#VCP #Network #Concept Allows you to shape the bandwidth across the different products of vSphere. You can specify different bandwidths for services. It can only be activated on a [[vSphere - Distributed Switch.md]]. Useful for QoS of different traffics like vSAN, vMotion, Management. It is either configured on an entire vDS or on the physical adapter which carries VM traffic NIOC divides traffic into different network pools. ## Requirements/Limitations - vDS switch with version 6.0 or higher - VMs cannot use SR-IOV - bandwith reserved cannot exceed 75% or the bandwidth provided by the physical network adapter ## System traffic here we can configure priotites/shares for each Network system traffic, which includes: - Management network - [[Technicallycorrect/Concepts/VCP/vSphere - Fault Tolerance.md|vSphere - Fault Tolerance]] - NFS - vMotion - vSphere replication - vSphere data protection backup - Virtual Machine traffic ### Shares is a value from 1 to 100, effectively the priority of a system traffic compared to the other types. ### Reservation the minimum bandwidth in Mbps that is guaranteed/reserved for certain traffic, when not used by the configured system traffic it can be used by other system traffics. This is not the case for ISCSI traffic, for ISCSI traffic the vDS does not impose on the configured reservation. ### Limit maximum bandwidth a system traffic type can consume on a single physical adapter ### Network Resource Pools VMs can be assigned to a network resource pool and consume the resources based on the configured capacity. ## 🔗Resources
