At one point I debated fabricating my own and had some constructed by a metalfab, but, for splitting racks, if you're using a standard cabinet: http://www.middleatlantic.com/rackac/security/security.htm http://www.middleatlantic.com/rackac/security/security.htm Several manufacturers sell half-cab cabinets where you have 2 individual locks. Of course, you might need to negotiate with he.net to get them to put that in prior to your start. Raritan makes a power strip that is a little costly, but, allows you to control power by outlet, set triggers, see what the power use is by outlet, interfaces nicely with several stonith profiles. Individual web access by port (if I recall, we don't use that feature) The highest density/power efficient box we've been using is a Supermicro 512-L, X7DVL-3, dual quadcore xeon, 24gb RAM. At load, .9 amps.
