The NVIDIA Spectrum SN2100 is a half-width 1U 100GbE spine and leaf switch delivering 16 ports of 40G/100G QSFP28 in a compact form factor. Providing 3.2 Tbps of non-blocking switching throughput, the SN2100 enables high-density 100G aggregation for storage fabrics, machine learning clusters, and high-frequency trading networks. Side-by-side mounting in 1U allows full physical fabric redundancy with minimal rack footprint, making the SN2100 a highly sought-after model on secondary broker channels.

Works together

How the NVIDIA Spectrum SN2100 connects to servers, storage and the network: 3 ways, with the parts and products 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.

FAQ

Can the 100GbE ports on the SN2100 break out to 25GbE or 10GbE?

Yes, breakout cables allow channelizing each QSFP28 port into 4x 25GbE or 4x 10GbE interfaces, yielding up to 64 ports.

What operating systems are supported on the SN2100?

The switch supports NVIDIA Onyx, Cumulus Linux, and ONIE for open NOS environments like SONiC.
