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.
