HPE P08449B21 1Gb 4-port BASE-T I350-T4 OCP3 network card

Four-port 1Gb BASE-T OCP3 adapter

The HPE P08449B21 adds four copper Ethernet ports to a Gen10 Plus server through the OCP 3.0 mezzanine slot. It targets administrators who need additional 1 Gb/s links for management, storage or workload networks without occupying a PCIe riser.

Sustained throughput with CPU offload

The Intel I350-T4 controller handles checksum, segmentation and tunneling offloads in hardware, keeping host CPU utilisation low during continuous traffic. RDMA support further reduces interrupt overhead for latency-sensitive applications running at line rate across all four ports.

Signed-firmware root of trust

Digitally signed firmware is verified against a hardware root of trust at every boot, preventing unauthorised code from loading on the adapter. The low-profile OCP 3.0 form factor secures with a thumbscrew, allowing tool-less installation and removal during routine server maintenance.
