针对高速光纤数据存储过程中出现的Aurora协议断链和丢数问题,本文在以Kintex-7 FPGA为控制核心的存储系统上对Aurora协议进行优化。通过对Aurora链路连接状态标志位进行实时监测,增加链路断链重连和重传机制,实现了链路断链情况下的再恢复和重传。多次测试证明,优化后的系统可实现高速率、高可靠性的光纤数据存储,该优化设计对于提高Aurora链路可靠性和恢复断链方面具有一定的参考价值。
Abstract
Aiming at the problem of Aurora protocol disconnection and data loss in the process of high-speed optical fiber data storage,this article optimizes the Aurora protocol on a storage system with Kintex-7 FPGA as the control core.Through real-time monitoring of the Aurora link connection status flag bit,the link disconnection reconnection and retransmission mechanism is added to realize the recovery and retransmission in the case of link disconnection.Many tests have proved that the optimized system can realize high-speed and high-reliability optical fiber data storage.The optimized design has a good reference value for improving Aurora link reliability and broken link recovery.
