Adapter Product Features

Intel® PROSet Utility

For easy configuration and management

Plug and play specification

support

Standard

Receive Side Scaling

Multiple Rx queues enable the efficient

distribution of network receive processing

across multiple CPUs in multiprocessor

systems

Direct Cache Access (DCA)

The I/O device activates a pre-fetch en-

gine in the CPU that loads the data into

the CPU cache ahead of time, before use,

eliminating cache misses and reducing

CPU load

Advanced Software Features

Adapter fault tolerance (AFT)

Switch fault tolerance (SFT)

Adaptive load balancing (ALB)

Teaming support
