Frequently Asked Questions

What PCI Express interface does the Intel E10G81G2P use?

This card uses a PCI Express x8 interface, providing sufficient bandwidth for full 10 Gigabit Ethernet throughput in compatible server and workstation motherboards.

Is this card designed for consumer desktop PCs or server environments?

The Intel E10G81G2P is an Ethernet Server Cluster Adapter, specifically designed for server and cluster environments where high-bandwidth, low-latency networking is critical. It can physically fit in a desktop with a PCIe x8 or x16 slot, but its driver support and feature set are tailored for server use.

What speed does this network adapter support?

It supports 10 Gigabit Ethernet, which provides up to 10 Gbps of network throughput — ten times the speed of standard Gigabit Ethernet.

Does this card require any special cabling?

As a 10 Gigabit Ethernet adapter, it typically requires appropriate cabling for the connector type — verify whether your specific unit uses SFP+ (requiring fiber or DAC cables) or RJ-45 (requiring Cat6a or Cat7 Ethernet cables) based on the port configuration.
