The Arista 7508 is an 8-slot modular datacenter chassis switch delivering up to 11.52 Tbps of switching bandwidth in an 11U frame. Providing eight payload line card slots, dual supervisors, and six fabric modules, the 7508 served as the benchmark modular 10G/40G spine switch for large-scale cloud providers and enterprise datacenters during the early 2010s.

Generations

Works together

How the arista 7500 7508 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.
