Lenovo ThinkSystem Broadcom 57508 100GbE QSFP56 2-Port OCP Ethernet Adapter

High-speed uplinks in an OCP slot are the purpose of the Lenovo ThinkSystem Broadcom 57508 100GbE QSFP56 2-Port OCP Ethernet Adapter, part number 4XC7A08243. It carries two QSFP56 ports at 100GbE, controlled by a Broadcom 57508.

The OCP 3.0 form means the module installs in a dedicated server slot and does not use a PCIe slot, so it is a fit only where the chassis provides that slot. The PCIe-form card with the same controller is sold under a separate part number.

Two 100GbE ports usually serve redundant uplinks to a pair of switches, or a combination of storage and compute traffic. QSFP56 cages need compatible modules or cables, sourced separately and matched to your switch ports and distances.

When replacing a card, match the controller and the form factor as well as the speed. Those two details decide whether drivers and slots line up.

This part is available new, refurbished and used. New and refurbished modules have 1 year or 3 years of warranty, and used modules have 90 days. Request pricing with your quantity and server model.
