Next generation cloud service applications not only consume more data, it requires service providers to build more flexible, agile and scalable networks to meet the increasing demands of their customers. 
The evolution to 800G will provide data centers with the capability to meet capacity and utilization demands of AI application. The S9321-64E 800G data center switch will provide data centers with a rich set of features such as advance adaptive routing, powerful load balancing and end-to-end congestion control to address the high performance networking demands of AI/ML network to minimize the job completion time (JCT).

  • Hardware-based encapsulation includes Multiprotocol Label Switching(MPLS), and generic routing encapsulation(GRE)
  • Enhanced buffering and traffic management with Priority-based Flow Control (PFC) and Enhanced Transmission Selection(ETS)
  • 5nm process technology delivers unmatched power efficiency and performance
  • Hardware-based link failover  Improves network resiliency and reduces JCT
  • Advanced adaptive routing and end-to-end congestion control capabilities
  • Designed to handle the large, low entropy flows typical of AI/ML  workloads
