Frequently Asked Questions

What primary connectivity standards does the HPE 841QSFP28 adapter support? +

The HPE P02012-B21 is a versatile network interface card that supports both InfiniBand EDR and Ethernet 100Gb connectivity. This dual-protocol capability allows data centers to deploy the card in high-performance computing clusters utilizing InfiniBand for low-latency messaging or standard Ethernet environments for high-bandwidth traffic, providing maximum flexibility for modern enterprise infrastructure.

Which specific form factor is the HPE 841OCP designed for? +

This adapter features the Open Compute Project (OCP) form factor, specifically engineered to slide into dedicated OCP slots on compatible HPE ProLiant servers. By utilizing the OCP architecture, this NIC leaves standard PCIe expansion slots available for other critical hardware, optimizing internal chassis airflow and maximizing the port density of your server rack.

Can I use the HPE 841OCP QSFP28 for storage-heavy enterprise workloads? +

Absolutely. With 100Gbps bandwidth, this NIC is an excellent choice for storage-heavy environments such as NVMe-over-Fabrics or high-speed NAS deployments. The high throughput and low-latency performance ensure that your storage arrays remain responsive, effectively eliminating bottlenecks when handling massive datasets, real-time database transactions, or intensive virtual machine migrations across your network fabric.

What type of physical cabling is required for the 100Gb port on this card? +

The card utilizes a QSFP28 interface, which supports high-speed 100Gb connectivity. You can deploy this using Direct Attach Copper (DAC) cables for short-reach, top-of-rack connections, or utilize active optical cables (AOC) and standard optical transceivers for longer distances within your data center. Always ensure your chosen optics or cables are compatible with the QSFP28 standard for optimal link stability.

Does this adapter support advanced offloading technologies for CPU efficiency? +

Yes, the 841OCP is engineered to offload significant networking tasks from the server CPU. By handling complex packet processing and protocol-specific tasks directly on the card, it reduces host processor utilization. This is particularly beneficial for virtualization and cloud environments, where minimizing CPU overhead is essential for maintaining the performance of guest operating systems and application workloads.

How does the HPE 841OCP contribute to lower data center latency? +

By providing EDR InfiniBand support, this card enables Remote Direct Memory Access (RDMA). RDMA bypasses the operating system's kernel stack to move data directly between the memory of two servers. This significantly decreases latency and jitter, making the 841OCP ideal for distributed applications that require split-second responses and high-performance message passing within a clustered computing environment.

Is the HPE 841OCP compatible with standard HPE server management tools? +

The card integrates seamlessly with the HPE ecosystem, allowing administrators to monitor and manage the adapter through familiar management interfaces. This integration simplifies lifecycle management and allows for consistent firmware updates and performance monitoring, ensuring that the NIC remains aligned with the operational standards of the rest of your ProLiant server fleet.

What should I consider when deploying the 841OCP in a high-density server rack? +

When deploying in high-density environments, ensure your server’s power budget and cooling systems are optimized for the thermal profile of 100Gb components. Because the OCP design is optimized for airflow, verify that the server chassis configuration supports the airflow requirements of your high-speed interconnects to maintain peak performance and hardware longevity under heavy, continuous network loads.

How can I obtain a bulk quote for multiple HPE 841OCP units? +
