❓ Frequently Asked Questions

Q: Can this card work in a PCIe x16 slot?
A: Yes! This PCIe x8 network card is fully compatible with PCIe x16 slots. It will work perfectly in x8 or x16 slots on your motherboard, providing full 10Gbps performance on each port.
Q: Do I need to purchase SFP+ modules separately?
A: Yes, SFP+ transceivers (SR/LR modules) or direct attach cables (DAC) are sold separately. This allows you to choose the right connectivity option for your specific network setup - fiber optic or copper.
Q: Is this compatible with TrueNAS / FreeNAS / Unraid?
A: Absolutely! The Intel 82599ES chipset is widely supported and works excellently with TrueNAS, FreeNAS, Unraid, Proxmox, ESXi, and other popular NAS/virtualization platforms. Drivers are typically built into these systems.
Q: What's the difference between low-profile and full-height brackets?
A: Both brackets are included! The full-height bracket is for standard desktop towers and servers. The low-profile bracket is for compact/slim cases. You can easily swap between them based on your chassis requirements.
Q: Can both ports run at 10Gbps simultaneously?
A: Yes! Both SFP+ ports can operate at full 10Gbps speed simultaneously, providing up to 20Gbps total throughput. The Intel 82599ES chipset supports dual-port full-duplex operation without performance degradation.
Q: Does this card support jumbo frames?
A: Yes, the Intel 82599ES chipset fully supports jumbo frames up to 9KB (9216 bytes), which can significantly improve network performance for large file transfers and storage applications.
Q: What operating systems are supported?
A: This card supports Windows (Vista/7/8/10/11/Server), Linux (kernel 2.6+, RHEL, SLES, Ubuntu, Debian), FreeBSD, VMware ESXi, and UEFI. The Intel 82599ES has excellent driver support across all major platforms.
Q: What's the power consumption of this card?
A: The card has a maximum power consumption of 10.7W and typical power draw of 10.0W. It's powered entirely through the PCIe slot and doesn't require additional power connectors, making it ideal for energy-efficient builds.
