Table 5-9 shows similar information for full-wide compute nodes with average
powers of 1000 W, 1200 W, and 1400 W. The number of supplies indicated in the
table are theoretical, and might not represent a practical configuration. For
example, although a specific number of supplies might be adequate to power the
indicated configuration under normal operation, it may require the blades to
throttle the power to unrealistic or impossible levels during a fault to keep the
system running.
