Frequently Asked Questions
Q: Will this card work in a PCIe x16 slot?
A: Yes, this network adapter is fully compatible with both PCIe x8 and x16 slots. It will operate at x8 speeds when installed in either slot type, providing maximum flexibility for your server configuration.
Q: Do I need to download and install drivers?
A: Yes, driver installation is required for optimal performance. Please download the Intel XL710 driver from the link provided above. While some operating systems include basic drivers, installing the latest official driver ensures full feature support and best performance.
Q: Can I use both ports simultaneously for 80Gbps total bandwidth?
A: Yes, both QSFP+ ports can operate simultaneously, providing up to 80Gbps aggregate bandwidth (40Gbps per port). You can configure them for link aggregation (LACP), separate networks, or redundancy depending on your requirements.
Q: Does this card support SR-IOV for virtualization?
A: Yes, the Intel XL710-T2 controller fully supports SR-IOV (Single Root I/O Virtualization), allowing you to create multiple virtual functions for direct VM access. This significantly improves network performance in VMware, Hyper-V, and KVM environments.
Q: What is the power consumption of this network card?
A: The Intel XL710-T2 network adapter typically consumes approximately 15-20W under full load. Actual power consumption varies based on workload, link speed, and configuration. It meets PCIe power specifications and does not require additional power connectors.
Q: Is a low-profile bracket included for 2U/1U servers?
A: Yes, this package includes a low-profile bracket, making it compatible with both standard full-height and low-profile server chassis. You can easily swap the bracket to fit your specific server form factor.
Q: Can this card be used with TrueNAS or FreeNAS?
A: Yes, the Intel XL710 chipset is well-supported in FreeBSD-based systems including TrueNAS and FreeNAS. The ixl driver is included in recent versions, providing excellent performance for high-speed storage networking and NAS applications.
