Access to the cabinet won't be a problem, as it will be directly through the data center, and it would be a locking half cabinet, where each half has its own locking door. I'm looking more for what-if situations and things that could pop up down the road, rather than what I'll notice immediately.
Originally posted by bqinternet Other than the obvious price difference, is there any other advantage to renting a full cabinet at a data center when compared to a locking half cabinet, as far as cooling issues are concerned?
I would certainly recommend the top half of the cabinet. Normally, a cabinet has fans to push the hot air upward from the cabinet's ceiling. Also, you may want to check the power provided by the datacenter since servers today can absorb more current. If you can get 20amps, that would be wonderful.

Another con to the bottom half is having to deal with the cables from the top half.
The only negative I could think of, is if you were at the DC at the same time working on your equipment as the person with the other half of the cabinet. It could get crowded, but what are the odds of this happening? and is it worth buying the extra space? I do not think so.

Most large colo's only discount half racks by about 30% over a full rack, so the price difference may not be that large depending on how many amps are included with the half or full.
Gotcha's could include anything that the other client sharing your cabinet could contribute to. Would you want to share a rack with someone running a full 20 or so 1U Dual Xeon's with full power loads pushing all that heat up into your half of the rack? I think not.
I don't think most people give it much consideration, there seems to be too much thought into optimizing rack space at any cost, but your primary issues are power and heat management. Having that full 42U dedicated to your equipment certainly helps.
Originally posted by PSFServers Well, you see, I think the cabinet manufacturers have done it all worng, I say! You get a 47U cabinet, don't you think you should be able to stick 47 1 U servers in there instead of skipping slots?
Why don't they just make the enclosure about 4 inches deeper so you could zip-tie some big Wal-mart $9.98 box fans on the door and really get the air moving.
I think I'll get some sheet metal, fire up the welder and build the "Hurricane".
Was thinking that a few days ago.. got a big fan which fills half a rack.. we got a big space in the back of our half rack because we didnt get the long 2u cases.. change the fans the other way round and put thiss 240 v fan in there and im sorted.. i think.. Would this acctually help though only an idea :p
