support more than 64 processors. Beginning with Windows 2012, RSS can support more than 64
processors.

Modern network drivers are configured to use RSS through settings found in the Windows Device
Manager, in the Advanced Properties of the network interface. Depending on the driver versions
and OS versions, HP ESO might not support some of the RSS features. Contact HP support for
details.

HP ESO recommends that RSS be enabled as necessary. The following parameters of every Network
Interface will have corresponding RSS recommended settings:

Base Processor — The first logical CPU number to be used for RSS.

RSS status — Disable or enable NIC adapter RSS function.

Max RSS Processors — The maximum number of logical processors to be used for RSS of the
network interface.

RSS Rings or RSS Queues — The maximum number of CPUs a NIC can support for RSS. The
number of RSS CPUs on a system would be capped by the MaxNumRssCpus registry key or
the RSS ring NIC property setting, whichever is the lowest.

Queues can be associated with specific processor cores to distribute the workload and prevent
data traffic processing from overwhelming a single core.

NOTE:

HP ESO detects NIC adapter RSS support when the driver has RSS and RSS Ring or RSS

Queue properties enabled.

NIC teaming

NIC teaming, also known as Load Balancing/Failover (LBFO), allows multiple network adapters
on a computer to be placed into a team for the purpose of providing:

Bandwidth aggregation

Traffic failover to maintain connectivity in the event of a network component failure

With configuration of a NIC team, one or more physical NICs are connected into the NIC teaming
solution core, which then presents to the operating system one or more virtual adapters. These
virtual adapters are presented as team interfaces or team NICs (tNICs). NIC teaming in a native
