Receive Side Scaling; Tcp/Ip Offloading Options - StarTech.com ST2000SPEXI Instruction Manual

Receive Side Scaling

Enables Receive Side Scaling (RSS). RSS balances receive traffic across multiple CPUs or
CPU cores. This setting has no effect if your system has only one processing unit.
NOTES:
• RSS must be enabled for Intel® I/O Acceleration Technology to function under
Microsoft Windows Server 2003.
• RSS is not supported on some adapters configured to use Virtual Machine Queues
(VMQ). For these adapters VMQ takes precedence over RSS. RSS is disabled.
• Changing this setting can cause a momentary loss of connectivity.
Teaming Notes:
• If RSS is not enabled for all adapters in a team, RSS is disabled for the team.
• If an adapter that does not support RSS is added to a team, RSS is disabled for
the team.
• If a non-Intel adapter is added to a team, its RSS settings must match the Intel
adapters in the team.
• Not all adapters support all RSS queue settings

TCP/IP Offloading Options

IPv4 Checksum Offload
Enables the adapter to verify the IP checksum on received packets and compute
checksum on transmitted packets. Enabling this feature can improve IP performance
and reduce CPU utilization.
NOTE: Changing this setting may cause a momentary loss of connectivity.
TCP Checksum Offload
Enables the adapter to verify the TCP checksum on received packets and compute
checksum on transmitted packets. Enabling this feature can improve TCP performance
and reduce CPU utilization.
This setting can be configured separately for IPv4 and IPv6.
NOTE: Changing this setting may cause a momentary loss of connectivity.
