In a 1,200-server enterprise deploying a hyperconverged private cloud, the Dell Networking S4128T-ON delivers 28 10Gbase-T ports to connect virtualized compute nodes and two QSFP28 100 Gbps uplinks to the spine layer. OS10’s native automation (Ansible, REST) and granular QoS enable sub-10 µs latency, zero-touch provisioning, and seamless firmware updates. Outcome: 30 % faster VM spin-up, 25 % lower ops overhead, and deterministic east-west traffic performance under peak loads.
A cloud hosting provider uses the S4128T-ON as its access/distribution switch to serve 100+ enterprise customers. Each tenant’s 10Gbase-T edge links terminate on the switch while QSFP28 ports uplink to a 400 Gbps spine. Leveraging OS10 EVPN-VXLAN, per-tenant VRFs and MAC-sec encryption, the operator enforces strict isolation and SLA-driven QoS. Outcome: rapid onboarding of new tenants, 99.999 % SLA compliance, and line-rate encryption without performance penalty.
In an AI research lab, 56 GPU-accelerated nodes connect via 10Gbase-T ports on the S4128T-ON, while two QSFP28 uplinks aggregate to 200 Gbps toward the central fabric. OS10’s ML-ready telemetry and buffer tuning optimize all-to-all data exchange during model training. Outcome: 40 % reduction in epoch training time, real-time congestion visibility, and full-rack redundancy with dual PSUs delivering non-stop GPU compute acceleration.
