IBM Storwize V7000 - Page 181

The power and thermal measurements that are shown in Table 23 on page 151 were obtained in the
specic operating environment and under the conditions described. These measurements are presented
as an illustration; measurements that are obtained in other operating environments might vary. Conduct
your own testing to determine specic measurements for your environment.

Each Storwize V7000 enclosure contains two PSUs for redundancy. The total power consumption values
represent the total power that is drawn by both PSUs.
Environmental requirements
System airflow is from the front to the rear of each enclosure:
• Airflow passes between drive carriers and through each enclosure.
• Airflow for the upper 4U of the 5U enclosure enters the front, passes between the disk drives, and exits
through the large fans in the rear of the enclosure.
• Airflow for the lower 1U of the 5U enclosure is driven through the power supplies via 40 mm X 56 mm
fans. Air continues through the chassis cooling the ESMs or controllers and exits the rear of the
enclosure.
• The combined power and cooling module exhausts air from the rear of each canister.
Ensure that your environment falls within the ranges that are shown in Table 24 on page 151
.
