Quad-Port 10GbE SFP+ Server Adapter

The LR-LINK LREC9804BF-4SFP+ is a quad-port 10 Gigabit Ethernet server adapter built on the Intel XL710-BM1 controller. It connects through a PCI Express 3.0 x8 slot to provide four SFP+ cages for fibre or direct-attach copper links. The card targets administrators who need dense 10 GbE connectivity in virtualised server and storage networks. It operates from 0°C to 55°C in non-condensing humidity up to 95%.

PCIe 3.0 x8 Bandwidth Constraint

The adapter requires a PCI Express 3.0 x8 slot to deliver full throughput across all four ports. A narrower slot or an older generation link will limit aggregate bandwidth below the combined 40 Gbps potential of the four 10 GbE ports. Small-packet workloads reach wire rate above 64 bytes per frame, while bulk transfers sustain line rate with low CPU utilisation. Wake-on-LAN is not supported on this model.

Intel XL710-BM1 Controller Determines Compatibility

The single specification that decides fit is the Intel XL710-BM1 controller, which dictates driver support, virtualisation offloads and SFP+ module interoperability. Buyers needing a different controller feature set or a port count other than four should select another adapter. The card is classified for 10G and PCIe environments and ships new.

أسئلة حول هذا المنتج

Should I pick a dual-port or this four-port 10Gbps SFP+ card?

Choose the four-port model when you need four independent 10Gbps links in a single PCI Express v3.0 x8 slot; a dual-port card only provides two.

What does the 10Gbps rating mean once the card is installed in a server?

Each of the four SFP+ ports can sustain line-rate 10Gbps throughput with low CPU overhead, and the Intel XL710-BM1 controller achieves wire-rate on packets larger than 64 bytes.

Does the PCI Express v3.0 x8 interface limit total bandwidth in practice?

The x8 lane provides enough headroom for all four 10Gbps ports to run simultaneously at line rate without bottlenecking the bus.
