I am purchasing 36-node cluster that will be integrated to already existing system. I am exploring the possibility to use two 24 4X port IB edge switches in core/leaf design that have maximum capability of 960Gb (DDR)/480Gb (SDR). They would be connected to the main Qlogic Silverstorm switch. I would appreciate receiving some info regarding the communication overhead incurred by this setup. I am trying to minimize the cost of IB communication hardware. It looks like buying single 48-port switch is really an expensive option.
