Rack Airflow Requirements
The following requirements must be met to ensure adequate airflow and to prevent damage to the
equipment:
• If the rack includes closing front and rear doors, allow 830 square inches (5,350 sq cm) of hole
evenly distributed from top to bottom to permit adequate airflow (equivalent to the required 64
percent open area for ventilation).
• For side vented components, the clearance between the installed rack component and the side
panels of the rack must be a minimum of 2.75 inches (7 cm).
• Always use blanking panels to fill all empty front panel U-spaces in the rack. This ensures proper
airflow. Using a rack without blanking panels results in improper cooling that can lead to thermal
damage.
Configuration Standards
EVA configurations are designed considering cable length, configuration CG, serviceability and
accessibility, and to allow for easy expansion of the system. If at all possible, it is best to configure
non HP cabinets in a like manner.
Environmental and operating specifications
This section identifies the product environmental and operating specifications.
NOTE:
Further testing is required to update the information in Tables 45-47. Once testing is complete, these
tables will be updated in a future release.
UPS Selection
This section provides information that can be used when selecting a UPS for use with the EVA. The
four HP UPS products listed in
Table 22 are available for use with the EVA and are included in this
comparison. Table 23 identifies the amount of time each UPS can sustain power under varying loads
and with various UPS ERM (Extended Runtime Module) options.
The load imposed on the UPS for different disk enclosure configurations are listed in Table 24 and
Table 25 .
NOTE:
The specified power requirements reflect fully loaded enclosures (14 disks) .
