If you’re deploying virtualization, databases, or software-defined storage on ML350 Gen11, this riser kit helps you maximize efficiency, improve deployment timelines, and future-proof your infrastructure with certified HP compatibility.

• Unlock expanded PCIe capacity — This kit introduces two 8-lane PCIe pathways that expand the ML350 Gen11’s I/O surface, enabling flexible addition of network interface cards, storage controllers, and acceleration devices. By offloading I/O tasks to dedicated PCIe lanes, you can reduce bottlenecks in data-intensive workloads, boost throughput for virtualized environments, and improve data movement across internal components. The design preserves signal integrity across high-speed PCIe links and is tuned for predictable behavior under heavy multi-threaded workloads, which is essential for demanding enterprise applications and dense virtual environments.
• Designed for enterprise reliability — Reliability is at the core of HP ProLiant platforms, and this tertiary riser kit upholds that standard with rugged connectors, durable PCB traces, and secure mounting hardware. It’s engineered to withstand vibration, thermal cycling, and routine maintenance cycles common in 24/7 data centers. By maintaining stable PCIe lanes and reducing the risk of misalignment during installation, the kit supports dependable operation for mission-critical workloads and long operational lifecycles, aligning with HP’s service and warranty ecosystems.
• Seamless integration with ML350 Gen11 architecture — The kit is purpose-built for the ML350 Gen11 chassis, featuring an optimized form factor and connector layout that aligns with the server’s midplane architecture. This ensures effortless seating, clean cable routing, and minimal downtime during upgrades. The tertiary riser aligns with the Gen11 design language to deliver consistent electrical performance, improved airflow, and straightforward serviceability, allowing IT teams to perform upgrades without significant rework to surrounding components.
• Ideal for data center scale-out — In environments where consolidation, virtualization, or database acceleration drives ROI, additional PCIe capacity unlocks meaningful performance gains. The 2x8 Riser Kit enables you to support more NICs for virtual networks, add storage controllers for enhanced IOPS, or deploy accelerators for analytics workloads without needing a full motherboard upgrade. This translates to higher effective compute density per rack, easier workload balancing, and greater adaptability to changing IT requirements as your data center grows.
• Warranty, support, and future-proofing — As part of the HP ProLiant ecosystem, the 2x8 Tertiary Riser Kit comes with status-quo HP warranty options and access to HP’s global support network. The design anticipates firmware and driver updates to maintain compatibility with evolving Gen11 firmware stacks, ensuring your investment remains aligned with supported configurations and ongoing product roadmaps as you scale your ML350 Gen11 deployments.
