Backup Battery HPE P02377-B21

The HPE Smart Storage Hybrid Capacitor (Backup Battery HPE P02377-B21) is a battery-free backup power solution designed to protect cached data on HPE Gen10 servers. It provides centralized backup power for multiple Smart Array controllers by combining NAND flash memory on HPE Smart Array Performance Class controllers with the hybrid capacitor module to preserve cached data in the event of an unexpected server power loss. The module keeps critical parts of the controller active long enough to copy data from the onboard cache to non-volatile flash memory. Physical dimensions are approximately 254 mm (width) × 222.5 mm (depth) × 57.9 mm (height); product colour: black; weight: 0.34 kg.

Advantages

The HPE Smart Hybrid Capacitor eliminates the need for lithium-ion batteries, removing associated replacement costs and environmental disposal concerns while delivering a rapid, maintenance-free method to secure cached data. As a centralized backup power source, it supports multiple controllers and integrates with HPE Smart Array Performance Class controllers to enable fast transfer of cache contents to NAND flash during power events. Its compact form factor and light weight simplify installation in server environments compatible with HP Smart Array P824i-p MR Gen10 and P816i-a SR G10 LH controllers.

Suitable for

• HPE Gen10 servers using Smart Array Performance Class controllers
• Systems with HP Smart Array P824i-p MR Gen10 controllers
• Systems with HP Smart Array P816i-a SR G10 LH controllers
• Data centers seeking battery-free cache protection

How to use

Install the hybrid capacitor module according to the server and controller installation procedures provided by HPE. Connect the module to the compatible Smart Array controller bay or central backup power connector as specified in your server documentation. Once installed and recognized by the controller firmware, the module operates automatically: when power loss is detected it supplies the controller long enough to transfer cached data to NAND flash memory. No regular charging or battery replacement is required.

Recommendations

Use this HPE Smart Hybrid Capacitor in systems specified by HPE for Gen10 servers and supported Smart Array controllers (for example P824i-p MR Gen10 and P816i-a SR G10 LH). Follow HPE installation guides and firmware requirements, ensure controller firmware is up to date, and verify compatibility with your server model before deployment.
