HPE 8SFF Tri Mode 24G U.3 Basic Carrier Backplane Kit

The HPE P26429-B21 is an 8SFF Tri Mode 24G U.3 Basic Carrier Backplane Kit that brings flexible, high-speed storage expansion to ProLiant DL360 Gen10 servers. It installs in place of the existing backplane and opens eight Small Form Factor bays that can be populated as your workload grows.

Each bay connects through a Tri Mode 24G U.3 interface, letting the server move data at up to 24 G and maintain low latency during demanding tasks. Whether you are running dense virtual machine clusters, hosting transactional databases, or supporting file services that grow every quarter, the extra lanes of bandwidth help the server keep pace without bottlenecks.

The kit has a compact profile that measures 10 inches wide, 20.9 inches deep, and just 2.5 inches high. A build that stays lightweight at 22.93 ounces makes handling straightforward, even in a crowded rack. HPE designed the carrier to line up with the existing chassis fittings on the DL360 Gen10, so most installations finish in a short maintenance window.

IT teams in mid-size businesses, remote branch offices, and enterprise data centers can use this backplane to scale storage without replacing the entire server. It is equally practical if you are refreshing an older drive shelf, preparing for future NVMe adoption, or simply standardizing on HPE components for streamlined support and firmware management.
