Frequently Asked Questions
What primary server architectures support the HPE P10112-B21-VHBRSN OCP3 adapter? +
This OCP 3.0 form factor adapter is specifically designed for HPE ProLiant Gen10 Plus and Gen11 server platforms. Its mezzanine design optimizes airflow and simplifies installation by utilizing a dedicated OCP slot, which frees up standard PCIe slots for other expansion cards while providing high-density network connectivity.
Can I use the HPE MCX562A-ACAI with both 10GbE and 25GbE infrastructure? +
Yes, this adapter features dual-port flexibility that supports both 10GbE and 25GbE connectivity. It is fully backward compatible, allowing you to deploy it in existing 10GbE environments today while ensuring your infrastructure is ready for a seamless transition to 25GbE speeds as your bandwidth requirements grow over time.
What specific chipset powers this HPE 2-port SFP28 network adapter? +
The P10112-B21-VHBRSN utilizes the high-performance Mellanox ConnectX-5 (MCX562A-ACAI) chipset. This controller is industry-renowned for delivering low latency, high throughput, and advanced offloading capabilities, making it an ideal choice for high-performance computing, cloud-scale deployments, and virtualization environments that demand consistent, reliable network performance.
Does this card support advanced offloading technologies for virtualization? +
Absolutely. The ConnectX-5 architecture provides significant hardware-level offloads, including VXLAN, NVGRE, and Geneve overlay support. These features drastically reduce CPU overhead during heavy virtualization or software-defined networking tasks, ensuring that your host server resources remain dedicated to your primary business applications and workloads rather than network packet processing.
How does the OCP3 form factor compare to traditional PCIe network cards? +
The OCP 3.0 form factor provides a more efficient physical design compared to standard PCIe cards. It connects directly to the server's internal mezzanine slot, which improves thermal management and cable routing. This design saves valuable PCIe lanes, allowing for greater system expandability and a cleaner, more organized internal server layout.
Is RDMA supported on this HPE OCP3 adapter? +
Yes, this adapter supports RoCE (RDMA over Converged Ethernet). By enabling direct memory access between servers, it bypasses the operating system's network stack, which significantly lowers latency and increases efficiency. This is particularly beneficial for high-frequency trading, large-scale database clusters, and storage area network (SAN) traffic where timing and performance are critical.
What type of optical transceivers or cables are compatible with the SFP28 ports? +
The dual SFP28 ports support standard 25GbE optical transceivers, Direct Attach Copper (DAC) cables, and Active Optical Cables (AOC). When selecting media, ensure that you are utilizing HPE-qualified components to maintain compatibility with your server’s firmware and to ensure optimal signal integrity across your network fabric.
What management tools are required to configure the P10112-B21-VHBRSN? +
This adapter integrates directly into the HPE iLO management ecosystem. Because it is a standardized OCP 3.0 component, it is recognized by HPE server firmware during the boot process. You can configure and monitor the adapter settings through the server's System Utilities (BIOS/UEFI) or via standard industry-recognized drivers within your operating system.
How can I obtain a bulk quote for multiple HPE P10112-B21-VHBRSN units? +
