Hi,
I'm in a bit a of a bind, or I think that I am, and hoping that someone here can tell me if I am or not :(....
The situation is that we got a new Sun server (a V880) in for a fairly short evaluation period. This was suppose to go into a new area, and there was some mis-communication between Sun and another guy at work, and then he left, and I'm stuck with getting things going now :(.
What happened was that he had asked Sun what kind of power was needed awhile, and they told him that their rack/power distribution (PDS) required 2 240V circuits @ 30 Amps each, with L60-30 receptacles/outlets, so that's what he went and got provisioned in the room.
Unfortunately, it turns out that Sun isn't able to provide their rack or their PDS, so I'm now stuck trying to figure out how to power the server, at least temporarily.
We're trying, but having a bit of a problem getting a proper PDU quickly, and meanwhile the Sun hardware arrived today. We'll be unpacking and inventorying tomorrow, but there's already a bit of pressure on me to try to power them up.
It turns out that besides the L6-30 outlets that we have, which we can't use until we get a PDU, we have some standard 120VAC outlets around the room. According to our electrical contractor, all the 120VAC outlets in that one room are wired back to a single 20Amp breaker.
I've been reviewing the following article on Sun's website:
We have only 6 drives, so it looks like the system power draw would be about 1755 Watts, or ~14.6 Amps @ 120V. This would be total, for the 2 power supplies in a single 880 (the 880 can have up to 3 power supplies, but needs at least 2 minimum to operate), so each power supply would be drawing ~8 Amps @ 120V from a single 120V outlet, I think.
So, if I'm calculating correctly, and if the breaker for the room is really 20 Amps, then will I be ok plugging the two power supplies from ONE 880 into two of the 120V outlets, and be able to power the 880?
I'm assuming that if the breaker is really 20Amps, that all the wires to the outlets will be rated for 20 Amps? Is this correct?
Also, what is the "normal" power/amp rating for a 120V outlet (this is in an office setting)?
I *KNOW* that this will be "cutting it close", and I've told people at work that I want to wait for the PDUs to come in, but I'd really like to get some feedback on this, as soon as possible. I don't want to do anything unsafe!!
My apologies for this, but I hope that someone who has more experience can respond!!
Thanks, Jim
