowell" <g...@gregsowell.com> To: "Mike Hammett" <na...@ics-il.net> Cc: "NANOG list" <nanog@nanog.org> Sent: Saturday, February 13, 2016 10:16:17 AM Subject: Re: Shared cabinet "security" Mike, I've seen people use shelves to segregate cabinets. I've seen some that screw from both sides and eat very little space.

Most networks aren't going to need more than a handful of U in a datacenter, but the more significant the datacenter, the less likely they are to provide partial cabinets... which makes no sense. Sure, some networks need large chassis routers chewing up 10U - 20U, but there are far more networks that need routers that take up 1U, 2U, something like that. For many networks, the sheer cost of the space in the datacenter doubles their overall cost per megabit. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Bevan Slattery" < be...@slattery.net.au > To: "Mike Hammett" < na...@ics-il.net > Cc: "North American Network Operators' Group" < nanog@nanog.org > Sent: Saturday, February 13, 2016 2:36:34 AM Subject: Re: Shared cabinet "security" Sorry.

Able to build in a separate and secure cable path for interconnects to the meet-me-room and connection to power supplies. Can be done and I think there are now rack suppliers that do this as standard. Been out of DC space for a few years now.
