Know before you buy
This adapter features two SFP28 slots, which are designed for optical fiber media. You will need to use compatible SFP28 optical transceivers or direct-attach copper (DAC) cables that match your switch infrastructure.
Yes, the adapter is highly versatile. It ships with both low-profile and full-height brackets, allowing it to be installed in almost any standard server chassis, including compact 1U systems.
These technologies allow the adapter to transfer data directly between server memory without involving the CPU. This significantly reduces latency and lowers CPU overhead, which is ideal for high-performance storage and virtualization workloads.
Yes, the card includes SR-IOV support, which allows you to partition the physical adapter into multiple virtual functions. This improves network efficiency and performance when running multiple virtual machines on a single server.
While the card utilizes a PCIe 4.0 interface for maximum throughput, it is generally backward compatible with older PCIe generations. However, using it in an older slot may limit the total bandwidth available to the card.
SFP28 ports are often backward compatible with SFP+ transceivers, but you should verify the specific compatibility of your switch and transceiver modules. Generally, this card is optimized for 25GbE environments.
