The network stack consists of the Dell PowerSwitch S5224F-ON, which has 24 x SFP28 ports that can be configured with 10 GbE or 25 GbE and 4 x 100 GbE QSFP28 ports. We configured this switch with 25GbE for the public network and the VMotion network during the tests. We also enabled Jumbo Frame for these two VLANs. When possible, users should consider Jumbo Frame for better performance. When using Jumbo Frame, it is extremely important to ensure that all devices on the same VLAN are configured with Jumbo Frames, or the system will not function properly. In an Oracle RAC deployment, the private interconnect between RAC nodes should be configured with Jumbo Frames. The following table provides an overview of the PowerSwitch.
