HPE P25903-B21

Overview

The HPE P25903-B21 is a secondary riser kit designed specifically for the DL38X Gen10 Plus server, enabling the addition of two large form factor drives within the existing chassis. This kit provides a practical solution for expanding internal storage capacity without compromising airflow or cable management, making it ideal for environments where data growth and performance are critical.

By integrating this riser, administrators can support workloads that require fast local disk access, such as analytics, virtualization clusters, or file sharing, all while maintaining a slim and efficient server layout.

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.
