C VxRail network adapter traffic optimization
VxRail optimizes network traffic by splitting traffic across rNDC uplinks and by using NIOC shares. Based on
traffic type, uplinks are configured as active or standby, and NIOC shares are used to allocate network
bandwidth. Uplink load balancing and NIOC shares are automatically configured by VxRail.
