New user-configurable properties available in Windows Server 2019 are
described in the following sections:
Max Queue Pairs (L2) Per VPort
VMQ and VMMQ Default Accelerations
Max Queue Pairs (L2) Per VPort
, Windows 2019 (and Windows
2016) introduced a new user-configurable parameter,
Max Queue Pairs (L2) per
VPort
. This parameter permits greater control of resource distribution by defining
the maximum quantity of queue pairs that can be assigned to the following:
VPort-Default VPort
PF Non-Default VPort (VMQ/VMMQ)
SR-IOV Non-Default VPort (VF)
1
The default value of the
Max Queue Pairs (L2) per VPort
parameter is set to
Auto
, which is one of the following:
Max Queue Pairs for Default vPort = 8
Max Queue Pairs for Non-Default vPort = 4
If you select a value less than 8, then:
Max Queue Pairs for Default vPort = 8
Max Queue Pairs for Non-Default vPort = value
If you select a value greater than 8, then:
Max Queue Pairs for Default vPort = value
Max Queue Pairs for Non-Default vPort = value

Network Direct Technology
