Value Brand 10Gb Dual SFP+ PCIe 2.0 x8 Network Card BCM57810S

Dual 10Gb SFP+ Ports

This PCIe 2.0 x8 network card adds two 10Gb SFP+ ports to a server or workstation. It is built around the Broadcom BCM57810S controller and supports SR-IOV for virtualised workloads. The card fits both standard and low-profile slots thanks to the included brackets. It targets administrators who need 10Gb connectivity without moving to a newer bus generation.

PCIe 2.0 x8 Bandwidth

The x8 lane interface delivers 5.0 GT/s per lane, which is sufficient for dual 10Gb line-rate traffic under typical loads. Heavy simultaneous bidirectional streams can saturate the bus because the 2.0 generation caps total throughput below the theoretical maximum of two full 10Gb links. Users planning sustained wire-speed on both ports should verify their platform provides a true x8 electrical connection rather than a physical x16 slot wired for fewer lanes.

Broad OS Compatibility

Drivers are supplied for Windows 7 through 10, Windows Server 2008 through 2019, Linux distributions including CentOS, RHEL, Ubuntu, Debian and SLES, plus FreeBSD and VMware ESXi 6 and 7. The card does not support operating systems released after the listed versions, so deployments on newer hypervisors or distributions may require manual driver integration. Buyers needing guaranteed out-of-the-box support for current releases should confirm compatibility before purchase.
