Works together

How the arista 7050X 7050CX3-32S 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

How does the 7050CX3 compare to the 7060CX?

The 7050CX3 is built on Trident 3 silicon with larger routing tables and enterprise telemetry, while the 7060CX is built on Tomahawk silicon optimized for maximum port density.

Can the 100G ports be broken out into 4x 25G?

Yes, each QSFP28 port supports 4x 25G or 4x 10G breakout connections.
