Pre-defined network profile: 2x10gb or 2x25gb from a single NDC/OCP
Predefined network profile: 4x10gb or 4x25gb NDC/OCP
Predefined network profile: 2 x 10/25 GB NDC/OCP and 2 x 10/25 GB PCIe
Custom option: Any NDC/OCP ports paired with PCIe ports
Custom option: Two NDC/OCP ports paired with PCIe ports other than the first slot
Custom option: PCIe ports only
Custom option: Six ports
Custom option: Eight ports
Custom option: Eight ports connected to four Ethernet switches

Custom option: Eight ports

Custom option: Eight ports

  • For workload use cases with extreme availability, scalability, and performance requirements, up to eight ports can be selected to support VxRail networking. This option is advantageous if it is desirable to have resource-intense networks such as vSAN or VMware vSphere vMotion have dedicated Ethernet ports. This option can also be useful if you want VxRail to configure a guest network with dedicated Ethernet ports as part of the initial build process.
