I/O Expansion Modules InfiniBand* (SDR) Module (AXXIBIOMOD)
4. InfiniBand* (SDR) Module (AXXIBIOMOD)
The 4X SDR InfiniBand* I/O module is based on the Mellanox InfiniHost* MT25204 device with
the integrated Physical Layer SerDes. This card has a single 4X InfiniBand* copper port for
connecting InfiniBand* traffic at up to 10Gbps. This section provides a high-level description of
the implementation of this I/O module. This module is expected to end-of-life with the
S5000PAL/S5400SF server boards, not available for extended life support
