Supermicro SBM-IBS-Q3616 InfiniBand Switch Module

InfiniBand Switch Module
The InfiniBand Switch Modules are switch-based, point-to-point bi-directional serial link systems. They provide high-speed interconnectivity among the blade modules and to external InfiiniBand peripherals and are especially useful in supporting clustered High-Performance-Computing. The SBM-IBS-001 InfiniBand switch supports up to fourteen internal and 10 external 4X DDR connections (20-Gbps). The SBM-IBS-Q3616 InfiniBand Switch Module supports up to 20 internal and up to 16 external 4X QDR connections (40 Gbps). The SBM-IBS-Q3616M InfiniBand Switch Module adds the capability for installation of a BMB-CMM-002 mini-CMM, thus allowing dual/redundant links from each Blade (requires AOM-IBH-QDD) to redundant switches. The SBM-IBS-Q3618 InfiniBand Switch Module supports up to 18 internal and up to 18 external 4X QDR connections (40 Gbps) .

InfiniBand Pass-Through
The SBM-IBD-D14 InfiniBand Pass-Through is a non-configurable pass-through with fourteen internal downlinks to blades and fourteen external 4x DDR (20Gbps) connections using CX-4 cables of up to 3M length.
