AI Technical Summary
Technical Problem
Existing RDMA transfer systems face increased processing load due to frequent communication between RNICs and multiple processor boxes, which is inefficient and burdensome.
Method used
A data transfer system with a centralized storage device managing queues for Work Queue Elements (WQE) outside processor boxes, reducing direct RNIC communication and utilizing RNICs for RDMA transfers based on these queues.
Benefits of technology
Reduces RNIC processing load, improves WQE search speed, and enhances throughput and latency by minimizing direct RNIC-processor box communication, while allowing flexible resource management and load balancing.

Abstract
A data transfer system (10) comprises a plurality of processor boxes (20) each comprising processors (21 and 22), a memory (23) that is provided with a first queue (23A or 23C) on which a WQE is loaded by the processors (21 and 22), and a housing (24) that accommodates the processors (21 and 22) and the memory (23). The data transfer system (10) further comprises: a storage device (61) that is provided outside the plurality of processor boxes (20) and that is provided with a second queue (61A or 61C) in which the WQE stored in the first queue of the memory (23) of each of the plurality of processor boxes is stored; and at least one RNIC (40) that performs RDMA transfer on the basis of the WQE stored in the second queue.
