LENOVO, INC. 7XC7A05523 Intel XXV710-DA2 - Network adapter - PCIe 3.0 x8 low profile - 25 Gigabit SFP28 x 2 - for ThinkAgile VX Certified Node 7Y94, 7Z12; ThinkAgile VX3320 Appliance; VX7820 Appliance

Mobile and cloud application acceleration. Intels Data Plan Development Kit (DPDK) delivers an open driver where users can fine-tune small packet performance. Virtualization performance. With Intel Virtualization Technology (VT), the X710 family of adapters delivers outstanding I/O performance in virtualized server environments. These adapters reduce I/O bottlenecks by providing intelligent offloads for networking traffic per virtual machine (VM), which enables near-line rate speeds for small packets and supports almost an unlimited amount of isolated traffic flows so that you can scale your cloud environment. VXLAN/NVGRE hardware offloads. These stateless offloads preserve application performance for overlay networks. With these offloads, it is possible to distribute network traffic across CPU cores. At the same time, X710 offloads LSO, GSO, and checksum from the host software, which reduces CPU overhead. Next-generation VMDq. The X710 adapters support up to 256 VMDq VMs and offer enhanced Quality of Service (QoS) feature by providing weighted round-robin servicing for the Tx data. The adapters offload the data-sorting functionality from the hypervisor to the network silicon, which improves data throughput and CPU usage. Low latency. Intel Ethernet Flow Director delivers hardware-based application steering and Intel Data Direct I/O makes the processor cache the primary destination and source of I/O data rather than main memory. Combined, latency is reduced and Intel reports a three-fold improvement in RPS.
