What PCIe slot configuration does the E610IT4M5 require?

PCIe 4.0 x8 slot with x4 x4 bifurcation support recommended for full quad-port performance. Backward compatible with PCIe 3.0 x8 slots at reduced bandwidth. Ships with both full-height and low-profile brackets for 1U/2U servers and workstations.

Does this adapter support network virtualization overlays?

Yes, provides stateless hardware offload for VXLAN, GENEVE, and NVGRE encapsulation/decapsulation. RSS and Flow Director distribute overlay traffic across CPU cores, improving throughput by 30-50% in SDN and container networking environments.

What is the power consumption at full 2.5GbE load?

Typical power 7.2W across all four ports at 2.5GbE link speed with moderate traffic. Maximum 8.6W under heavy load. Low thermal design suits dense server deployments without requiring additional cooling or power budgeting concerns.

Is SR-IOV supported and how many virtual functions?

SR-IOV supported with up to 64 virtual functions per port, enabling direct NIC assignment to VMs. Combined with VMDq and Flexible Port Partitioning, supports 1000+ VMs per server with optimal I/O isolation and QoS enforcement.

What cabling standards are supported?

CAT5e for 100Mb/1GbE up to 100m, CAT6/CAT6A for 2.5GbE up to 100m. Auto-MDIX and auto-negotiation ensure plug-and-play compatibility with existing enterprise cabling infrastructure without recabling requirements.

What security features protect against firmware attacks?

Hardware Root of Trust anchors SPDM 1.2 attestation and FIPS 140-3 Level 1 cryptography. Secure boot verifies firmware signatures, recovery mode handles corruption, and NIST SP 800-193 compliant platform resiliency prevents supply chain attacks.

Product overview

The Intel Ethernet Network Adapter E610-IT4 (E610IT4M5 multi-pack) is a quad-port PCIe 4.0 x8 network card designed for enterprise server and workstation deployments requiring high-density 2.5GbE connectivity. Featuring four RJ45 copper ports supporting 2.5GbE, 1GbE, and 100Mb speeds with backward compatibility over CAT5e/CAT6/CAT6A cabling up to 100m, it enables cost-effective multi-gigabit upgrades without recabling. Powered by the Intel Ethernet Controller E610-IAT2, the adapter supports PCIe 4.0 x8 via x4 x4 bifurcation for optimal slot utilization. Key enterprise features include Intel Virtualization Technology for Connectivity (VT-c), SR-IOV with up to 64 virtual functions per port, Virtual Machine Device Queues (VMDq), and Flexible Port Partitioning for efficient VM isolation and I/O scalability. Advanced offloads like Intel Data Direct I/O, Intelligent Offloads, and Flow Director optimize CPU usage in virtualized environments. Network virtualization overlay support for VXLAN, GENEVE, and NVGRE with stateless offload enhances cloud and NFV performance. Security includes hardware Root of Trust, SPDM 1.2 device attestation, FIPS 140-3 Level 1 compliance, and secure boot/firmware updates. Ideal for communications, cloud, and enterprise IT with low power consumption (typical 7.2W at 2.5GbE), FCC Class B certification, and broad OS/hypervisor compatibility including extensive x86 validation. Provides excellent small packet performance for NFV appliances and high-throughput overlay networks.
