The HPE Smart Storage Hybrid Capacitor is a battery-free technology for power storage that provides data protection for cached data while eliminating costs and environmental impact of lithium-ion batteries.
For those running HPE Gen10 servers, the HPE Smart Hybrid Capacitor is a centralized backup power source supporting multiple controllers where the NAND flash memory on HPE Smart Array Performance Class controllers and the HPE Smart Hybrid Capacitor work together to save cached data in the event of unplanned server power loss.
Overview
When the hybrid capacitor module detects power loss it keeps critical parts of the controller active long enough to allow data to be copied from the onboard controller cache to the flash memory.
Please note, although the hybrid capacitor module is mechanically compatible with the 96W Smart Storage Battery (P01366-B21 and P01367-B21), the module cannot be used in combination with the Smart Storage Battery. In most cases, only a single Smart Storage Battery or a single Smart Hybrid Capacitor can be used per system. Please check your server platform QuickSpecs for details.

Standard Features
Ideal for
The HPE Smart Storage Hybrid Capacitor is ideal for:
- − Environments with higher operating temperatures.
- − Customers who have a “no battery“ requirement or applications/environments such as ASHRAE, NEBs, Telco and certain data center or system environments where elevated internal system temperatures are experienced.
Key Features
- − High reliability, even in higher temperature environments.
- − No batteries, not a Class 9 Dangerous Good product (no hazardous material disposal, no battery shipping requirements).
- − A single module supports up to three (3) Smart Array Controllers.
- − Charges to full capacity in ~3 minutes after discharge.
- − Capable of operating in higher temperatures with no impact to service life.
The HPE Smart Storage Hybrid Capacitor is used to provide backup power to the HPE storage array controller in the event of power loss. The hybrid capacitor module starts up automatically and charges the capacitors when charge is required. In the event of a power loss, the capacitor pack will switch to discharge mode and supply energy to write the cache contents to NAND memory.
For more information on best practices see HPE Smart Array Controller User Guide.
Notes:
− The HPE Smart Storage Hybrid Capacitor is only supported on Gen10 servers or newer. Before installing the hybrid capacitor module, verify that the system BIOS meets the minimum firmware requirements to support the capacitor pack.
− Not for use with Server that use NVDIMMs.
− For more information on updating firmware, see the Intelligent Provisioning User Guide on the Hewlett Packard Enterprise website http://www.hpe.com/info/intelligentprovisioning/docs.
