RACK59 Releases Pertinent Information on Diverse Power in Data Centers

A company wants diverse power to the substation and to the distribution panel with two generator that are supplying diverse UPSs that are ultimately supplying diverse power to the PDUs with a company’s rack.

The “A” side UPS goes to a company’s “A” side power distribution unit or PDU and the “B” side UPS goes to a company’s “B” side PDU. With this kind of redundancy, a company’s rack should never loose power.

Diverse Power in a Data Center

There are several different layers that contribute to keeping a company’s rack diversely powered at all times. Every layer is just as important as the one before. On of the biggest contributors to power in a data center is the substation.

The substation actually feeds power to the data center from the utility company. It is important that a company knows where it is located. A few questions to ask are if the substation is onsite and dedicated to the facility or is it miles away? A company wants to know this in case there is a natural disaster so that they know if their substation, that is feeding power to their rack, is affected. The other thing that a company wants to know about the substation is how it is fed. The preferred way is to have diverse power generating sources going into the substation.

Next, a company wants to see that, from the substation, there are diverse power entries into the building into diverse generator distribution panels. The more diversity the data center has the better. From there a company should look for “A” side and “B” side diesel generators. The best thing about having “A” side and “B” side generators is that it allows any potion of the chain to fail without a company’s rack loosing power in anyway.

A data center should have even more protection than the generators. If there is for any reason a utility outage, the generators will power on. While the generators are powering on the uninterrupted power supplies or UPSs would turn on to hold the load. As soon as the generators are up and running and supplying power, the UPSs turn back off and go back to being charged.

From the UPSs, we get to a company’s rack. The “A” side UPS goes to a company’s “A” side power distribution unit or PDU and the “B” side UPS goes to a company’s “B” side PDU. With this kind of redundancy, a company’s rack should never loose power.

To recap, a company wants diverse power to the substation and to the distribution panel with two generator that are supplying diverse UPSs that are ultimately supplying diverse power to the PDUs with a company’s rack. A company wants to make sure that their data center has all of these levels of power to ensure that their more valuable asset is always accessible.
