About the MMA1L10-CR

The NVIDIA MMA1L10-CR optical transceiver provides 100 Gigabit Ethernet connectivity for cloud data centers and enterprise core networks. Operating across four optical channels at 850 nanometers on multimode fibre, it provides short-reach inter-switch connectivity and server uplinks with low power consumption and high signal reliability.

Compatibility

Compatible with NVIDIA Spectrum SN2000, SN3000, and SN4000 Series Ethernet switches. It plugs into QSFP28 ports and supports interoperability with ConnectX-4, ConnectX-5, and ConnectX-6 100GbE network adapters running under Onyx or Cumulus Linux network operating systems.

How to identify a genuine unit

Enclosed in a standard QSFP28 metallic case featuring a beige or black optical pull tab extraction handle. The top product label displays NVIDIA Mellanox branding, model designation MMA1L10-CR, serial number barcode, and optical safety compliance information.

Buying used

Inspect the internal MPO optical guide pins and ferrule face with a fiber microscope to verify that no dust or scratches exist on any of the fiber cores. Test in an active Spectrum switch port to confirm that all four optical channels synchronize and report balanced optical power levels.

Works together

How the NVIDIA MMA1L10-CR 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.

Storage

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.
