What are the port configurations on Dell 210-ALTG S4128F-ON?

The S4128F-ON features 28x 10GbE SFP+ ports for server/edge connections and 2x 100GbE QSFP28 ports for uplinks. This supports breakout cables for 4x25GbE flexibility, delivering non-blocking throughput ideal for 10/40/100GbE data center fabrics with low latency under 1us.

Does it support Layer 3 routing features?

Yes, as a Layer 3 switch, it handles OSPF, BGP, VRF, and EVPN for dynamic routing. Combined with VXLAN, it enables overlay networks for multi-tenant clouds, reducing complexity in large-scale deployments while maintaining wire-speed performance.

What power and cooling options are available?

Equipped with dual hot-swappable 550W AC PSUs for 1+1 redundancy and 4x hot-swap fan modules in I/O-to-PSU airflow. Max power draw is ~500W, with 1500 BTU/h heat dissipation, ensuring reliability in 24/7 data center operations.

Is it compatible with virtualization platforms?

Fully integrates with VMware NSX, Microsoft Hyper-V, and KVM via OS10 NOS. Supports SR-IOV, VTEP for VXLAN, and OpenStack Neutron, allowing seamless network virtualization and orchestration in private/hybrid cloud environments.

What management interfaces does it offer?

OS10 provides CLI, web GUI, RESTCONF/YANG APIs, SNMPv3, and sFlow for monitoring. Centralized management via Dell OpenManage Network Director enables zero-touch provisioning and analytics for large fabrics.

What airflow directions are supported?

Standard I/O Panel to PSU airflow for front-to-back cooling in most racks. TAA-compliant variants offer reverse PSU-to-I/O, ensuring compatibility with diverse data center hot/cold aisle containment strategies.
