M4121-SFP28-M2 (Z) is a PCIe v3.0 x4 developed based on the Mellanox ConnectX-4 main control solution M. 2-to-1 single port fiber 25G Ethernet network adapter, equipped with SRIOV technology, provides dedicated adaptation for virtual machines in servers Equipping resources to meet the functions of network isolation and protection, in addition to I/O virtualization technology providing higher servers for data centers Utilization rate, while meeting customer requirements for reducing operating costs and on-site wiring complexity, supporting 1/10/25G three speed connections to achieve full capacity Adequate virtualization applications for current network infrastructure. Unique functional design 1. This network adapter unloads protocol processing and data movement overhead (such as RDMA and send/receive semantics) from the CPU Realize efficient computing to provide more processor power for applications. 2. This network adapter supports SRIOV technology, which divides the PF into multiple VFs for use by upper layer virtual machines, equivalent to virtual machines Bypass VI and directly use PCIe devices to process I/O and transmit data.
