Dual 10Gb ports deliver stable throughput and low latency. Perfect for virtualization and storage traffic.
Seamless OCP integration with consistent network reliability in production.
Strong 10 Gigabit performance with excellent driver stability.
Reliable adapter providing predictable bandwidth during peak loads.
Great enterprise networking solution with smooth deployment experience.
The X520-DA2 is a dual-port 10 Gigabit Ethernet PCIe 2.0 x8 server adapter designed for high-performance, low-latency network connectivity in enterprise and data center environments.
The adapter uses a PCI Express 2.0 x8 interface, providing up to 4 GB/s of bidirectional bandwidth for demanding network applications.
It supports 1 GbE and 10 GbE speeds, auto-negotiating to match connected switch or server port rates for maximum flexibility.
The X520-DA2 features two SFP+ ports, enabling simultaneous connections to two 10 GbE fiber or DAC links.
It is compatible with 10 GbE SR/LR/LRM fiber transceivers and Direct Attach Copper (DAC) cables for up to 7 meters of copper connectivity.
Intel provides drivers for Windows Server, various Linux distributions (RHEL, CentOS, Ubuntu), VMware ESXi and FreeBSD for broad platform compatibility.
Yes, it includes Intel® Virtualization Technology for connectivity (VT-c), supporting SR-IOV and VMDq for efficient VM traffic management.
Typical power consumption is around 7 W under load, with idle power as low as 4 W, optimizing energy efficiency in 24/7 operations.
No, the adapter is not hot-swappable; the host server must be powered down or in a maintenance state before installation or removal.
The full-height bracket card measures 167 mm × 69 mm, and a low-profile bracket is included for 2.7″ slot compatibility.
Power off the server, insert the card into an available PCIe 2.0 x8 slot, secure the bracket, install the appropriate OS driver and reboot.
It supports Intel® Ethernet Manager, SNMP, RMON, IEEE 802.1q VLAN tagging and flow control for comprehensive network administration.
Intel offers a three-year limited hardware warranty covering defects in materials and workmanship under normal use.
With features like Adaptive Load Balancing, IEEE 802.3ad Link Aggregation Control (LACP) and fault tolerance, the adapter ensures continuous uptime and redundancy.
It includes TCP/IP checksum offload, Large Send Offload (LSO), Receive Side Scaling (RSS) and iSCSI/RDMA acceleration for CPU offload and high throughput.
