The ThinkSystem Marvell QL41232 10/25GbE SFP28 Ethernet Adapters are based on eighth-generation technology from Marvell and feature Universal Remote Direct Memory Access (RDMA) to offer concurrent support for RoCE, RoCE v2, and iWARP. The adapters are available in PCIe and OCP form factors. They are suitable for existing 10Gb customers who want to maintain 10Gb network support and want the investment protection of supporting 25GbE network speeds, but don't need FCoE or iSCSI support.Did you know? The QL41262 adapters and QL41232 adapters only differ in that the QL41232 adapters do not support the CNA functions, FCoE and iSCSI. All Ethernet functionality remains the same across the two adapter families. The adapter supports FastLinQ SmartAN auto-negotiation for simplified connectivity with switches without user intervention. SmartAN automates the connection and control of 10Gb and 25Gb connections based on the capabilities of the cables and switches used. This technology ensures that the connection is made with the highest possible speed with highest possible reliability.
