Study on the Influence on HDD from Fire Extinguishing System Triggering in Data Center

本文从探索影响数据中心基础设施环境在消防环境下的可靠性因素作为目标,从数据中心常用的气体灭火种类、数据存储磁盘的常见种类和基本构成作为出发点,量化不同种类的气灭储存和喷射压力,并设计机械磁盘在不同模拟噪音环境下运行状态实验,有效说明了气灭系统工作噪音对工作中的磁盘读写可用性的潜在影响。本文最后总结并提出减小气灭触发时对磁盘及数据的损害的建议。

This paper aims to explore the factors affecting the reliability of the data center infrastructure environment from the fire protection aspect,introduced the types of gas fire suppression system commonlyused in data centers,as well the common types and basic composition of data storage disks.In order to quantify different kinds of gas suppression system of its storage and injection pressures,we designed and implemented the operation state experiment of HDD under different simulated noise environments.This paper effectively illustrates the potential impact of the operating noise of the gas extinguishing system on the HDD read/write availability.Finally,this paper summarizes and puts forward some suggestions on how to reduce the damage to disk and data when the gas suppression system is triggered.
