HP POD 40c and 20c
The POD 40c is 40 feet (12 m) long with 1100U of rack capacity and twenty-two 50U 19-inch
(482 mm) deep racks (Figure 12). It offers capacity equivalent to a 5,000 ft
2
(464 m
2
) traditional
data center. It provides up to 600 kW of non-redundant capacity or 380 kW of fully redundant
capacity. Facilities personnel can connect it directly into 480 V utility power and the chilled water
system.
The POD 20c is 20 feet (6 m) long with 500U of rack capacity in ten 50U 19-inch (482 mm) deep
racks. It offers capacity equivalent to a 2,000 ft
2
(186 m
2
) traditional data center. It provides up to
290 kW of non-redundant power capacity or 145 kW of fully redundant capacity. Facilities
personnel can connect it directly into 480 V utility power and the chilled water system.
Figure 12: The design of the HP POD 40c
We engineered the HP POD 40c and 20c for the highest efficiency of a water-cooled data center
with standard air-cooled IT. The PODs minimize power losses by decreasing the number of power
conversions. High-voltage 3-phase AC (400-480v AC depending upon location) is used as the input
to the POD and then delivered directly to the racks as separate single-phase feeds for distribution to
the servers. Highly efficient airflow and separate hot and cold aisles minimizes mixing and
recirculation, and it maximizes cooling efficiency with a cold aisle that can be run up to 90°F (32°C).
