The differences between a tier 3 and tier 4 data centre

If you're hosting at a tier 3 data centre, what need would you have for moving over to tier 4? Eddy Conway, Head of Infrastructure, explains the significant differences that shows why our tier 4 design data centre delivers an impressive advantage.

What are the differences between a tier III and a tier 4 data centre? Our Head Of Infrastructure, Eddy Conway, has the answers.

Today I'm here to talk about and give a brief description on the differences between tier 3 and tier 4 data centres and why the resiliency they require is something that we can provide.

In a normal data centre, you have your lovely server, the thing that drives a business, earns you money, keeps you in a job...

You would have your power distribution come off the grid to feed down, to the server. Of course to make this much better and more resilient and the feed because of power cuts, you would think 'what could we do to that?'. We could add in some lovely UPSs - uninterruptible power supplies. Which are basically batteries. But as we all know, batteries can run out, so in the event of a long power cut, they would fail, and your system would go down, so what can you do to stop that?

Next step, generators. Here we have generator #1. Genny #1!

And for resiliency, we'd have to have... Genny #2!

So now you have all your power coming u into your switches and your dials, that feed all your equipment. And you think, 'what could be better than that?' Everything's secure. We have batteries which switch over to generators, we've two generators, brilliant, fantastic. So, this is how you can improve it.

And at the Blue Chip data centre, we have not one, but two distribution units. Here are switches.

And, like on the other one, we now have Genny #3... and... slightly fatter!.. Genny #4! Complimenting the UPSs. My concentration is unbelievable. It's now free then to your equipment that runs your business. I feel it's a lot more safer.

So in Blue Chip, we have gone from tier 3, which is this one on this side, to tier 4, on this side so that - all that is required to protect your business...

I gave you the best resiliency you can get. But is it? At Blue Chip we have gone even further than this, because we have incorporated switch gear, but even when you lose anything on this side, we can actually feed, either way, from the other side, to keep your resiliency at all times.

Just a little recap. What we have in red, is N plus one! And then we bring these UPSs Resilient generators! What we have at Blue Chip's own data centre, is 2 N plus 1. Meaning there is no single point critical piece of equipment that can take our data centre down. So in this extremely resilient data centre, we also have utilised communication. Dual communication, with the outside world completely independent of each other.

On our logos, you'll notice that we actually have our 'leaf'. [I'm] not very good at leaves! Why do we use a leaf? Our leaf is there because we run a data centre with a PUE of 1.1. It is very green, very ecological and it's very successful.

What you have here, is a reliable, serviceable, upgradable environment to run your systems in.
