NVIDIA Spectrum SN2010
The NVIDIA Spectrum SN2010 is a half-width 1U top-of-rack Ethernet switch engineered for hyperconverged infrastructure, storage clustering, and space-constrained datacenters. Providing 18 ports of 10G/25G SFP28 and 4 ports of 40G/100G QSFP28, the SN2010 allows two switches to be mounted side-by-side in a single 1U rack slot for complete high-availability switching redundancy. Operating with Onyx, Cumulus Linux, or SONiC, the SN2010 is traded extensively by secondary brokers for Nutanix and VMware vSAN deployments.

Works together
How the NVIDIA Spectrum SN2010 connects to servers, storage and the network: 3 ways, with the parts and products on each path.
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.

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.
