Hi,
Im setting up a new hyper-v converged network, im looking for a bit of clarification
- I configured DCB (DataCenter Bridge) for ISCSI using the commands showing below. I havent enabled anything on the switches itself (e.g. flow control priority). The NIC has a "OS Controlled" option (see screenshot below), the other option is "Switch Setting". The status on the NIC seems to reflect the QoS policy. Does this mean im achieving the benefits of DCB, or does it need to be configured on the switches?
- Is the bandwidth percentage a minimum, or max? Meaning, if the interface isnt busy, then it will utilized 100%? Likewise, if ISCSI isnt busy, then does it mean that other resources can grab 100% of the bandwidth?
- What exactly is the different between the bandwidth percentage on this QoS class, and the bandwidth config on the vNIC (Set-VMNetworkAdapter -MinimumBandwidthAbsolute/-MinimumBandwidthWeight)?
