FAQ, See What Others Asked

What wattage power supply do I need for this 25GbE network card?
This 10Gtek 25G Ethernet Network Card does not draw significant power directly from the PSU; it receives power via the PCIe slot. The primary power requirement is for your server or workstation's CPU, GPU, and other components. Add up their peak wattage draw and add approximately 20-30% headroom for future upgrades. A typical high-performance system using this card might require a 650W to 850W PSU.
Will this 25GbE network card work with Indian mains electricity?
Yes, this network card operates via the PCIe slot, which draws power from your computer's internal power supply unit (PSU). Ensure your PSU is compatible with Indian mains electricity (230V, 50Hz). Most modern ATX PSUs are auto-voltage (100-240V) and will function correctly. The card itself does not directly connect to wall power.
Is this 10Gtek 25G Ethernet Network Card compatible with macOS?
No, this 10Gtek 25G Ethernet Network Card explicitly does not support macOS. It is designed for Windows operating systems (10/11/Server), Linux distributions (CentOS, Ubuntu, RHEL, etc.), and VMware ESXi virtualization platforms.
What is RDMA and why is it important for this network card?
RDMA (Remote Direct Memory Access) allows network adapters to transfer data directly between the memory of two computers without involving the CPU. This significantly reduces latency and frees up CPU resources, which is crucial for high-performance computing, storage networks, and demanding server applications where speed and efficiency are paramount.
Can I use this network card with standard Ethernet cables?
No, this network card uses SFP28 ports, which are designed for fiber optic transceivers, Direct Attach Copper (DAC) cables, or Active Optical Cables (AOCs). It does not support standard RJ45 Ethernet cables. You will need to purchase compatible SFP28 modules or cables separately.
How do I install the low-profile bracket?
The card comes with both full-height and low-profile brackets. To install the low-profile bracket, carefully detach the full-height bracket from the card using a small screwdriver. Then, attach the low-profile bracket to the card's I/O shield area, ensuring it is securely fastened.
What is the difference between iWARP and RoCEv2 RDMA?
Both iWARP and RoCEv2 are RDMA protocols. iWARP (Internet Wide Area RDMA Protocol) runs over TCP/IP, making it easier to deploy in existing networks. RoCEv2 (RDMA over Converged Ethernet) runs over UDP and requires a lossless network infrastructure for optimal performance, often used in high-performance data centers.
