Q2F24A Use Case
Hyperscale Cloud Spine Switching for East-West Traffic Aggregation
In a multi-tenant cloud data center, the Q2F24A-SN2100M 100GbE 8QSFP28 SWITCH PL-1Y functions as a high-capacity spine node, aggregating up to 800 Gbps of east-west traffic from leaf switches over low-latency 100GbE links. This deployment delivers sub-microsecond forwarding, streamlined RESTful provisioning, and industry-leading 99.999% availability under PL-1Y warranty. Outcome: network bottlenecks are reduced by 40%, VM and container spin-up times accelerate by 25%, and capacity scales linearly with demand.
Ultra-Low-Latency Trading Platform Backbone
In a financial trading firm’s colocation environment, the Q2F24A-SN2100M 100GbE 8QSFP28 SWITCH PL-1Y interconnects matching engines, market data feeders, and risk systems across eight 100GbE links. Its deterministic, sub-500 ns latency and cut-through switching ensure price feeds and order messages propagate instantly. Outcome: trade execution windows shrink by 15 microseconds, transaction throughput rises 30%, and regulatory SLAs are met with 100% consistency.
High-Performance Compute Cluster Interconnect for Scientific Simulation
In an HPC research lab, the Q2F24A-SN2100M 100GbE 8QSFP28 SWITCH PL-1Y serves as the central fabric switch linking GPU and CPU compute nodes over 100 GbE. Its wire-speed performance, QoS prioritization, and redundant power supplies under PL-1Y support enable sustained 800 Gbps bidirectional links without packet loss. Outcome: large-scale simulations complete 30% faster, cluster utilization climbs above 95%, and maintenance windows shrink by 50%.
