Dual SFP+ 10 GbE server adapter

This Value Brand add-in card brings two 10 Gb SFP+ ports to a server or workstation through an x8 PCI Express 2.0 slot. The Intel 82599ES controller handles traffic and supports Single Root I/O virtualisation for multi-tenant environments. Both low-profile and full-height brackets are included for standard or slim chassis.

Sustained throughput on dual ports

Each SFP+ cage accepts 10 Gb transceivers, direct-attach cables or active optical cables at the full 5.0 GT/s lane rate. The x8 electrical interface delivers enough bandwidth to keep both ports active at line rate without PCIe bottlenecking. Driver support spans Windows 7 through Server 2019, Linux kernels back to 2016, FreeBSD 10 through 12 and VMware ESXi 6 and 7.

PCIe 2.0 x8 interface ceiling

The card operates at PCI Express 2.0 speeds, so total bidirectional throughput is limited to the 5.0 GT/s x8 link rather than newer 3.0 or 4.0 rates. Slots wired for x4 or x1 will negotiate down and reduce maximum aggregate bandwidth accordingly. Compatibility extends to x8 and x16 physical slots across supported operating systems listed in the specifications.

Domande su questo articolo

Does the Intel 82599ES controller generate much heat when the 10Gb ports run continuously?

The card uses the Intel 82599ES controller with a passive heatsink. It is designed for server workloads and runs within normal PCIe thermal limits when installed in a chassis with standard airflow.

Which SFP+ modules or cables do I need to buy separately for the dual 10Gb ports?

The dual SFP+ ports accept 10G SFP+ transceivers, direct-attach copper cables (DAC) or active optical cables (AOC). Choose the media type that matches your switch and distance requirements.

Will the x8 PCIe 2.0 interface work in my older motherboard that only has x4 or x16 slots?

The card fits x8 and x16 slots electrically and mechanically. In an x4 slot it will negotiate down to x4 lanes at 5.0 G T/s per lane, reducing maximum throughput but remaining functional.
