DIY PDU Power Ramp

Okay so finding a data center isn’t the most difficult thing. You can just go to sites like https://baxtel.com/map or https://www.megaport.com/megaport-enabled-locations/ that have great global maps.

Then when it’s time to move in you could be faced with challenging ramp options. Power might not be available right off, or it might make financial sense to move in over time while as your migrating equipment. Rpdu’s come in block options of basically 5, 8.5, and 17kW. In many ways 17kW has become the new standard to support high powered servers and chips. It can be difficult in this form factor to not blow through a lot of distributed power in just a few cabinets.

A potential solution that we’ve found is leveraging extra deep 1200mm cabs and planning for a quad pdu setup. This way you can populate more cabinets broadly and dense them up over time. This is also a way to hedge your bets if it turns out that power requirements actually need to be tweaked.

In this case you could have options like this.

L21-30’s at 8.5kW starting – adding L6-30’s at 5kW for a total of 13.5kW. L21-30’s at 8.5kW starting – adding a 2nd set of L21-30’s 17kW (new standard) L21-30’s at 8.5kW starting – adding 460C9W’s at 17kW for 25.5kW (high density).

You get the picture. Rightsizing is the ultimate goal to not need to over commit to the facility while still having ample power. I know what you’re thinking, that doubles my rpdu budget, but that can be made up in a couple months of power savings. Whenever you walk through a datahall and see rack after rack lightly populated you’ll know their options were constrained and as much as they tried they not only got to buy another set of rpdu’s but another cab too.

It’s also a good idea to look into universal pdu options if you’re worried about managing rpdu plug types in a complex deployment.
