Data plane networking switches carry all OpenShift cluster ingress/egress traffic, all internal traffic, and all storage traffic. Dell EMC engineers chose base-line switches for the Ready Architecture design to handle anticipated maximum data flow rates over a 25 GbE connection. For an economy of scale or to provide a longer switch lifetime, you might decide to use 25 GbE switches or 100 GbE switches to provision the network infrastructure.
The Dell EMC Networking S5248F-ON switch is a multi-rate ToR data center switch that delivers the architectural agility and flexibility that is needed to deploy software-defined infrastructure so that you can easily deploy cost-effective, high-capacity network fabrics. The S5248F-ON switch provides optimum flexibility and cost-effectiveness for demanding compute and storage traffic environments. This switch features 48 x 25 GbE SFP28 ports, 4 x 100 GbE QSFP28 ports, and 2 x 100 GbE QFSP28-DD ports.
The S5248F-ON switch also supports Open Network Install Environment (ONIE) for zero-touch installation of network operating systems. Line-rate performance delivered by non-blocking switch fabrics is 2.0 Tbps on the S5248F-ON switch.
The Dell EMC Networking S5232F-ON switch is a suitable ToR choice that supports a configuration in a rack of up to 30 nodes. The S5232F-ON switch is also suitable for building out a multirack cluster infrastructure.
The S5232F-ON switch enables you to build a high-performance, cost-efficient data center leaf/spine fabric with a switch featuring 32 x 100 GbE QSFP28 ports. The S5232F-ON switch also supports ONIE for zero-touch installation of network operating systems. Non-blocking switch fabrics provide a line-rate performance of 3.2 Tbps S5232F-ON switches.
