The HP 4X DDR IB Switch Module for HP BladeSystem c-Class is a double wide switch module for the c-Class enclosure. It is based on the Mellanox 24-port InfiniScale III 4X DDR InfiniBand switch chip. The HP 4X DDR IB Switch Module for HP BladeSystem c-Class provides 24 InfiniBand 4X DDR ports with 20 Gbps port-to-port connectivity. The ports are arranged as 16 downlinks to connect up to 16 blade servers in the enclosure, and 8 uplinks to connect to the external InfiniBand switches to build an InfiniBand fabric. All links conform to InfiniBand Trade Association (IBTA) specifications. A subnet manager is required to manage and control an InfiniBand fabric. The subnet manager can be provided by either on a rack-mount InfiniBand switch with an embedded fabric manager (also known as internally managed switch) or a host-based subnet manager software on a server.
