An amazing read, thank you!

RE: Datacenter powering

[James Braunegg]

Dear Graham



Happy to provide information as I love datacentre infrastructure along with the 
fact our design was awarded Uptime Institute Tier IV Accreditation.



At a very high level we have 3 switch rooms (R1, R2 and R3)



Switch Room 1

Has two ATS (one primary one backup)  both ATS are feed directly from street 
power

Room 1 ATS A is connected to Generator A (Active)

Room 1 ATS B is connected to Generator B (Standby)



Downstream from Room 1 ATS A and B is distribution board R1-A, R1-B and R1-C

Switch board R1-A and R1-B is IT load, switch board R1-C is mechanical load

Both switch boards R1-A and R1-B have their own dedicated UPS and provider 
power to all racks (Feeds R1-UPS-A and R1-UPS-B)





Switch Room 2

Has two ATS (one primary one backup)  both ATS are feed directly from street 
power

Room 2 ATS A is connected to Generator A (Standby)

Room 2 ATS B is connected to Generator B (Active)



Downstream from Room 2 ATS A and B is distribution board R2-A, R2-B and R2-C

Switch board R2-A and R2-B is IT load, switch board R2-C is mechanical load

Both switch boards R2-A and R2-B have their own dedicated UPS and provider 
power to all racks (Feeds R2-UPS-A and R2-UPS-B)



How it all works

The end result is each rack within the facility has four 32 amp PDU rails, 
where each rail is feed from an independent UPS via 4 independent and isolated 
cable paths.



Each PDU rail within each rack has 24 x c13 sockets where each C13 socket is 
metered, monitored (Web, API, Email and SNMP) & alarmed (Min / Max  on each 
socket) (amps, kwh, PF etc) so we know the exact power consumption on each 
socket on each PDU in each rack.



Each dual corded devices within any rack the device must be connected to both 
Room 1 and Room 2 to provide correct power redundancy.

For single corded devices we have a 1RU STS devices in each rack which takes 
protected power from both Room 1 and Room 2 to provide STS protected power to 
single corded devices if required.





Switch Room 3

Switch Room 3 has two ATS (one primary one backup)  both ATS are feed directly 
from street power

Room 3 ATS A is connected to Generator C (Active)

Room 3 ATS B is connected to Generator C (Standby)



Switch room 3 provides a third independent source of protected power to the 
datacentre if required for additional mission critical applications, and fully 
independent power to support backup cooling infrastructure.



If you want to know more we have some info graphics and more information on our 
website here - https://www.micron21.com/about-us/the-micron21-datacentre/



As for what would I change in our design, at this stage nothing... Planning and 
designing a datacentre infrastructure which meets your high availability 
requirements day one is key before you build.



Hope this helps provide you some information to review.



If you have any more questions please just ask.


Kindest Regards,

James Braunegg

Anybody out there willing to provide a brief description of the power 
configuration in your datacenter today and further comment on if there are ways 
you would reconfigure it given the chance?



To provide context, I am asking from the standpoint of a datacenter operated 
for your own use, not part of a co-location type environment. Total power draw 
in my situation is ~100kW.

We have our exchange in these facilities.  Some info on their web-site about 
power.
