Server rack recommendations

rackrackmount

I'm putting servers on a rack for the first time, and am thinking a 4-post open frame rack is adequate for my needs. I'm putting in a few HP DL 385's and a few other things. What I'm wondering is if there's reason to be picky about the rack selection. I'm not concerned about heat or size – just installation and fit. Any recommendations or considerations?

Some things I have learned looking after a smallish machine room of 6 cages:

  • I have had good luck with the APC netshelter, 42U unit.

  • Make sure it's long enough to accommodate your rackmount equipment

  • Make sure you have the rails for your equipment - they are often mated to your case

  • Account for space eaten by UPS unit(s), I put mine in the bottom of the rack as they are heavy

  • Take into account power cable lengths; typical server power cables are usually not long enough to reach servers in the top 8 or so of U the rack, you may need to get a power strip to distribute power

  • Make sure there is enough room behind the unit so that you can get in behind to cable, power down and generally fiddle with stuff

  • Make sure there is reasonable ventilation in back as all the heat is going to be concentrated to some degree

  • Most folks don't leave spaces in the rack between units as the only airflow that matters is what can actually be sucked in the front of the rack to cool the parts inside

  • Never rackmount new gear alone. This stuff is heavy and bulky. Have at least an extra set hands to help: no need to lose toes, hands etc or damage equipment especially when racking in the upper portion of the cage. Get a lift unit or scissor table to help if you can

  • Make sure you have the right kind of power plugs at the installation - rackmount equipment doesn't always have the nema office power plugs, especially the 30+ amp rackmount ups gear - no bigger bummer than putting it all together and have no way to power up :(

Hope this helps.
