Quad 10 Gb SFP+ NIC for servers

The C&N BCM57840 network adapter adds four SFP+ ports that operate at 10 Gbps over PCI Express 3.0 x8. It fits x8 or x16 slots and targets administrators who need dense 10 Gb Ethernet connectivity for virtualised workloads or storage traffic in rack-mount servers.

Check slot width and bracket height

Your motherboard must provide a PCIe 3.0 x8 or x16 slot with enough physical clearance for a full-height bracket; the card also ships with a low-profile bracket for compact chassis. Verify that the operating system is among the supported Windows Server, Windows client, Linux or VMware ESX releases listed in the specifications.

Sustained throughput with hardware offload

On-chip TOE, SR-IOV and checksum offload move protocol processing onto the controller, keeping CPU utilisation low during continuous 10 Gb flows. Jumbo frames up to 9 KB MTU reduce per-packet overhead, while MSI-X and virtualisation queues maintain consistent latency under heavy multi-tenant load.

Domande su questo articolo

Does the card ship with SFP+ transceivers or DAC cables, or must they be purchased separately?

The box includes the network card, a driver CD, a full-height bracket and a low-profile bracket. SFP+ modules, DACs or AOCs are not included and must be bought separately.

Which PCIe slot width and generation does the BCM57840 require for full 10 Gbps performance?

The controller uses a PCI Express 3.0 x8 electrical interface and fits in either an x8 or x16 slot; it is backward compatible with PCIe 2.0 and 1.1.

What maximum frame size does the adapter support on each 10 Gbps port?

Jumbo frames up to a 9 KB MTU are supported on all four SFP+ ports for Ethernet traffic.
