FAQ
What type of servers is this adapter compatible with?
This HPE adapter is designed for servers supporting OCP3 form factor cards. It requires a PCI Express 2.0 slot and is optimized for server environments from major vendors. The OCP3 bracket height ensures proper fitment in compatible server chassis, making it suitable for rack-mounted and blade server deployments where standard OCP3 slots are available.
How many network ports does this adapter provide?
The adapter delivers four independent Gigabit Ethernet ports through RJ-45 connectors. All four ports operate simultaneously at 1 Gbit/s data transfer rates, providing network density for servers requiring multiple network segments or connections. Each port supports full-duplex operation for maximum throughput in demanding server applications.
What is the maximum data transfer rate per port?
Each of the four RJ-45 ports supports 1 Gbit/s (1000 Mbps) data transfer rates. The PCI Express 2.0 host interface provides sufficient bandwidth to handle aggregate traffic from all four ports without bottlenecking. This enables the adapter to deliver up to 4 Gbit/s of total network throughput when all ports are active simultaneously.
What type of cabling does this adapter support?
The adapter supports standard twisted pair cabling, specifically Category 5e, Category 6, or higher Ethernet cables. It uses RJ-45 connectors and supports transmission distances up to 100 meters per the Ethernet standard. This makes it compatible with existing copper network infrastructure without requiring specialized fiber optic cabling or transceivers.
What is the OCP3 form factor?
OCP3 is a standardized form factor for network interface cards in servers, specifying physical dimensions and bracket height for compatibility with server chassis. This adapter's OCP3 design ensures it fits properly in servers designed for this form factor, providing reliable mechanical mounting and proper alignment with server backplane connectors. The compact profile maximizes rack density while maintaining full network functionality.
Does this adapter support virtualization environments?
Yes, the Broadcom BCM5719 chipset includes features optimized for virtualization, including support for virtual machine queue technology and network traffic management. This makes the adapter suitable for hypervisor hosts running VMware, Hyper-V, or other virtualization platforms where network performance and segmentation are critical for virtual machine operation and management traffic isolation.
