Table 56. Power consumption and environmental information for the DS8000 series - Models 941 and
94E (continued)
Notes:
1. The values represent data that was obtained from typically systems configured as follows:
v
Base models that contain eight disk drive sets (128 disk drives) and fibre-channel adapters.
v
Expansion models that contain sixteen disk drive sets (256 disk drives) and fibre-channel adapters.
2. LWAd is the statistical upper-limit A-weighted sound power level, expressed in bels, declared in conformance
with ISO 9296. The values correspond to DS8000 models that contain 128 disk drives. The values represent data
obtained during preliminary testing. Bels relate to decibels (dB) as follows:
1 B = 10 dB . The ratings are rounded
to the nearest 0.1 B. Measurements are in conformance with ISO 7779.
3.
All models and configurations that are used in single-phase mode must not exceed 8 kVA.

1. The values represent data that was obtained from typically systems configured as follows:
v Base models that contain 15 disk drive sets (16 drives per disk drive set, 15 disk drive sets x 16 = 240 disk
drives) and fibre-channel adapters.
v
Expansion models that contain 21 disk drive sets per enclosure (21 disk drive sets x 16 = 336 disk drives) and
fibre-channel adapters.
