Overview The HPE P14600-B21 is a Slot1 x16 Adder for Slot2/3 Riser Kit designed to expand the PCI Express capacity inside select HPE ProLiant Gen10 Plus servers. It adds an additional full-width PCIe x16 slot, enabling the installation of high-performance adapters such as graphics accelerators, high-speed network cards, or storage controllers. This riser kit is compatible with the DL380 Gen10 Plus and DL385 Gen10 Plus server families, ensuring seamless integration and reliable operation. Its compact size and lightweight design allow it to fit without disrupting airflow or system balance, making it a practical upgrade for administrators who need to increase server I/O capabilities without moving to larger chassis or adding more servers. Key features Expands server capacity by adding one PCI Express x16 slot through the Slot1 position Compatible with HPE ProLiant DL380 Gen10 Plus and DL385 Gen10 Plus servers, including Network Choice and Entry models Supports installation of GPUs, network interface cards, or storage controllers requiring full-width bandwidth Tool-less installation that integrates smoothly with existing riser hardware and server cooling systems Minimal impact on airflow and system balance due to its compact footprint and light weight Allows quick BIOS recognition of the new slot for immediate use and minimal downtime Key specs Form factor: Slot1 x16 Adder for Slot2/3 Riser Kit Compatible servers: HPE ProLiant DL380 Gen10 Plus, DL385 Gen10 Plus Dimensions: 3.4 cm × 13.36 cm × 2.29 cm Weight: 0.48 kg Interface: PCI Express x16 slot Installation and setup The riser kit installs quickly without tools, sliding into the designated bay within the server chassis. It connects with existing power and cooling pathways, ensuring the server maintains optimal thermal performance. Once installed, the additional PCIe slot is immediately recognized by the server BIOS, allowing administrators to add compatible expansion cards without extended downtime or complex configuration. Ideal uses and environments This riser kit is well suited for data centers and enterprise environments where server I/O demands grow over time. It supports workloads such as virtualization hosts, database servers, and high-density compute clusters that require additional network bandwidth, GPU acceleration, or expanded local storage. By enabling extra PCIe slots within the same chassis, it helps maximize hardware investment and delay costly server replacements or expansions.
