NPAR NPAR divides network adapter ports into multiple partitions based on the number of PFs. Each port on the ETH681i network adapter can be divided into eight partitions and a network adapter can be divided into 16 partitions. SR-IOV Both ports on the network adapter support SR-IOV. - Page 43 The network adapter supports 0 to 96 VFs for each PF. VLAN (802.1Q VLAN) Each port on the network adapter supports a maximum of 4094 VLANs. A network adapter only transmits packets, and does not tag or untag packets. The VLAN ID is in the range of 1 to 4094 and is assigned by the operating system.
- Page 44 direction. If a large amount of traffic goes to the same destination address, the traffic will be sent by the same physical NIC. • Hyper-V port mode—Transmits data out of different physical NICs bound to virtual NICs on a per-virtual NIC basis, instead of a per-VM basis. This mode has higher efficiency if compared with the address hash mode.
