Dual 25 GbE SFP28 and 10 GbE RJ45 adapter
This Supermicro SIOM card adds two 25 GbE SFP28 ports and two 10 GbE RJ45 ports to a compatible server. It uses Mellanox ConnectX-4 Lx EN technology for high-speed, low-latency networking. The adapter targets data-centre workloads such as virtualization and cloud computing.
Capacity and headroom
The 25 GbE SFP28 ports provide headroom for heavy east-west traffic and storage replication. The 10 GbE RJ45 ports handle existing copper infrastructure without extra transceivers. Bandwidth runs out when aggregate demand exceeds the PCIe x8 host interface or when cable reach limits the SFP28 optics.
SIOM form factor constraint
This card fits only Supermicro servers that accept a SIOM module. It will not work in standard PCIe slots or in chassis from other vendors. Verify the motherboard SIOM slot before purchase.

Questions about this item
Will this card share a PCIe x8 slot with my existing RAID controller?
The adapter uses a PCIe x8 interface and fits a standard SIOM slot on compatible Supermicro servers.
How do I verify both 25GbE SFP28 and 10GbE RJ45 links are active?
Check the port LEDs on the bracket; each port shows link and activity status for its respective speed.
Does the package include SFP28 transceivers and RJ45 patch cables?
The card ships without transceivers or cables; you must source SFP28 modules and Cat6a or better RJ45 cables separately.
