#3 Datacenter tags

Alper Üzmezler Wed 20 Apr 2011

I would like to start datacenter tags. This would simplify DataCenter PUE and other analysis functionalities to be built in applications. What does everyone else thinks on this topic?

Sounds great, just start posting/brainstorming ideas and we'll see where it leads

dataCenter - Data center name tag

dataCenterRef - Any equipment that references the data center like pdu, generator, crac units

pdu - Power distribution unit

pduRef - This is the reference tag for the power distribution unit. Panel boards references to the pdu.

pduNum - This tag would be added power distribution unit as a character or a numeric define power distribution unit.

panelBoard - This tag would need a string A B C D E and would referenced to pdu.

panelBoardNum This tag would be added to panel board as a character or a numeric define panel board number on a pdu.

panelBoardRef - This is the reference tag for the breakers.

breaker - This is the breaker tag.

breakerRef - This would be referenced to the panelBoard

breakerNum - Assigned integer to the breaker tag such as breaker-1, breaker-2 The goal would be to find the breaker location by PDU-1 PB-A BR-40

phase - This would be assigned as a tag to the breaker as the phases it would contain.

tileLocation - This is a string tag where it defines the location of the unit such as A1, F5. This would apply to pdu, crac unit, electrical switch or a computer. We need to standardize the tags but I am not an expert on this. I worked on 4-5 data center projects. Inputs are welcome for standards.

rackLocation - This is a string tag where the specific computer equipment is located.

rackLocationRef - This would be described where the server type is located.

cracUnit - The cooling device for the data center. We can extend this from an ahu just like the rtu. They work quite the same inputs are welcome.

cracUnitRef - Anything that references the crac unit such as cool, heat stages.

Please comment on this as what you think would wrong and should be changed to a different tag.

tempSensor - Temp sensor located various locations of the data center. tileLocation string would be referenced to create heat map for the datacenter.

generator Tag for electricity generator for the data center or any other system.

@Alper,

Great start, I think we need to loop in some more people who really understand data centers and then we move this towards some formal proposals.

One thing that strikes me is that many of these tags probably relate to the electrical system which might make sense to break out into a separate electrical system model and shared with data centers. For example breakers and which breaker a piece of equipment is on makes sense across any piece of electrical equipment. So that will continue to be a challenge: how we organize our systems.

@Alper

How did your data center work out?

I'm starting to tag up mine now.

I am using your tags as a guide.

We've got minor differences in some terminology: your panelBoards are an integral part of my PDU.

I am skipping the breakerRef and rackLocation.

Is your tempSensor independent of your CRAC units?

I'll need a generatorRef, utility marker, utilityRef, utilityNum, ups marker, upsRef and upsNum.

@Brian

Data Centers are quite diverse in size and usage.

I agree we need a more robust electrical energy model.

The energy app is relatively flat: siteMeter < submeterOf < elecMeterLoad

Many data centers are many-headed trees. Multi-threaded spiders.

utilityFeed1 > parallelSwitchGear < UPS1 < PDU-1-n < panelBoard_x < rackLoad_y utilityFeed2 > parallelSwitchGear < UPS2 < PDU-2-m < panelBoard_x < rackLoad_y generator1 > parallelSwitchGear < UPS3 < PDU-3-o < panelBoard_x < rackLoad_y generaror2 > parallelSwitchGear < UPS4 < PDU-4-p < panelBoard_x < rackLoad_y

Many data center electrical systems have both the primary and alternate electrical paths, multi-threaded...

The data center load manager is interested in the aggregate load at each level.

What is the overall load in case a utility feed goes down?

What is the overall load of each UPS in case it needs to be taken down for maintenance? What's trend? When will I be at the capacity limit?

What is the overall load of each PDU in case it needs to be taken down for maintenance?

Which PDU can I add more load to? And therefore which UPS, and utility.

We could use some stellar visualizations like you've done for HVAC...
