Power from utility and share of power to servers
Monday Dec 11, 2006
I've seen a variety of figures, anyone have completely vetted data?
Here is what I've been able to find. Note the first table slices and dices that data differently than the second two tables:
| Stage | Watts |
|---|---|
| Power our of utility | 1000 |
| Power lost in distribution | 29 |
| Power for HVAC | 169 |
| Power for distribution | 224 |
| Power to servers | 578 |
Another source shows the following for a datacenter that has lots of power for infrastructure:
| Use | Watts |
|---|---|
| Power into Datacenter | 1000 |
| Power lost UPS | 90 |
| Power lost in HVAC (air) | 160 |
| Power lost in chiller & pumps | 340 |
| Lighting | 80 |
| Power to servers | 330 |
Another source shows the following for a datacenter that that uses little power for infrastructure:
| Use | Watts |
|---|---|
| Power into Datacenter | 1000 |
| Power lost UPS | 50 |
| Power lost in HVAC (air) | 50 |
| Power lost in chiller & pumps | 160 |
| Lighting | 10 |
| Power to servers | 730 |
