Dual-port 10 Gb SFP+ adapter for servers

The Vszerda card uses the Intel 82599ES controller to deliver two SFP+ ports over a PCIe 2.0 x8 interface. It supports 10 Gbps Ethernet, iSCSI, FCoE and NFS storage traffic, and is compatible with Windows Server 2003 through 2012, Windows 7 to 10, Linux and VMware ESXi. Both full-height and low-profile brackets are included for standard or slim chassis.

Sustained throughput with hardware offloads

The 82599ES provides Quality-of-Service, Flexible Port Partitioning and intelligent offload engines that maintain consistent 10 Gbps rates under continuous load. Direct Data I/O and PCI Express 2.0 5.0 GT/s x8 lanes reduce CPU overhead during long iSCSI or FCoE sessions, while data-centre bridging keeps Ethernet lossless for storage workloads.

Low power draw and broad temperature range

Typical power dissipation is 8.6 W, and the operating range spans 0 to 55 °C (32 °F to 131 °F). The dual-port design connects via SFP+ direct-attach copper, active optical or LC fibre cables up to 10 m, keeping cabling simple without adding active cooling requirements.

Questions about this item

How much heat does the 82599ES controller generate under continuous 10 Gbps load?

The card has a TDP of 8.6 W and an operating range of 0 to 55 °C (32 °F to 131 °F), so a standard server airflow path is sufficient for all-day operation.

Which SFP+ modules or cables must I supply to use the dual ports?

The dual SFP+ ports accept 10G SFP+ transceivers, direct-attach copper cables or active optical cables up to 10 m; none are included with the card.

Will the PCIe x8 interface work in my older PCIe 2.0 motherboard slot?

Yes, the adapter uses a PCI Express 2.0 x8 electrical interface (5.0 GT/s) and is compatible with x8 or x16 slots, including PCIe 2.0 platforms.
