For every data center business, it’s imperative to ensure the 100% availability of its data center. Perhaps that’s the reason why it’s important to build tier 3 data center as per the tier 3 data center specification. Here’re the few essential steps you need to consider.
In 2016, the cybercrime especially the distributed denial of service (DDoS) attacks – were behind 22% of all the unplanned outages reported. Redundancy and Concurrent maintainability are the two major requirements that a reputable tier 3 data center must facilitate. For all the power and cooling components, it takes at least n+1 redundancy and concurrent maintainability.
Be mindful that the lack of availability of these components shouldn’t be affecting the normal functions of the infrastructure. If you’re wondering about how to upgrade your facility’s power supply infrastructure so that it successfully meets the tier 3 data center specification. So let’s dive in;
Inevitably, the electricity from utility service suppliers is an unreliable source of power especially when you’re dealing with the data center. Consequently, tier 3 Data centre specifications require that one must have diesel generators as a backup. It’s best to have the automatic transfer switch (ATS) that automatically switches over to the backup generator in case the utility power source goes down.
Since many businesses have just a single ATS connecting a backup generator as well as the power source from the utility service provider, the Tier 3 Data centre specifications support 2 ATS connected in parallel ensuring redundancy along with concurrent maintainability.
To have at least 12 hours of gasoline supply as reserves, Tier 3 information centre specifications require the diesel generators. Also, make sure to have two tanks for Redundancy and each with 12 hours of gasoline. To ensure the concurrent maintainability, it’s better to use the two or more fuel pipes for the tanks. You can then maintain the fuel pipes without affecting the gas flow to the generators.
Power Distribution Panel
With the help of UPS, the power distribution panel is responsible for distributing power to the IT load. Additionally, it also distributes power to the non-IT loads. Data centres can achieve the Redundancy and concurrent availability with the help of different power distribution panels for each ATS.
Connecting two ATSs to some panel will demand to bring down equally ATS units during panel maintenance or even replacement. For the Tier 3 Data centre specifications, there are at least two power lines required between each ATS & power distribution panel to ensure redundancy & concurrent maintainability. The same way, every single power distribution panel along with UPS needs to have two or more lines.
When it comes to the UPS Power, it’s used by the UPS from distribution panel and then supplied to the power distribution boxes for both server racks and network infrastructure. For instance, in case the Data center needs 20 KVA UPS, redundancy can be achieved by deploying two 20 KVA UPS.
For redundancy and concurrent maintainability, the Tier 3 data centre specifications require that each UPS be connected to just one distribution box. Consequently, only one power distribution circuit goes down if something goes wrong with the UPS.
In tier 3 data center, every server must have two power distribution boxes to data centre specifications. With dual power source attributes, they can connect to the power distribution boxes. A static switch may be used for devices lacking dual power mode features. This switch takes in supply from both the power distribution boxes giving one output. Just within a few milliseconds and the static switch can transfer from a power distribution box to another in case of failures.
