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 suite of features includes the following items:
- Intel QuickData Technology: Provides the Direct Memory Access (DMA) engine, which moves data by using the chipset instead of the processor.
- MSI-X: Minimizes the impact of I/O interrupts by load-balancing interrupts across multiple processor cores.
- Low-Latency Interrupts: Allows the adapter to bypass the automatic moderation of time intervals between the interrupts (based on the sensitivity of the incoming data).
- Receive Side Scaling (RSS): Directs the interrupts to a specific processor core based on the application’s address.
Virtual Machine Device Queues (VMDq) reduce the I/O impact on the Hypervisor in a virtualized server by performing data sorting and coalescing in the network silicon. VMDq technology uses multiple queues in the network controller. As data packets enter the network adapter, they are sorted, and packets traveling to the same destination (or virtual machine) are grouped 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 processor usage and throughput levels.
Single Root I/O Virtualization (SR-IOV) is a method where the adapter and its resources are virtualized so that virtual machine guest can separately configure and access the virtualized resources without impacting the use of the same resources by other virtual machines.
