Storage interconnection optical network architecture and communication method based on microring resonator

Abstract

The invention provides a storage interconnection optical network framework based on a micro-ring resonator and a communication method thereof. The network framework comprises a heat dissipation layer, a second light layer, a first light layer, a laser layer and an electric layer, which are up-down successively arranged. Multiple groups of processor cores and Ranks of storage systems are arranged on the electric layer. Multiple groups of optical networks are arranged on the light layers. The electric layer is connected with the optical layers via TSV lines. The communication method comprises steps of distributing emission light waves to each group of the processor cores which will select corresponding communication wave lengths; converting to-be-sent electric signals into optical signals so as to send allow the light waves to carry the to-be-sent information and send the to-be-sent information to a storage system end via the optical networks; demodulating the optical signals into electric signals and transmitting the electric signals into the Ranks of the storage systems; after response signals are returned, coupling corresponding wave lengths and carrying out demodulation; and converting the optical signals into electric signals by the processor core ends and sending the electric signals to the processing cores. According to the invention, network transmission power consumption is reduced and overall average power consumption of memory accessing is reduced.
