Figure 50 NUMA Node and Interrupt Policy parameters
NUMA Node
NUMA (Non Uniform Memory Access) Node is a logical grouping of processors that share common,
directly-linked physical memory. HP ESO recommends CPU NUMA nodes closest to the network
interface I/O.
Interrupt Policy
Network interface interrupt policy settings include All Close CPUs, One Close CPU, or All CPUs. HP
ESO recommends All Close CPUs.
Free NIC for Team
This is a recommendation statement that HP ESO displays when the physical NIC adapter port is
not configured for NIC teaming. HP ESO detects that this NIC adapter does not belong to a NIC
team and recommends to use this adapter to create a NIC team. HP ESO recommends creating
teams of NIC adapters of the same type (for example, NICs that share the same bandwidth or RSS
mode). Teaming of network adapters can provide load balancing, bandwidth aggregation, and
failover capabilities for standard Ethernet NICs. The example in
Figure 53 (page 64) displays this
recommendation statement. If some NICs are configured as a team, the Network page displays
the team participants (Members in Teaming), as shown in
Figure 51 (page 62) . For more information
about NIC teaming, see “NIC teaming” (page 64) .

Port affinity
The Network Port Affinity section of the Network page allows you to select port affinity settings.
The SQL Server uses an application port (usually Port 1433) whose affinity can be set to one or
more CPU NUMA nodes. As with SQL CPU Affinity, this improves performance by directing network
traffic bound to a CPU or group of CPUs used by the SQL Server. Additional ports can also be
added and removed.
To add a specific network port, follow these steps:
