IBM Elastic Storage System 5000 Series User Manual

• The rack design must support the total weight of the installed enclosures and incorporate stabilizing
features suitable to prevent the rack from tipping or being pushed over during installation or normal
use.
• The rack must not exceed the maximum enclosure operating ambient temperature of 32-degrees C,
using any optical cable or discrete optical transceiver, including all Ethernet (100 Gb) cables and
InniBand (100Gb EDR). However, when you are using the copper cable, the maximum ambient
operating temperature can be 35-degrees C, including all Ethernet and InniBand cables.
In particular, the rack front and rear doors must be at least 60% perforated to enable sufcient airflow
through the enclosure. If there is less airflow, additional mechanisms are required to cool the
enclosure. An appropriate IBM rack conguration would be the 7014-T42 IBM Rack Model T42, with
standard rear door and feature code 6069 Front Door For 2.0 Meter Rack (High Perforation).
• The rack must have a safe electrical distribution system. It must provide overcurrent protection for the
enclosure and must not be overloaded by the total number of enclosures installed. The electrical power
consumption rating that is shown on the nameplate should be observed.
• The electrical distribution system must provide a reliable ground for each enclosure in the rack.
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 6 on page 27
lists the rating of each power
supply unit (PSU) by enclosure.
The power that is used by the system depends on various factors, including the number of enclosures and
drives in the system and the ambient temperature.
