About the AOC-S40G-I2Q

Supermicro AOC-S40G-i2Q: Standard LP 2-port 40GbE controller, Intel Fortville XL710 is sold by Supermicro under product ID AOC-S40G-i2Q. It is a network adapter in the Supermicro option range and appears in the ordering or configuration tables of the vendor documents cited in the sources. The product ID is the number brokers and buyers search for, so match it exactly rather than by capacity or description alone.

Compatibility

The Supermicro documents cited in the sources list AOC-S40G-i2Q as an option for Supermicro SYS-1029U-TN10RT, Supermicro SYS-1029U-TR4, Supermicro SYS-2029BT-HNR, Supermicro SYS-2029U-TN24R4T, Supermicro SYS-2029U-TR4, Supermicro SYS-4029GP-TRT, Supermicro SYS-5039MS-H8TRF. That listing is the only compatibility claim recorded here: the part is not assumed to fit other generations or other product lines of the same brand. Firmware, software, slot, backplane and controller requirements are set out in the vendor documentation for the specific product, and the vendor's compatibility tool should be checked before ordering a second-hand unit.

Buying used

Check the product ID on the label, the port count and speed, and that the bracket suits the chassis. Optical ports need compatible transceivers or cables, which are usually sold separately. Ask the seller for photos of the part number label, confirm the return terms, and test the part in a running system before accepting it. Prices vary with condition, so compare several listings for the exact product ID.

Works together

How the Supermicro AOC-S40G-I2Q connects to servers, storage and the network: 3 ways, with the hardware on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.
