Quad-Port 1GbE Server Adapter

The Broadcom BCM95719N1905C is a quad-port 10/100/1000BASE-T network card built to the OCP 3.0 small-form-factor specification. It targets enterprise servers and dense rack deployments that need four independent Gigabit Ethernet links from a single PCI-Express x4 slot. Each port operates as a separate PCI Express function for direct I/O assignment in virtualised environments.

Four Line-Rate Ports With Virtualisation Queues

The controller delivers full line-rate throughput across all four RJ45 ports simultaneously over a PCIe 2.1 x4 link at 5 GT/s or 2.5 GT/s. It provides 17 receive queues, 16 transmit queues and 17 MSI-X vectors to support VMware NetQueue and Microsoft VMQ, enabling workload isolation in multi-tenant hosts. Hardware assists for IEEE 1588 and 802.1AS precision time protocol are included, but the card does not offer 2.5G, 10G or fibre uplinks.

OCP 3.0 Form Factor For Dense Racks

The small-form-factor design fits OCP 3.0 cages in modern data-centre chassis, freeing full-height PCIe slots for other accelerators. A pull-tab faceplate eases installation in tool-less rail systems. The adapter requires an OCP 3.0-compliant carrier or server backplane with PCIe x4 electrical connectivity and NC-SI sideband management. It is not suited for desktop towers or workstations lacking OCP bays.

Questions about this item

Will the BCM95719N1905C run at full speed in a PCIe 2.0 x4 slot on an older server board?

The card uses PCI Express v2.1 at 5 GT/s or 2.5 GT/s, so a PCIe 2.0 x4 slot provides the same 2.5 GT/s link rate and full 1GbE line-rate on all four ports.

How can I verify the card is operating at 1Gbps on all four RJ45 ports after installation?

Check the integrated link and activity LEDs on each RJ45 connector; a steady link light and blinking activity light indicate a negotiated 1000BASE-T connection on that port.

Does the BCM95719N1905C ship with a full-height bracket or only the OCP 3.0 pull-tab faceplate?

The card includes the OCP 3.0 small-form-factor pull-tab faceplate; a full-height PCIe bracket is not included and must be purchased separately if your chassis requires it.
