juniper QFX Series QFX10016
The Juniper QFX10016 is a 16-slot 21U modular core and spine chassis switch delivering up to 96 Tbps of switching throughput. Designed for massive cloud fabrics and carrier datacenter backbones, the QFX10016 houses sixteen line card slots, dual redundant routing engines, and six switch fabric modules. Built on deep-buffer Q5 ASICs, the QFX10016 handles dense multi-tenant virtualization, massive route scale, and continuous wire-speed 100G and 400G traffic without packet drops.

Works together
How the juniper QFX Series QFX10016 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.
