Scheda di rete MicroConnect X520-DA1 PCIe x4 — dual port 10GbE SFP+

The MicroConnect X520-DA1 PCIe x4 — Dual-Port 10GbE SFP+ is a network interface card designed to add two 10 Gigabit Ethernet SFP+ ports to servers and workstations. It fits into a standard PCIe x4 slot and provides high-throughput, low-latency connectivity suitable for demanding network tasks such as virtualization, high-speed file transfer and storage networking. The card is intended for use where reliable 10GbE uplinks are required to improve overall network performance in professional and data center environments.

Advantages

The dual SFP+ ports enable simultaneous connections for redundancy or aggregated throughput, while the PCIe x4 interface keeps slot usage efficient. The design focuses on stable 10GbE links with low latency and consistent throughput, making it suitable for mixed workloads. Compatibility with common SFP+ transceivers and passive direct-attach cables provides deployment flexibility in existing infrastructures.

Suitable for

• Server uplinks in data centers and rack environments
• High-speed storage networks (iSCSI, NFS)
• Virtualization hosts and hypervisors
• Workstations requiring fast file transfer and low-latency connectivity
• Link aggregation and redundant network paths

Key specifications

• Interface: PCI Express x4 (physical form factor compatible with PCIe x4 slots)
• Network ports: 2 × 10 Gigabit Ethernet SFP+ ports
• Supported link speed: 10 Gbps per port
• Form factor: Low-profile bracket compatibility for compact chassis
• Latency: Optimized for low-latency packet forwarding and high throughput
• Connectivity options: Supports SFP+ modules and passive/direct-attach cables

How to use

Install the MicroConnect X520-DA1 into an available PCIe x4 slot on a powered-down system, secure the bracket, and attach compatible SFP+ transceivers or direct-attach cables to the ports. After booting the operating system, install or enable the appropriate network drivers and configure network settings such as IP addressing, MTU, and link aggregation if needed. Verify link status and speed through the operating system network tools or management interfaces to confirm 10GbE connectivity.

Recommendations

For stable 10GbE performance, use quality SFP+ transceivers or certified direct-attach cables and keep firmware and drivers up to date. Configure proper cooling and airflow in server chassis to maintain optimal operating temperatures. When deploying in production, test link aggregation and failover scenarios to ensure redundancy and performance meet workload requirements.
