Improve network application responsiveness with more efficient data movement and reduced system overhead. Today's multi-port GbE and 10GbE network adapters deliver enormous data flows that require advanced server I/O subsystems to avoid performance bottlenecks.

Intel® I/O Acceleration Technology (Intel® I/OAT), a component of Intel® Virtualization Technology for Connectivity, improves data flow across the platform to enhance system performance.

I/O acceleration for consolidated workloads
Server consolidation requires large numbers of virtual machines (VMs) per physical server. Intel I/OAT helps ensure that the resulting data traffic doesn't overwhelm server I/O:

Throughput: Improves CPU-network interface integration for better memory-copy performance.
 
Scalability: Increases control over interrupt processing, including prioritization and resource allocation.

Efficiency: Provides an alternative to interrupt and system-to-user memory copy operations for each packet.

Together, these capabilities work in concert to address data-flow bottlenecks across the platform such as those caused by Video recording and archiving traffic.
