DELL 81V1W Broadcom 57406 10Gbps PCIe 3.0 x8 2-Port Network Card

Dell 81V1W Dual-Port 10Gbps Adapter

The Dell 81V1W adds two 10Gbps Ethernet ports through a PCIe 3.0 x8 slot. It uses the Broadcom 57406 controller for reliable wired connectivity in servers or workstations. This adapter suits administrators who need extra high-speed network links without changing the existing infrastructure.

Sustained throughput on both ports

The Broadcom 57406 controller maintains line-rate 10Gbps traffic across both copper ports during extended transfers. PCIe 3.0 x8 bandwidth prevents the bus from becoming a bottleneck under continuous load. Thermal output stays consistent because the card draws power only from the slot.

Installation fits standard PCIe 3.0 x8 slots

The half-height bracket aligns with common server chassis and the card requires no auxiliary power cable. Driver support is built into current Linux kernels and Windows Server releases. The only frequent issue occurs when the slot negotiates at x4 instead of x8, which halves available bandwidth.
