Power Requirements; Environmental Requirements - IBM TotalStorage DS6000 Series Redbooks

Use the following steps to calculate the required space for your storage units:
1. Determine the dimensions of each model configuration in your storage units.
2. Determine the total space that is needed for the storage units by planning where you will
place each storage unit in the rack.
3. Verify that the planned space and layout also meets the service clearance requirements
for each unit.

7.2.2 Power requirements

We describe here the input voltage requirements for the DS6000 series.
Input voltage requirements
The DS6000 series has built-in redundant, auto-sensing, auto-ranging power supplies. The
power supplies are designed for operation in a voltage range of 90-257 V AC, 50-60 Hz.
Table 7-4 lists the input voltages and frequencies that the DS6000 series power line cords
support. The values apply to both of the primary line cords to any storage or expansion
enclosure in a DS6000 series. The DS6000 series power inputs are single phase.

Input frequencies
Two independent power outlets for the two DS6000 power line cords are needed by each
base model and expansion model.
Important: To eliminate a single point of failure, the outlets must be independent. This
means that each outlet must use a separate power source and each power source must
have its own wall circuit breaker.

7.2.3 Environmental requirements

To properly maintain your DS6000 storage unit, you must install your storage unit in a location
that meets the operating environment requirements.
Table 7-5 describes the environment operating requirements for the DS6000 series.
