StarTech.com PEX10GSFP4I 10G SFP+ x4 Server

When your server or workstation stalls because the existing Ethernet link can’t keep up with growing data demands, adding a high-speed interface is the fastest fix. The StarTech.com PEX10GSFP4I 10G SFP+ x4 Server is a PCIe network card that gives you four open SFP+ slots, letting you choose the exact fibre modules you need for a reliable 10 Gigabit connection.

Usages of a 20Gbps network card

Ideal for data-centre servers, high-performance workstations and virtualisation hosts, this card lets you attach multiple fibre links for load-balancing, redundancy or separate traffic streams, ensuring continuous uptime during peak workloads.

Benefits of StarTech.com network card

• Redundancy: Fault-tolerant connections keep your services online even if one link fails.
• Speed: Up to 10 Gbps per port delivers rapid data transfers for large files and backups.
• Flexibility: Choose multimode or single-mode SFP+ modules to match distance and connector needs.
• Scalability: Four ports let you expand bandwidth as your network grows without replacing the card.
• Management: Intel® XL710 chipset supports virtualization, PXE boot and jumbo frames for smoother operations.

StarTech.com network card

Choosing this card means you get a proven Intel® XL710 chipset, renowned for stability and advanced features like Virtualisation Technology for Connectivity. The PCI Express x8 interface ensures the card can handle the full 20 Gbps aggregate throughput without bottlenecks, making it a solid upgrade over older 1 GbE adapters.

Because the card accepts any standard 10GBase-LR SFP+ module, you can start with a short-reach multimode fibre for the office and later switch to long-reach single-mode modules as your campus expands. The included Connectivity Tools software adds extra security with MAC address pass-through and lets you quickly switch to wired LAN for faster speeds when needed.
