E UPS and Data Center Power Configurations
This appendix provides examples of UPS and data center power configurations, and:
•
Specifies the UPS configurations supported on the NonStop system including the
recommended UPS configuration for when the disk drive write cache is enabled.
•
Identifies the non-supported UPS configurations that should not be used with the NonStop
system when the disk drive write cache is enabled.
•
Explains why some configurations are not supported.
•
Informs you of what you must do to prevent data loss.
NOTE:
All example UPS configuration illustrations in this appendix show NonStop BladeSystem
hardware, but these configurations are supported on all NonStop platforms and can be used with
single-phase and three-phase UPS.
IMPORTANT:
You must change the ride-through time for a Hewlett Packard
Enterprise-supported UPS from the manufacturing default setting to an appropriate value for
your system. During installation of an NS2100 system or HPE UPS, your service provider can
refer to the "Setting the Ride-Through Time and Configuring for Maximized Runtime" procedure
in the
NonStop NS2100 Hardware Installation Manual
for these instructions.
