  • Virtualization queues accelerate VMware NetQueue and Microsoft VMQ performance
  • PCI Express interface provides dedicated bandwidth to each port
  • IEEE 1588 hardware support enables precise network time synchronisation

Quad-port 1GbE server NIC

The Broadcom BCM95719A1904AC is a quad-port Gigabit Ethernet adapter that installs in a single PCI Express slot. It delivers four independent 10/100/1000 Mbps RJ45 connections for servers and data-centre hosts that need high-density copper networking. The 13th-generation BCM5719 controller provides a separate PCI Express function per port, enabling full line-rate throughput across all four links. It targets administrators who consolidate multiple 1 GbE links onto one low-profile card.

Virtualization and power features

Each port supports 17 receive and 16 transmit queues with 17 MSI-X vectors, allowing direct queue assignment to virtual machines through VMware NetQueue and Microsoft VMQ. Energy Efficient Ethernet compliance with IEEE Std 802.3az-2010 reduces power draw during low-link utilisation, while IEEE 802.3ap Clause 73 auto-negotiation optimises link establishment. Wake-on-LAN and hardware timestamp registers for IEEE 1588 or IEEE 802.1AS time synchronisation are also built into the controller.

Check slot height and driver support

Verify that your chassis has a low-profile or full-height bracket opening matching the card bracket, and confirm that a free PCI Express slot with enough electrical lanes is available. Ensure your hypervisor or operating system includes a driver for the BCM5719 family so that virtualization queues and timestamp features activate without extra configuration. Buyers needing fibre uplinks or 10 GbE speeds should select a different adapter.

Questions about this item

Are there moving parts on the BCM95719A1904AC that will need replacement after long-term use?

The card has no fans or other moving components; it relies on passive cooling through the server chassis airflow, so no mechanical wear items are expected.

Which port or bus limit appears first when all four ports run at 1000 Mbps continuously?

Each port can sustain 1000 Mbps full duplex, and the PCI Express host interface provides a separate function per LAN port, so the four 1GbE links are the practical ceiling.

How much power does the adapter draw and how hot does it get when it runs all day in a server?

Energy Efficient Ethernet (IEEE 802.3az-2010) reduces idle power, and the controller is designed for continuous operation in multicore servers with standard chassis airflow.
