Lenovo Networking Options for Flex System(2)

The CN4054S 4-port and CN4052S 2-port 10Gb Virtual Fabric Adapters are VFA5.2 adapters that are supported on ThinkSystem and Flex System compute nodes. The CN4052S can be divided into up to eight virtual NIC (vNIC) devices per port (for a total of 16 vNICs) and the CN4054S can be divided in to four vNICs (for a total of 16 vNICs). Each vNIC can have flexible bandwidth allocation. These adapters also feature RDMA over Converged Ethernet (RoCE) capability, and support iSCSI, and FCoE protocols, either as standard or with the addition of a Features on Demand (FoD) license upgrade. The adapters are shown in the following figure. The CN4054S and CN4052S look the same.

The ThinkSystem QLogic QL45214, QL45212 and QL45262 network adapters for Lenovo Flex System are based on eighth-generation Ethernet technology from Cavium and feature Universal Remote Direct Memory Access (RDMA) to offer concurrent support for RoCE, RoCE v2, and iWARP. The adapters are for customers looking for end-to-end 50 Gb and 25 Gb Ethernet speeds in their Flex System environment as well as those who want to maintain their existing 10Gb networking infrastructure while preparing for future upgrades to 25Gb or 50 Gb network speeds.
