Dual 10GbE SFP+ adapter for servers

The LR-LINK LREC9812AF-2SFP+ uses a Broadcom BCM57810S controller to deliver line-rate 10Gbps Ethernet over two SFP+ cages. Hardware offload handles TCP/IP, FCoE and iSCSI workloads, reducing host CPU utilisation. It targets data-centre servers, HPC clusters and storage appliances that need converged network and storage traffic on a single fabric.

Verify PCIe 2.0 x8 slot and OS support

Your motherboard must provide a PCI Express 2.0 x8 link running at 5.0GT/s; the card also fits x16 slots. Confirm the operating system appears in the supported list: Windows 7 through 10, Windows Server 2003 R2 through 2019 R2, Linux kernel 2.6 or later, CentOS/RHEL 6.5 or later, Ubuntu 14 through 16, or VMware ESXi 4 through 6. The adapter operates from 0°C to 55°C at 5 to 95 percent non-condensing humidity.

Requires SFP+ transceivers and matching cabling

Two SFP+ modules and compatible fibre or direct-attach cables must be sourced separately to complete the links. A low-profile bracket is included for 2U or shallow chassis, while a full-height bracket suits standard servers. Offloaded protocol processing frees CPU cycles for application workloads, and Broadcom Advanced Control Suite simplifies driver and firmware management across the fleet.

Questions about this item

Does the card include SFP+ transceivers or must they be purchased separately?

The adapter provides two SFP+ cages only; compatible 10Gbps transceivers and fibre or copper cables are sold separately.

The card uses a PCIe 2.0 x8 slot — will it work in an x16 slot and do I need a low-profile bracket?

It is compatible with x16 slots and ships with both low-profile and full-height brackets for either chassis type.

What throughput can I expect from the Broadcom BCM57810S when the card is installed in a PCIe 2.0 x8 server?

The BCM57810S delivers full line-rate 10GbE on both ports with hardware TCP/IP and FCoE/iSCSI offload, limited by the 5.0 GT/s x8 bus.
