Juniper Networks QFX5230-64CD switch is a high-radix class switch, dedicated for high-bandwidth network switching devices supporting up to 64 × 400GbE, 128 × 200GbE, 256 × 100GbE, 64 × 40GbE, 256 × 25GbE, 256 × 10GbE ports in 2 U form factor. This makes the QFX5230-64CD optimal for AI data center deployments and spine and super-spine roles within IP and Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) fabrics. The additional Remote Direct Memory Access over Converged Ethernet (RoCEv2) capabilities of the QFX5230-64CD support IP storage deployments where instead of relying on deep buffer switching, the QoS mechanisms such as priority-based flow control-distributed services code point (PFC-DSCP) and explicit congestion notification (ECN) deliver high performance for the storage workloads. Support for ZR/ZR-M optics makes it suitable for edge and data center interconnect (DCI) use cases.
