J9821A Use Case
High-Density 100GbE Aggregation in Hyperscale Data Centers
Scenario: A hyperscale data center requires multi-petabit east-west traffic aggregation with ultra-low latency. The J9821A-5406R ZL2 SWITCH NO PS PL=35 delivers 48 QSFP28 100GbE ports in a 2U form factor and a ZL2 switching fabric, enabling a 10Tbps per chassis spine-leaf topology. Benefit: Achieves sub-2µs latency, reduces switch count by 40%, and delivers scalable, power-optimized 35W QSFP28 port performance to accommodate explosive traffic growth.
Enterprise Campus Core Network Consolidation
Scenario: A large enterprise campus needs to consolidate multiple distribution switches into a single core layer to simplify management and reduce OPEX. The J9821A-5406R’s 48-port 100GbE density and modular fabric cards streamline device count, while its 35W per port power profile lowers cooling requirements. Benefit: Cuts rack space by 50%, reduces power consumption by 30%, and centralizes policy enforcement for faster, more reliable campus connectivity.
Service Provider Edge & Cloud On-Ramp
Scenario: A service provider requires seamless aggregation of customer VLANs and high-speed cloud on-ramp connectivity at the network edge. Leveraging the J9821A-5406R’s programmable ZL2 architecture and 100GbE QSFP28 interfaces, they implement advanced QoS, EVPN-VXLAN, and segment routing. Benefit: Delivers deterministic SLAs with 10Tbps throughput, simplifies multi-tenant segmentation, and accelerates cloud access while optimizing power and footprint.
