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.

Figure 53 (page 64) shows the Network page view of RSS parameter optimization

recommendations.

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
