Network adapter Dell Intel X520 DP 10Gb DA/SFP dual port

Dell Intel X520 DP 10Gb DA/SFP dual port is a PCIe network adapter that provides two 10 Gigabit Ethernet ports compatible with Direct Attach (DA) copper and SFP+ modules. Designed for servers and workstations, this Dell-branded card offers high-throughput, low-latency connectivity suitable for virtualization, storage networks, and network aggregation in data center and enterprise environments. The compact PCIe form factor and dual-port layout enable straightforward installation and reliable 10Gb links for demanding network tasks.

Advantages

The adapter delivers dual 10Gb ports to increase uplink capacity and enable link redundancy or load balancing. Support for both DA copper and SFP+ modules provides deployment flexibility across short-reach copper and fiber connections. As a server-focused NIC, it is engineered to offer low latency and consistent throughput for virtualized workloads and storage traffic while maintaining compatibility with standard PCIe slots.

Suitable for

• Server uplinks and top-of-rack aggregation
• Virtualization hosts and hyper-converged infrastructure
• iSCSI, NAS and SAN storage networking
• High-throughput application servers and database servers
• Network interface redundancy and link aggregation (LACP)
