Dual 10Gbps SFP+ server adapter

The LR-LINK LREC9802BF-2SFP+ is a PCI Express x8 network card with two SFP+ ports, each running at 10 Gbps. It is built on the Intel 82599ES controller and targets servers that need high-throughput wired links for virtualisation or unified storage workloads. The card fits both low-profile and full-height brackets and operates from 0 °C to 55 °C. It supports Windows 7 through 10, Windows Server 2003 R2 through 2019 R2, Linux kernels 2.6 and later, plus VMware ESXi 4.x and newer.

Multi-core optimisation and virtualisation support

The adapter uses multiple queues, receive-side scaling, multiple MSI-X vectors and low-latency interrupts to spread packet processing across CPU cores. This architecture reduces bottlenecks when many virtual machines share the same physical host. The driver stack is validated on CentOS/RHEL 6.5 and 7, Ubuntu 14 through 16, and the listed Windows Server releases, so deployment on existing hypervisors is straightforward.

PCI Express 2.0 x8 interface requirement

The card needs a PCIe 2.0 x8 slot running at 5.0 GT/s, though it is also compatible with x16 slots. If your server only offers x4 or PCIe 1.0 lanes, the adapter will not reach its rated throughput. Verify the slot width and generation before purchase.

Questions about this item

Will the Intel 82599ES controller on the LREC9802BF-2SFP+ need a firmware update later?

The card uses the Intel 82599ES controller; firmware updates are handled through the operating system driver stack when a new driver version is installed.

What limits sustained 10 Gbps throughput on the PCI Express 2.0 x8 interface?

The PCIe 2.0 x8 link provides 5.0 GT/s bandwidth, which matches the dual 10 Gbps ports so the bus is not the first bottleneck under load.

How much heat does the dual-port 10G card produce when running all day in a 55 °C environment?

Operating temperature is rated 0 °C to 55 °C; the low-profile design relies on chassis airflow to keep the Intel 82599ES controller within that range during continuous operation.
