If you are running a server room in your place of business, you are probably using some form of PDU to connect all of your servers and peripheral equipment to a centralized source of power. This is a fairly typical set up as it allows you to take full control of your entire power distribution setup; the only thing you have left to worry about is the event of a power loss.
Adding a UPS to Your PDU Can Keep Your System Running Just Long Enough
While the average UPS can only keep a system up and running for a very short period of time, you should still connect one to your PDU. By doing this, you will be able to keep your servers up just long enough for everyone using them to be able to save their work instead of losing it in the event of a complete power outage.
When you are putting together your server racks, you need to be very conscious of the amount of power that the finished system is going to draw. If you find that the number of amps that all of the combined units are going to require to function at maximum capacity are too high for a standard power strip, you may find that you have to install a PDU in its place.
A PDU Can Handle Heavier Current Loads
One problem that you can end up facing with a simple power strip that cannot handle the loads is that this lack of power can prevent your servers from getting the power they need to run at full capacity. When this happens you could be faced with servers that either slow down to a crawl or overheat, which could lead to a fire. With a PDU you can choose the one that is most suited to handling the maximum load your servers are likely to place on it and leave room to spare, so that you never have to worry about these risks.
