Works together

How the arista 7150S-52 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

Why is hardware NAT important on the 7150S?

Hardware NAT allows algorithmic trading servers to translate private IP addresses at wire speed without adding software router latency.

Can the 7150S-52 ports run at 1GbE speeds?

Yes, all 52 ports support standard 1GbE SFP transceivers with sub-microsecond latency.
