Lenovo ThinkSystem Broadcom 57508 100GbE QSFP56 2-Port PCIe 4 Ethernet Adapter

For servers that need 100GbE links, the Lenovo ThinkSystem Broadcom 57508 100GbE QSFP56 2-Port PCIe 4 Ethernet Adapter, part number 4XC7A08297, provides two QSFP56 ports driven by a Broadcom 57508 controller. The PCIe 4 designation in the title tells you it is built for Gen4 slots.

Two ports at this speed are typically used for redundant uplinks to a pair of switches or for storage and cluster traffic that needs high throughput. The cages are QSFP56, so modules and cables must be matched to that form factor and to your switch ports.

As a ThinkSystem-branded Broadcom part, it is the choice when your server was specified with the Broadcom controller. Other 100GbE adapters from different vendors may fit the same slot but bring different drivers and firmware.

The 4XC7A08297 is offered new and refurbished. Both conditions have a warranty choice of 1 year or 3 years. No used offer is listed. To request pricing, send the quantity and the server model so we can confirm fit.
