introduced new data center switches based on the most advanced Broadcom Tomahawk 5 silicon for 800GE:
- 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. The switch is designed 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.
- QFX5240 800GbE switch (64 port 800GbE) is a next-generation, fixed-configuration platform designed for spine, leaf, and border switch roles. The switch provides flexible, cost-effective, high-density 800GbE, 400GbE, 100GbE, and 50GbE interfaces for intra-IP fabric connectivity as well as higher density 200/400GbE NIC connectivity for AI/ML use cases. It’s 51.2Tbps unidirectional throughput meets the bandwidth requirement of AI/ML workloads and storage systems with latency in the range of 700-750ns. Remote Direct Memory Access (RDMA) is the de-facto data transfer technology used in AI/ML workloads, and it uses Remote Direct Memory Access over Converged Ethernet v2 (ROCEv2) for transport at the network layer.
Both platforms offer Juniper Apstra intent-based networking, which delivers full Day 0 through Day 2+ capabilities for IP/EVPN fabrics with closed-loop assurance in the data center. Apstra is a fabric management solution that empowers organizations to automate and manage their networks across virtually any data center design, vendor, and topology, making private data center as easy as cloud. Apstra provides full Day 2+ operations assurance with multiple built-in intent-based analytics probes to assure your network is running as designed.
