HPE P02377-B21 – Smart Storage Hybrid Capacitor with 145mm Cable Kit

Overview

The HPE P02377-B21 is a Smart Storage Hybrid Capacitor designed to provide cache backup support for supported HPE Smart Array storage controllers. It is used to protect in-flight write cache data during sudden power interruption, ensuring data integrity in RAID-based storage systems.

It uses a hybrid capacitor-based energy storage mechanism instead of a traditional battery design. This allows rapid energy discharge to safely flush cached data to persistent storage in the event of power loss.

The unit is supplied as a capacitor module with an integrated 145mm cable kit for internal server installation. It is designed to be mounted inside supported HPE ProLiant server platforms as part of the storage protection subsystem.

It is typically used in enterprise environments where RAID write-back caching is enabled and data protection during power failure is critical.

Typical Deployment Scenarios

Used in RAID-enabled enterprise servers where Smart Array controllers rely on write-back caching. Common in virtualization hosts, database systems, and enterprise workloads requiring fast storage performance with cache protection. Also used in data center environments where power-loss protection is required for cached storage operations.

Technical Specifications

Compatibility / Ecosystem

Designed for use with supported HPE Smart Array storage controllers in enterprise server environments. Integrates into HPE Smart Storage ecosystems where hybrid capacitor-based cache protection is required.
