Energy pack options
Hewlett Packard Enterprise offers two centralized backup power source options to back up write cache content on P-class Smart Array controllers in case of an unplanned server power outage.
HPE Smart Storage Hybrid Capacitor
IMPORTANT:The HPE Smart Storage Hybrid Capacitor is only supported on Gen10 and later servers that support the 96W HPE Smart Storage Battery.
One energy pack option can support multiple devices. An energy pack option is required for P-class Smart Array controllers. Once installed, the status of the energy pack displays in HPE iLO. For more information, see the HPE iLO user guide on the Hewlett Packard Enterprise website (http://www.hpe.com/support/ilo-docs).
