Rack PDU for Cisco UCS

Hi,  We are preparing the data center for our customer for UCS installation. If i have 3 UCS blade chassis, each with 4 power supplies, i will need 12 x 16A circuit. Can anyone recommend the type of rack PDUs that is commonly deployed for UCS?  Thanks Eng Wee

Check out Server Technology and their Smart CDU line of products:  http://www.servertech.com/products/smart-pdus/smart-pdu-cs-12hd

Here is a document covering use with UCS servers:  http://www.servertech.com/uploads/documents/0000/0611/Cisco-Server-Tech-208V-30A-Two-Cisco-UCS-5100-Series-Blade-Server-Chassis-CS-12HD2-L630.pdf

We are installing UCS this week (2x6120, 2x5108, 8xB250) using on of their CS-12HD2-L630 CDU's.

Just a follow up to say that everything is working fine with our Server Technology Smart CDU.

Re: Rack PDU for Cisco UCS

Rod,

Did you follow server tech's document and only use one PDU? Are you concerned about the single point of failure introduced by having a single PDU? If that device fails you would lose both chassis and your fabric interconnects.

I've been considering server technology for a new data center and now with the introduction of UCS to my enviroment I am having to plan to power it. Why did you not choose verticle power strips?

Appreciate your input.

Cheers.

Also, something like this from APC (a few of them), might work: http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=AP7866A

It does 45 amps per phase on a single PDU, with 12 C19 outlets

Also, are you confident you'll need that much power?  Your specs seem pretty high, in my experience.

Re: Rack PDU for Cisco UCS

I think you are not correctly interpreting you power requirements.  You have 3 chassis w/ 4 PS each and are looking to supply twelve 16A circuits.  I put in 2 chassis w/ 4 PS each and it's working fine using 2 x 30A circuits into a Server Technology Smart CDU.
