Dell Broadcom 57504 Quad-Port SFP28 Adapter

This new Dell network adapter provides four SFP28 ports for 25 Gbps connectivity in a full-height bracket. It uses the Broadcom 57504 controller and is designed for Dell PowerEdge rack servers.

Suited for Dell PowerEdge upgrades.

The card is validated for a wide range of PowerEdge models including the R640, R650, R740, R750, R760, R840, R860, R940, R960, XE8545, XR11, XR12, XR5610 and XR7620. Buyers with servers from other vendors or older PowerEdge generations not listed should look elsewhere.

Key specification: four 25 Gbps SFP28 ports

The quad-port SFP28 interface is the deciding factor; it delivers four lanes of 25 Gbps Ethernet or storage traffic through a single PCIe slot. Firmware is updated and components are tested before shipment.

Въпроси за този артикул

How do I choose between the 25Gbs quad-port adapter and other port-count options?

This specific model is the quad-port 25Gbs SFP28 version; other port counts would be separate part numbers not covered here.

What does the 25Gbs rating deliver in a live server?

Each of the four SFP28 ports runs at up to 25Gbs, giving four independent 25Gbs links when connected to compatible switches and transceivers.

Which interface standard does the SFP28 connector follow and what does it limit?

The SFP28 interface supports 25Gbs Ethernet per port; the practical ceiling is the 25Gbs lane speed of the SFP28 form factor.
