Question on Power for c-Class Blades - Anyone know off-hand?

[nvongsy]

Product: c-Class blades, BL460c We’ve been checking with couple of datacenters and they all said that maximum power of 20 Amps @ 208V can be provided for each cabinet. Then how can it be possible to stack 3 to 4 enclosures into one cabinet when each enclosure requires two 30 Amps circuits?

We're going with dual 60Amp 3 phase circuits to our blade racks. That should cover up to 4 enclosures assuming our cooling will keep up.

We usually find that most data centers can only cool a max of 3-c7000 enclosures (48-Blades) in one rack. We do often use Two three-phase monitored PDU's (60A) with the IEC 309 plug for the rack when using Three c7000 Enclosures.

It depends on the datacentre, I know some places that won't let you go over 2Kw/rack and there's that new place in Vegas that'll clear 80Kw/rack if you need it. It all depends on the design of the place, you generally find that centre managers/designers don't like to spend money up-front so under-spec their power/area ratio. Phil.
