l 8 and 16 queues are supported on the Intel® 82598-based and 82599-based
adapters.
NOTES:
l The 8 and 16 queues are only available when PROSet for
Windows Device Manager is installed. If PROSet is not
installed, only 4 queues are available.
l Using 8 or more queues will require the system to reboot.
NOTE: Not all settings are available on all adapters.
LAN RSS and Teaming
l If RSS is not enabled for all adapters in a team, RSS will be disabled for the team.
l If an adapter that does not support RSS is added to a team, RSS will be disabled for the team.
l If you create a multi-vendor team, you must manually verify that the RSS settings for all adapters in the
team are the same.
FCoE RSS
If FCoE is installed, FCoE RSS is enabled and applies to FCoE receive processing that is shared across
processor cores.
FCoE RSS Configuration
If your adapter supports FCoE RSS, the following configuration settings can be viewed and changed on the
base driver Advanced Performance tab:
l FCoE NUMA Node Count. This setting specifies the number of consecutive NUMA Nodes where
the allocated FCoE queues will be evenly distributed.
l FCoE Starting NUMA Node. This setting specifies the NUMA node representing the first node within
the FCoE NUMA Node Count.
l FCoE Starting Core Offset. This setting specifies the offset to the first NUMA Node CPU core that
will be assigned to FCoE queue.
l FCoE Port NUMA Node. This setting is an indication from the platform of the optimal closest NUMA
Node to the physical port, if available. This setting is read-only and cannot be configured.
Performance Tuning
The Intel Network Controller provides a new set of advanced FCoE performance tuning options. These
options will direct how FCoE transmit/receive queues are allocated in NUMA platforms. Specifically, they
direct what target set of NUMA node CPUs can be selected from to assign individual queue affinity. Selecting
a specific CPU has two main effects:
l It sets the desired interrupt location for processing queue packet indications.
l It sets the relative locality of the queue to available memory.
As indicated, these are intended as advanced tuning options for those platform managers attempting to
maximize system performance. They are generally expected to be used to maximize performance for multi-
