HPE DL38X Gen10 Plus x16/x16 Slot 2/3 Secondary Riser Kit

The HPE P14590-B21 is a riser kit that lets you unlock two additional PCIe x16 lanes in slot 2 and slot 3 of an HPE ProLiant DL385 Gen10 Plus or DL385 Gen10 Plus Entry server. By adding these high-bandwidth connections, the kit makes it easy to install modern GPUs or other performance cards that need the full width of a x16 link.

For IT teams running graphics-heavy virtualization, machine learning experiments, or data-intensive simulations, the extra GPU capacity can remove processing bottlenecks without replacing the entire server. Engineers who need more compute power for CAD or rendering can also drop in a second card and keep projects moving instead of waiting on queues.

The kit arrives with the riser card and clear documentation, so most technicians familiar with ProLiant hardware can finish the upgrade during a planned maintenance window. Because it does not reserve room for an optical drive, every millimeter of the 14.58 cm by 24.41 cm footprint is dedicated to expansion, and the assembly adds only 0.67 kg to the chassis.

Whether you are scaling an existing cluster or building out a new rack, this straightforward riser delivers the headroom to keep pace with evolving workloads while staying inside the proven ProLiant ecosystem.
