Product overview
Juniper lists QFX5100-48S-3AFI as a QFX5100-48S 48x10GbE SFP+ 6x40GbE QSFP+ data centre Switch. Switches are chosen on port mix and uplink capacity rather than headline throughput. This one is 48x10GbE. Tell us what it is aggregating and we will confirm the uplinks and optics you will also need.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

Specifying a system, not just the part?
Multi-node training is bounded by the fabric between the nodes, so the switch is specified with the cluster rather than after it.
