Appendix D. SAS expansion enclosure requirements
Before you install a Storwize V7000 2076-12F , 2076-24F , or 2076-92F SAS expansion enclosure, your
physical environment must meet certain requirements. This includes verifying that adequate space is
available and that requirements for power and environmental conditions are met.
Power requirements for each power supply (two per enclosure)
Ensure that your environment meets the following power requirements.
To aid in power and cooling requirements planning, Table 32 on page 157 lists the rating of each power
supply unit (PSU) by enclosure.
The power that is used by the system depends on several factors, including the number of enclosures and
drives in the system and the ambient temperature.
