Lenovo Flex System CN4052S Network Adapter
The adapters offer CN4052S 10 GbE connections and are cost- and performance-optimized for integrated and converged infrastructures. They offer a "triple play"of converged data, storage, and low latency RDMA networking on a common Ethernet fabric. The adapters provides customers with a flexible storage protocol option for running heterogeneous workloads on their increasingly converged infrastructures. Multiprotocol support for 10 GbE The adapters offer CN4052S 10 GbE connections and are cost- and performance-optimized for integrated and converged infrastructures. They offer a "triple play"of converged data, storage, and low latency RDMA networking on a common Ethernet fabric. The adapters provides customers with a flexible storage protocol option for running
heterogeneous workloads on their increasingly converged infrastructures. Virtual NIC emulation The Emulex VFA5.2 family supports three NIC virtualization modes as standard:Virtual Fabric mode (vNIC1), switch independent mode (vNIC2), and Unified Fabric Port (UFP). With NIC virtualization, each of the physical ports on the adapter can be logically configured to emulate up to four virtual NIC (vNIC) functions with user-definable bandwidth settings. Additionally, each physical port can simultaneously support a storage protocol (FCoE or iSCSI). Full hardware storage offloads These adapters support an optional FCoE hardware offload engine, which is enabled via Lenovo Features on Demand (FoD). The offload engine accelerates storage protocol processing and delivers up to 1.5 million I/O
operations per second (IOPS). This enables the servers processing resources to focus on applications and improves the servers overall performance. Lenovo Features on Demand (FoD) The adapters use FoD software activation technology. FoD enables the adapters to be initially deployed as low-cost Ethernet NICs, and later upgraded in the field to support FCoE or iSCSI hardware offload. Emulex Virtual Network Acceleration (VNeX) technology support Emulex VNeX supports Microsoft network virtualization by using generic routing encapsulation (NVGRE) and VMware-supported virtual extensible LAN (VXLAN). These technologies create more logical LANs for traffic isolation that are needed by cloud architectures. Because these protocols increase the processing burden on the servers processor, the adapters
have an offload engine that is designed specifically for processing these tags. The resulting benefit is that cloud providers can use the benefits of VxLAN/NVGRE with no reduction in the servers performance.
