Datacenter-Scale Network Research on FPGAs
The authors describe an FPGA-based datacenter network simulator to allow researchers to rapidly experiment with O(10, 000) node datacenter network architectures. They configure the FPGA hardware to implement abstract models of key datacenter building blocks including servers and all levels of switches. They discuss design and implementation issues of their FPGA models and show that it is practical to prototype and scale the testbed with a few low-cost FPGA boards. Massive Warehouse-Scale Computers (WSCs) are the foundation of widely used Internet services; e.g., search, social networking, email, video sharing, and online shopping.
