Frequently Asked Questions
What primary performance benefit does the HPE 100Gb OP101 Omni-Path adapter offer for HPC environments? +
The HPE 100Gb OP101 adapter is designed specifically for High Performance Computing (HPC) clusters. It utilizes Intel Omni-Path Architecture to deliver high bandwidth, low latency, and enhanced message rate performance. This allows for superior scaling and improved application throughput in data-intensive workloads like scientific modeling, simulations, and financial analytics that require rapid node-to-node communication.
Does the 829335-B21 require a specific PCIe slot configuration? +
Yes, this adapter utilizes a PCIe Gen3 x16 interface to achieve its maximum throughput of 100Gbps. It is essential to install the card in a compatible PCIe Gen3 x16 slot to avoid bottlenecks. Ensure your server motherboard supports the x16 electrical lane configuration to guarantee the adapter functions at its full rated speed and performance capacity.
What type of physical cabling is supported by the QSFP28 port on this Omni-Path adapter? +
The OP101 adapter features a single QSFP28 port, which is the industry standard for 100Gb connectivity. You can utilize either passive or active copper direct-attach cables (DAC) for short-reach, top-of-rack connections, or fiber-optic QSFP28 transceivers for longer distances. Ensure that your cabling infrastructure is compatible with the Intel Omni-Path standard to maintain signal integrity.
Is this Intel Omni-Path adapter compatible with standard Ethernet network protocols? +
The HPE OP101 adapter is purpose-built for the Intel Omni-Path fabric architecture rather than standard Ethernet networking. It uses a proprietary high-performance interconnect protocol designed to offload communication tasks from the CPU. Consequently, it is intended for use in specialized HPC fabrics and will not function as a standard 100Gb Ethernet NIC in a conventional enterprise LAN environment.
What is the physical form factor of the HPE 829335-B21 adapter? +
This adapter follows a standard PCIe half-height/low-profile form factor. This compact design makes it highly versatile, allowing it to be installed in a wide range of HPE ProLiant servers, including both rack-mount and high-density blade configurations where vertical space is constrained. It typically includes both full-height and low-profile brackets to accommodate different chassis requirements.
How does Omni-Path architecture reduce CPU overhead during data transfers? +
Omni-Path Architecture minimizes CPU intervention by utilizing advanced hardware offload engines that manage data packets directly. By offloading critical communication protocols from the host processor, the adapter ensures that more CPU cycles remain available for actual application processing. This efficient design significantly reduces latency and jitters, which is vital for maintaining synchronization across large-scale computing clusters.
What are the power consumption considerations for the OP101 100Gb adapter? +
As a high-performance 100Gb NIC, the OP101 is engineered for efficiency within HPE server thermal envelopes. While the power draw is optimized for PCIe Gen3 slots, it is recommended to review your server's total power budget, especially in dense configurations with multiple cards installed. Proper chassis airflow is critical to maintain optimal operating temperatures and ensure long-term hardware reliability.
Which HPE server families are certified for use with the 829335-B21 card? +
The 829335-B21 is generally qualified for use with HPE ProLiant DL, ML, and Apollo server lines that support Intel Omni-Path integration. It is highly recommended to consult the specific server quickspecs or compatibility matrix for your model to confirm verified support and ensure the necessary firmware levels are installed to support the Omni-Path fabric architecture.
