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

Predefined network profile: 4x10gb or 4x25gb NDC/OCP

  • Figure 72. VxRail nodes with four 10 Gb NDC/OCP ports connected to two ToR switches, and one optional connection to management switch for iDRAC. VxRail nodes with four 10 Gb NDC/OCP ports connected to two ToR switches, and one optional connection to management switch for iDRAC

    In this predefined network profile, VxRail selects all four ports on the NDC/OCP to support VxRail networking instead of two. The same number of cable connections should be made to each switch. This topology provides additional bandwidth over the two-port option, but provides no protection resulting from a failure with the network adapter card.
