The Juniper QFX5100-96S is a high-density 2U datacenter top-of-rack and end-of-row switch providing 96 fixed 10GbE SFP+ ports and 8 fixed 40GbE QSFP+ uplinks. Offering 2.56 Tbps of throughput in a single compact chassis, the QFX5100-96S was designed to consolidate cabling across densely populated server racks without requiring multiple physical switches. Secondary hardware traders value the 96S model for high-port-count virtualization farms and high-density enterprise distribution layers.

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.
