Intel Ethernet Converged Network Adapter X540-T2

Intel® Ethernet Converged Network Adapter X540-T2 designed with Advanced Technology and Intel Virtualizaton Technology with dual network ports and PCIe v2.1 (5.0GT/s) system interface.

Max TDP
Thermal Design Power (TDP) represents the near maximum power a product can draw for a thermally significant period while running commercially available software. For thermal solution requirements please consult the Datasheet, volume 1 (where available).

Intel® Data Direct I/O Technology
Intel® Data Direct I/O Technology is a platform technology that improves I/O data processing efficiency for data delivery and data consumption from I/O devices. With Intel DDIO, Intel® Server Adapters and controllers talk directly to the processor cache without a detour via system memory, reducing latency, increasing system I/O bandwidth, and reducing power consumption.

Virtual Machine Device Queues (VMDq)
Virtual Machine Device Queues (VMDq) is a technology designed to offload some of the switching done in the VMM (Virtual Machine Monitor) to networking hardware specifically designed for this function. VMDq drastically reduces overhead associated with I/O switching in the VMM which greatly improves throughput and overall system performance.

PCI-SIG* SR-IOV Capable
Single-Root I/O Virtualization (SR-IOV) involves natively (directly) sharing a single I/O resource between multiple virtual machines. SR-IOV provides a mechanism by which a Single Root Function (for example a single Ethernet Port) can appear to be multiple separate physical devices.
