SETTING UP SCALABLE NETWORKING PACK (SNP)

Microsoft Windows Server 2003 Scalable Networking Pack (SNP) is a module that improves
network throughputs by offloading the packet processing to the specific network adapter.
SNP supports the following operating systems:
– Windows Server 2003 x64 Editions
– Windows Server 2003
SNP has the following features:
TCP Chimney Offload

TCP Chimney Offload feature can reduce the CPU overhead by offloading networking
tasks such as packet division and packet reconstruction to the network adapter.
Receive-side Scaling

Receive-side Scaling enables packet receive-processing to scale with the number of
available CPUs. The network processing load is balanced between the CPUs.
NetDMA

Normally, the memory transfer operation of network data is performed by the CPU. Using
DMA (Direct Memory Access) of the network adapter for that process can reduce CPU
utilization.
IMPORTANT: The onboard network adapter and optional lan board
(N8403-017/020/021/022) do not support TCP Chimney Offload
feature.
