In a cloud service provider’s East-West traffic environment, the S4048-ON (48×10GbE SFP+ and 6×40GbE QSFP+) acts as a leaf switch aggregating 48 hyper-converged servers over 10GbE SFP+ with six 40GbE QSFP+ uplinks to spine switches. The result is a non-blocking, low-latency fabric that scales to thousands of VMs while delivering sub-microsecond latency, streamlining multi-tenant operations and accelerating VM migration by 40 %.
A global financial institution consolidates its iSCSI and NVMe-over-TCP storage traffic using the S4048-ON’s 48×10GbE SFP+ ports for server connections and 6×40GbE QSFP+ ports for top-of-rack uplinks to its storage array. This configuration achieves 3 × throughput improvement, reduces storage-access latency by 60 %, and simplifies PSU management with the integrated IO-to-PSU design and single AC power supply.
A multinational corporate campus deploys the S4048-ON as its core switch, terminating 48 building edge switches on 10GbE SFP+ and linking two data halls via 40GbE QSFP+ trunks. The high-density 10GbE ports reduce cabling complexity by 50 %, while the dual-rated AC PSU ensures uninterrupted power. Outcome: unified campus connectivity with 99.999 % availability and 75 % fewer distribution hops.
