What is the switching capacity and port configuration of S5448F-ON?

The S5448F-ON provides 16Tbps full-duplex switching capacity and 2.6Bpps forwarding rate. It includes 48x multi-rate 100GbE SFP56-DD ports (10/25/50/100GbE), 8x multi-rate 400GbE QSFP56-DD ports (10/25/40/50/100/200/400GbE), and 2x 10GbE SFP+ ports in a compact 1RU form factor for high-density aggregation.

Does the S5448F-ON support open networking and which OS options?

Yes, it supports ONIE for disaggregated networking. Compatible OS include Dell SmartFabric OS10, Enterprise SONiC Distribution by Dell Technologies, and select third-party network operating systems, enabling flexible deployment in multi-vendor environments.

What DCB features make it suitable for storage deployments?

It supports Priority Flow Control (PFC), Data Center Bridging Exchange (DCBX), and Enhanced Transmission Selection (ETS) for lossless Ethernet. These enable converged iSCSI and FCoE transactions over 100/400GbE with zero packet loss in DCB environments.

What are the key performance metrics like latency and routing scale?

Sub-1135ns latency, 82MB packet buffer, up to 256K MAC addresses, 875K IPv4 routes (ALPM), 310K IPv6 routes, 4K VLANs, and 16K multicast routes. Intel 8-core CPU at 2.2GHz with 32GB DDR4 ECC ensures robust L2/L3 processing.

What redundancy and airflow options are available?

Features redundant hot-swappable 1600W AC PSUs (x2), 6x fans with N+1 redundancy, and dual airflow directions: IO-to-PSU or PSU-to-IO for hot/cold aisle data centers. Supports PTP/1588 timing and Sync-E.

Is VLT supported for multipath redundancy?

Yes, L2 multipath via Virtual Link Trunking (VLT) and Routed VLT. LAG load balancing uses L2/IPv4/IPv6 headers, with 64 MSTP instances for resilient topologies in aggregation layers.

Product overview

The Dell PowerSwitch S5448F-ON is a next-generation 1RU fixed aggregation switch designed for high-density data center environments. It features 48 ports of 100GbE SFP56-DD (supporting 10/25/50/100GbE) and 8 ports of 400GbE QSFP56-DD (supporting 10/25/40/50/100/200/400GbE), plus 2x 10GbE SFP+ management ports, delivering 16Tbps full-duplex switching capacity and 2.6Bpps forwarding rate with sub-1135ns latency. Powered by Intel Denverton C3758 8-core CPU at 2.2GHz with 32GB DDR4 ECC memory, it supports ONIE for flexible OS choices like Dell SmartFabric OS10, Enterprise SONiC, or third-party NOS. Key benefits include non-blocking line-rate performance, L2/L3 features (OSPF, BGP, 875K IPv4 routes), DCB with PFC/DCBX/ETS for lossless iSCSI/FCoE, Virtual Link Trunking (VLT) for multipath, and redundant hot-swap PSUs/fans. Ideal for ToR access, spine aggregation, HPC clusters, cloud providers, and web-scale deployments requiring ultra-low latency and high bandwidth density.
