Intel I/O Acceleration Technology (Intel I/OAT) is a suite of features that improves data acceleration
across the platform, from networking devices to the chipset and processors, which helps to improve
system performance and application response times. The different features include Intel® QuickData,
Direct Cache Access (DCA), MSI-X, Low-Latency Interrupts, Receive Side Scaling (RSS), and others.

Virtual Machine Device Queues (VMDq) reduces I/O impact on the hypervisor in a virtualized server by
performing data sorting and coalescing in the network silicon. VMDq technology makes use of multiple
queues in the network controller. With VMDq, as data packets enter the network adapter, they are sorted,
and packets to the same destination (or virtual machine) are grouped together in a single queue. The
packets are then sent to the hypervisor, which directs them to their respective virtual machines. Relieving
the hypervisor of packet filtering and sorting improves overall CPU usage and throughput levels.

The expansion card has iSCSI support for proven native OS and VMM iSCSI initiators. Historically,
CRC32C computation has degraded system performance, but now with the CRC instruction set included
in the latest Intel Xeon processors, CRC validation is possible with minimal impact to network throughput
while delivering data integrity.
