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.

Specifications

The QLogic 25 Gb and 50 Gb adapters have the following technical specifications:

Cavium FastLinQ 45000 ASIC

PCIe 3.0 x16 host interface (standard Flex System compute node I/O adapter connection)

Two internal 50GBase-KR SERDES interfaces (each interface is 2 lanes of 25 Gb/s) to the chassis midplane

QL45214: Four 25Gb connections

QL45212 and QL45262: Two 50 Gb connections (each connection is two 25 Gb lanes combined)
