When building an MDS lab one of the things to keep in mind is that these units require quite a bit of power and they generate quite a bit of heat. Here are some rough figures to go by that I have used in building my lab. My lab uses 3 dedicated 20A circuits. However, since I am using APC power units that are only rated at 15A, I have to keep a 15A budget per circuit. APC (and other manufacturers) do make IP ready PDU’s which can goto 20A or above.
|Cisco MDS 9216A||5|
|HP DL360G3 Server||1.5|
|JMR Fortra 6 Drive JBOD||1.5|
|Xyratex RS-1600-FC2 JBOD||2.5|
|Sun A5200 JBOD||2.5|
|EMC DS-24M2 Switch||.5|
|Brocade Silkworm 2400||.5|
I hope this gives you a basic idea of how many Amps to budget for your equipment. On all equipment I am only plugging in single power supplies.
