FAQ
What type of network cables does this NIC support?
This Axiom NIC supports optical fiber cables through its SFP28 ports. It is compatible with industry-standard SFP28 optical transceivers that work with both single-mode and multi-mode fiber cabling. The specific cable type and maximum distance depend on the transceiver installed, with support for 25GBase-SR (short reach) and 25GBase-LR (long reach) specifications enabling deployments from a few meters up to 10 kilometers.
Can I use this card in a standard desktop computer?
Yes, this PCIe 3.0 x8 card is compatible with any desktop computer or workstation that has an available PCIe x8 or larger slot (x16 slots are fully compatible). The included full-height bracket is designed for standard ATX cases, while the low-profile bracket accommodates smaller form factor systems. However, you'll need appropriate driver support for your operating system and compatible SFP28 transceivers with fiber network infrastructure to utilize the card's capabilities fully.
What is the difference between SFP28 and SFP+ ports?
SFP28 ports are the evolution of SFP+ ports, with both using the same physical form factor but different electrical specifications. SFP28 supports data rates up to 28 Gbit/s (25 Gbit/s for Ethernet), while SFP+ supports up to 16 Gbit/s (10 Gbit/s for Ethernet). This Axiom card uses SFP28 ports, which are backward compatible with SFP+ transceivers for 10GbE operation but require SFP28 transceivers to achieve the full 25GbE performance. The electrical interface provides better signal integrity at higher speeds compared to SFP+.
Does this NIC support link aggregation or teaming?
Yes, the dual-port configuration enables link aggregation (also called port teaming or bonding) when supported by your operating system and network switch. This allows combining both 25 Gbit/s ports to create a single logical interface with up to 50 Gbit/s of aggregate bandwidth or configure them for failover redundancy. Implementation specifics depend on your operating system's network driver capabilities and switch configuration, with most enterprise environments supporting IEEE 802.3ad (LACP) for dynamic link aggregation.
What operating systems are compatible with this network card?
This Axiom NIC with Intel XXV710 chipset is compatible with major server and desktop operating systems that have driver support for the Intel Ethernet Controller XXV710. This typically includes Windows Server editions, Windows 10/11, various Linux distributions (with kernel support), VMware ESXi, and other virtualization platforms. Always verify current driver availability for your specific OS version before deployment, as compatibility may vary with different releases and updates.
How does this 25GbE card compare to 10GbE cards for NAS storage?
This 25GbE card provides 2.5 times the throughput of standard 10GbE cards, significantly reducing data transfer times for NAS storage systems. For sequential read/write operations common in backup, media streaming, and virtual machine storage, the increased bandwidth can dramatically improve performance. The dual-port configuration also offers more flexibility for link aggregation or separate network segmentation compared to single-port 10GbE cards. However, to realize these benefits, your entire network path—including switches and other connected devices—must support 25GbE speeds.
