Network Card MicroConnect X520-DA2 PCIe x8 SFP+ – dual-port 10GbE server adapter

MicroConnect X520-DA2 PCIe x8 SFP+ is a dual-port 10 Gigabit Ethernet server adapter designed for installation in a PCIe x8 slot. The card provides two SFP+ ports for fiber or direct-attach copper transceivers, enabling high-throughput connectivity for virtualization hosts, storage servers and data center racks. It supports standard 10GbE networking functions, link aggregation and low-latency packet processing suitable for enterprise server environments.

Advantages

The adapter delivers dual 10GbE ports in a low-profile PCIe x8 form factor, allowing increased network bandwidth without occupying larger slots. SFP+ ports offer flexibility to choose between optical modules and DAC cables for varying cable lengths and environments. The design reduces CPU overhead through optimized offload features and supports aggregated links to improve throughput and redundancy.

Suitable for

• Virtualization hosts and hypervisor servers requiring higher uplink bandwidth
• Storage servers and NAS systems performing large data transfers
• Aggregation of multiple 10GbE links for increased throughput or redundancy
• High-performance computing nodes and database servers with heavy network I/O
• Data center switches or top-of-rack connectivity where SFP+ transceivers are used

Key specifications

• Interface: PCI Express x8 (logical x8 lane width)
• Network ports: 2 × SFP+ 10 Gigabit Ethernet
• Supported speeds: 10 Gbps per port
• Form factor: Low-profile bracket compatible with standard server chassis
• Typical functions: Link aggregation, VLAN tagging, checksum offload, TSO/LRO support
• Compatibility: Designed for server-class operating systems and hypervisors

How to use

Install the adapter into an available PCIe x8 slot or a compatible x16 slot on the server motherboard, secure the bracket and connect appropriate SFP+ transceivers or DAC cables to the SFP+ ports. Configure network settings in the server operating system or hypervisor, create link aggregation or VLANs as required, and verify that drivers and firmware are up to date for full feature support. Reboot the server if required by the OS or driver installation process.

Recommendations

For reliable 10GbE operation, use certified SFP+ modules or DAC cables that match your cabling distance and type. Keep firmware and drivers updated, enable offload features when supported by your OS to reduce CPU load, and consider link aggregation for redundancy or increased throughput in clustered or storage environments.
