HPE 786710-B21

Overview

The HPE 786710-B21 is a battery holder designed specifically for the RAID adapter in the HPE ML150 Gen9 server. Its main function is to provide backup power to the RAID controller, ensuring that write-cache data is preserved during power interruptions. This protection is crucial for maintaining data integrity in environments running virtual machines, file shares, or transactional databases where uncommitted writes must not be lost.

By securely holding the backup battery, this component allows the RAID adapter to either flush cached data safely or maintain it until the server can shut down properly. The design fits seamlessly into the ML150 Gen9 chassis without requiring any modifications, maintaining proper airflow and withstanding the heat and vibration typical of server operation.

Key features

• Provides reliable backup power to the RAID adapter to protect cached data during outages
• Compact bracket that aligns perfectly with existing mounting points in the ML150 Gen9 chassis
• Ensures data integrity by allowing safe flushing or retention of write-cache data
• Durable construction designed to tolerate server heat and vibration for continuous operation
• Easy installation that integrates smoothly into routine maintenance or upgrades
• Supports critical workloads by reducing recovery time after unexpected power failures

Key specs

• Compatibility: HPE ML150 Gen9 server
• Function: Battery holder for RAID adapter backup power
• Mounting: Fits existing chassis mounting points without modification
• Build: Sturdy design to withstand heat and vibration in server environments

Installation and setup

Installation of the battery holder is straightforward and requires no chassis modifications. It aligns with pre-existing mounting points inside the ML150 Gen9 server, allowing quick and secure attachment. Its compact size ensures that airflow within the server remains unobstructed, which helps maintain optimal cooling performance.

This ease of installation makes it a practical choice for IT teams performing scheduled upgrades or drive replacements, minimizing downtime and complexity.

Ideal uses and environments

This battery holder is well suited to branch offices using a single ML150 Gen9 tower or data centers deploying multiple units. It adds an essential layer of data protection for environments where preserving cached write data is critical, such as virtualized servers, file sharing systems, and transactional database applications. Teams that prioritize data integrity and quick recovery after power interruptions will find this component valuable.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
