Described are aggregation devices and methods for interconnecting server nodes. The aggregation device can include an input region, an output region, and a memory switch. The input region includes a plurality of input ports. The memory switch has a shared through silicon via (TSV) memory coupled to the input ports for temporarily storing data received at the input ports from a plurality of source devices. The output region includes a plurality of output ports coupled to the TSV memory. The output ports provide the data to a plurality of destination devices. A memory allocation system coordinates a transfer of the data from the source devices to the TSV memory. The output ports receive and process the data from the TSV memory independently of a communication from the input ports.
