Frequently Asked Questions
What is a 40Gb dual-port network interface card used for?
A 40Gb dual-port NIC is designed for high-performance data center applications including server virtualization, storage networking, high-frequency trading platforms, and large-scale data processing. The dual QSFP+ ports enable redundancy, load balancing, or dedicated traffic segregation in enterprise environments.
Is this 40Gb network card compatible with my existing infrastructure?
Yes, this ENET card is Silicom PE340G2Qi71 compatible, meaning it works as a drop-in replacement or upgrade for systems currently using that model. Verify your server supports PCIe x8 slots and has appropriate QSFP+ optical modules or DAC cables for your connectivity needs.
What drivers and operating systems are supported?
The Intel XL710 chipset benefits from extensive driver support across Linux, Windows Server, and ESXi environments. Check the ENET SOLUTIONS support portal and Intel's driver repository for the latest versions compatible with your specific OS and kernel version.
Can I use this PCI Express x8 card in a PCIe x16 slot?
Yes, the PCIe x8 network interface card is backward compatible with x16 slots and will operate at x8 speeds. It will not achieve x16 performance, but provides full 40Gbps per-port throughput as designed.
