Generations

Works together

How the arista 7150S-24 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

What is Arista LANZ on the 7150S?

Latency Analyzer (LANZ) provides microsecond-level tracking of buffer congestion, alerting operators before packet drops impact trade execution.

What makes the 7150S latency deterministic?

The cut-through forwarding pipeline executes packet lookups in fixed cycles regardless of packet size or active feature configurations.
