受台风影响,近期,河南遭受极端暴雨天气,千年罕见,此次暴雨导致河南多地损失惨重。对于服务器而言,机房的日常运维是非常重要的,那么在遭遇如此汛情之时,数据中心应当如何应对呢?
首先是数据中心建设,不管是国内服务器还是国外服务器,在对于数据中心的选址时除考虑经济环境、政策环境、交通便利、配套设施等因素外,地理条件同样要认真考量,尽量选择地势较高、排水良好的位置,这样降水量大时可减少积水。
此外,从台风山竹到此次汛情,自然灾害在数据中心故障原因中占据相当的比例,影响力也远超一般故障。因此,数据中心应针对自然灾害,建立完善的应急预案,定时检查应急物资,组织演练,有备无患。
那么数据中心在预防汛情的日常运维中要怎么做呢?日常运维要对数据中心及周边的防水工程、排水设施、应急物资、漏水警报等做检查,具体为:
1)日常巡检应检查建筑屋面、夹层、墙体、门窗等是否有明显可见的破损和开裂,重点检查接缝拼接区域,定期清除雨水箅子上的杂物,保证排水管道畅通;
2)日常巡检应检查制冷水系统管道、空调间、冷凝水管、消防管道、应急消防水箱、地下泵房、排水管道等水源区域,及时清理排水沟杂物;
3)定期检查应急储备物资是否充足,包括设备备件、防水塑料布、沙袋、水桶、排水泵、软管、毛巾、雨具等;
4)检查漏水警报的可靠性,重要区域保持定期测试漏水绳的响应时间和准确度;
5)在空调直接放置在设施间的区域,应对水管压力表、阀门等易损点,安装透明隔水板或防水护套,避免密封不严导致水直接喷溅到关键设备上;
6)有条件的“中心”可在风险较高的电池间加装电池架顶部的防水托盘,以避免水渍渗漏到电池上,引起短路。
