HPE 100Gbps Dual Port Adapter

The HPE P11335-B21 is a dual-port 100Gbps network interface card built for PCI-Express slots. It uses 870QSFP28 connectivity to deliver high bandwidth and low latency for demanding server workloads.

Suited for datacentre

This adapter targets datacentre servers and high-performance computing clusters that require 100Gbps links. It is not intended for desktop PCs, workstations or any system lacking a compatible PCI-Express slot and QSFP28 cabling infrastructure.

PCI-Express interface with dual 870QSFP28 ports

The card installs into a PCI-Express slot and presents two 870QSFP28 ports rated at 100Gbps each. Compatibility depends on the host server supporting this form factor, speed and optical or direct-attach cabling.

Questions about this item

Will the dual QSFP28 ports on the 870QSFP28 adapter need module replacements over time?

The 870QSFP28 adapter uses two QSFP28 ports that accept hot-pluggable transceivers; modules can be swapped individually without replacing the card.

What limits sustained throughput on the P11335-B21 when running at 100Gbps per port?

Each port is rated for 100Gbps and the PCI-Express interface carries the combined load; the bus width and generation set the practical ceiling.

How much heat does the 870QSFP28 generate during continuous all-day operation?

The adapter is a passive PCI-Express card with no onboard fan; it relies on server chassis airflow to dissipate heat from the dual 100Gbps ports.
