Ethernet Network Adapter Intel E810-XXVDA4
iWARP (RDMA over Ethernet) provides converged, low-latency fabric services for data centers by enabling Remote Direct Memory Access. Key components that reduce latency include kernel bypass, direct data placement, and transport acceleration. Intel® Data Direct I/O (DDIO) Technology improves I/O data processing efficiency by allowing server adapters and controllers to access the processor cache directly, reducing latency, increasing I/O bandwidth, and lowering power consumption. The adapter supports PCI-SIG SR-IOV for native sharing of a single I/O resource among multiple virtual machines, and Flexible Port Partitioning (FPP) uses the SR-IOV standard to divide a physical Ethernet device into multiple virtual devices to provide fair bandwidth allocation. Virtual Machine Device Queues (VMDq) offload switching tasks from the virtual machine monitor to networking hardware, reducing VMM overhead and improving throughput and overall system performance.
iWARP RDMA lowers network latency and enables efficient data placement for high-performance applications. Intel DDIO reduces memory detours by allowing I/O devices to interact with CPU cache directly, improving bandwidth and energy efficiency. SR-IOV and Flexible Port Partitioning provide hardware-level virtualization that ensures multiple virtual machines can share physical network resources with predictable performance. VMDq minimizes VMM switching overhead, increasing throughput and reducing CPU load for virtualized environments.
Enable iWARP/RDMA in supported network adapters and configure the operating system and drivers to use RDMA-capable stacks. Ensure Intel DDIO is supported and enabled on the server platform to benefit from direct cache I/O. Configure SR-IOV in the system BIOS/firmware and in the hypervisor to expose virtual functions to guest VMs. Use Flexible Port Partitioning settings to assign bandwidth shares to virtual functions as needed. Enable VMDq in the adapter firmware and hypervisor to offload VMM switching and improve virtualized I/O performance.
Verify compatibility between server CPU, chipset, adapter firmware, and hypervisor versions before enabling DDIO, SR-IOV, FPP, or VMDq. Test configuration in a controlled environment to validate latency, throughput, and fair bandwidth allocation for your workloads.
