About the MMA2P00-AS

The NVIDIA MMA2P00-AS optical transceiver delivers 25 Gigabit Ethernet transmission for enterprise data centers and compute server fabrics. Operating at 850 nanometers over multimode optical cabling, it provides 2.5 times the bandwidth of 10GbE links using the familiar SFP form factor while conserving electrical power in dense rack configurations.

Compatibility

Compatible with NVIDIA Spectrum SN2010, SN2410, SN3420, and SN4410 switches with native SFP28 ports, as well as QSFP-to-SFP QSA adapters in 100GbE ports. It links ConnectX-4 Lx, ConnectX-5, and ConnectX-6 adapters under Cumulus Linux and Linux kernel network drivers.

How to identify a genuine unit

Enclosed in an SFP28 metal casing featuring a black or orange optical extraction latch bail. The manufacturer label identifies the component as MMA2P00-AS with NVIDIA Mellanox branding, individual serial number barcode, and optical safety compliance information.

Buying used

Inspect optical lenses for scratch marks or debris using a precision fiber microscope. Connect the module to an active SFP28 port with RS-FEC configured to verify immediate link synchronization and validate that optical power telemetry values remain within normal factory tolerances.

Works together

How the NVIDIA MMA2P00-AS 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.
