About the MMA1T00-HS

The NVIDIA MMA1T00-HS is a 200Gb/s QSFP56 shortwave optical transceiver designed for high-performance computing, AI clusters, and high-throughput storage networks. Utilizing 4 lanes of 50Gb/s PAM4 modulation at 850nm, it provides reach up to 100 meters on OM4 multimode cabling. It delivers low latency and high bandwidth for distributed GPU training and scientific simulations.

Compatibility

Compatible with NVIDIA Quantum QM8700 and QM8790 HDR InfiniBand switches, Spectrum SN4600 Ethernet switches, and ConnectX-6 adapters. It functions reliably in both InfiniBand and Ethernet operating modes, adapting automatically to the host subsystem configuration and software environment.

How to identify a genuine unit

Housed in a standard QSFP56 casing with a blue extraction pull tab and printed NVIDIA Mellanox label. The label contains product code MMA1T00-HS, manufacturing date, and serial number. The transceiver provides comprehensive digital optical monitoring readable via Mellanox Firmware Tools and switch operating systems.

Buying used

Inspect the MPO optical ferrule using an inspection microscope to confirm that all 12 optical channels are clean and scratch-free. Verify that the module locks into the switch cage cleanly and that Mellanox software tools report normal optical levels across all 4 PAM4 transmission lanes.

Works together

How the NVIDIA MMA1T00-HS 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.
