Intel Ethernet Network Adapter X710-DA4 10GbE Quad-Port SFP+

The Intel Ethernet Network Adapter X710-DA4 (part number X710DA4) is a quad-port 10 Gigabit Ethernet adapter built on Intel's XL710 controller silicon, offering four SFP+ ports in a full-height, half-length PCIe 3.0 x8 form factor. The adapter delivers up to 40 Gbps aggregate throughput across its four ports and incorporates Intel's Data Plane Development Kit (DPDK) support, SR-IOV with up to 128 virtual functions, and hardware-offloaded features including checksum offload, VXLAN and GENEVE tunnel endpoint offload, and flow director for precise receive-side packet steering. These capabilities reduce CPU overhead and enable consistent, low-latency packet processing at line rate across all four ports simultaneously.

Designed for demanding enterprise and telecom environments, the X710-DA4 supports IEEE 802.3ae 10GBASE-R and is compatible with Intel-qualified SFP+ optical transceivers and direct-attach copper (DAC) cables. The adapter implements PCI-SIG SR-IOV to partition physical ports into up to 128 virtual functions per port, making it well suited to dense virtualization deployments where multiple virtual machines or containers require dedicated, isolated network paths. IEEE 802.1Q VLAN tag insertion and stripping, IEEE 802.3ad link aggregation, and RDMA over Converged Ethernet (RoCE v2) via iWARP are supported, enabling converged storage and compute traffic on a common fabric.

The X710-DA4 carries broad operating system and hypervisor support, including Linux kernel drivers (i40e), Windows Server, VMware ESXi, and FreeBSD, and integrates with Intel Ethernet Converged Network Fabric management tooling. The adapter operates across the standard enterprise server temperature range and is qualified for deployment in rack servers, blade server mezzanine configurations, and telecommunications network function virtualization (NFV) platforms. Its combination of multi-port density, hardware offload depth, and SR-IOV scalability has made it a long-running standard component in high-throughput server connectivity since its introduction in early 2017.

Ideal for

• High-density server virtualization requiring SR-IOV-backed dedicated virtual NICs for up to 128 VMs per physical port without hypervisor software switching overhead
• Network Function Virtualization (NFV) and telecom edge platforms running virtual routers, firewalls, or load balancers that depend on DPDK-accelerated packet I/O at 10 Gbps line rate
• Converged storage and compute fabrics leveraging iWARP RoCE v2 for low-latency NVMe-oF or iSCSI storage traffic alongside application network traffic on a shared 10GbE infrastructure
• Large-scale cloud and enterprise data center top-of-rack server connectivity where quad-port density reduces adapter slot consumption and cabling complexity across high-core-count servers
• High-performance computing (HPC) clusters and analytics workloads requiring consistent low-latency, high-throughput east-west traffic between nodes with hardware-offloaded VXLAN overlay encapsulation
• Telecommunications and carrier-grade infrastructure requiring deterministic latency, precise traffic classification via Flow Director, and compliance with IEEE 802.1Q/802.3ad standards
