Generations

Works together

How the arista 7500E 7508E 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.

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 was the significance of the 7508E in cloud infrastructure?

It set industry benchmarks for 40GbE and 100GbE port density and power efficiency, displacing older enterprise chassis across web-scale data halls.

Can a 7508E be upgraded to 7500R line cards?

Yes, swapping the fabric modules to R-series enables 7500R deep-buffer line card operation in the same chassis.
