Supermicro AOC-MH25G-M2S2TM Dual 25GbE SFP28 & Dual 10GbE RJ45 Adapter

Dual 25 GbE & 10 GbE SIOM Adapter

The Supermicro AOC-MH25G-M2S2TM is a Super I/O Module (SIOM) that adds two 25 GbE SFP28 ports and two 10 GbE RJ45 ports to compatible Supermicro servers. It uses a Mellanox ConnectX-4 Lx EN controller for the 25 GbE links and an Intel X550-AT2 controller for the 10GBase-T links, giving a single slot mixed-speed connectivity.

Suited for mixed-speed server fabrics.

This card suits administrators who need both 25 GbE uplinks and 10 GbE RJ45 connections in one SIOM slot, especially in virtualised clusters using SR-IOV and RDMA over Converged Ethernet on the 25 GbE side. Buyers who only require 10 GbE RJ45 or only 25 GbE SFP28 should look at single-controller adapters that match their exact port requirement.

Four ports with hardware offload headroom

The dual 25 GbE ports handle 25, 10 and 1 GbE speeds with 9.6 KB jumbo frames, hardware offloads for NVGRE, VXLAN and GENEVE, and low-latency RoCE. The dual 10 GbE RJ45 ports provide 10GBase-T connectivity with NC-SI remote management. Both controllers support IEEE 802.3ad link aggregation, 802.1Q VLAN tagging and 1588v2 precision timing.
