Appendix D. SAS expansion enclosure requirements
Before you install a Storwize V5100 2077/2078-12F , 2077/2078-24F , 2077-92F, 2077-A9F or
2078-92F, 2078-A9F 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 27 on page 101 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.
