Emergency preparedness and response plan 1) emergency response (1) If a major accident occurs, the project should set up emergency response teams, chaired by the project manager, head of production and safety coordinators, professional foreman for the crew, primarily responsible for the orderly rescue when an emergency occurs or processing, outsourcing, team manager and support staff, assisting the Deputy Project Manager for related auxiliary work. (2) after the accident, the project manager is responsible for field commander, advance the establishment of emergency response team personnel, accountability, seriously injured officers sent out rescue, have procedures to deal with accidents, incidents, maximum reduction in casualties and property loss. (3) If an accident occurs, press Division in advance for emergency personnel cleared, concentrate manpower and material and financial resources to rescue the injured, decrease of the maximum loss. (4) after the accident processing work (5) identified the cause of the accident and the person responsible. (6) the written report to the supervisor in writing, including the time and place of the accident, injury (death) person's name, sex, age, trades, injuries, injuries. (7) the development of effective preventive measures to prevent such accidents from happening again. (8) education of all personnel of the organization. (9) informed criticism of those responsible. (10) all personnel read out the results, and responsible disposal. (11) maintenance of emergency supplies, maintenance and testing ① strengthening the day-to-day management of the various fire fighting equipment fire-fighting equipment, authorities should be staffed, equipped with fire extinguishers. Fire hydrants identified person responsible for regularly inspecting, testing, at any time in good condition. ② Guard monthly check-fire extinguishers and fire-fighting equipment. ③ once every quarter, inspections and tests of a fire hydrant in good condition. 2), plans to develop (1) casualties occurred in construction, such as accidents or accidents of the direct economic
1. Thin Provisioning(自动精简配置)技术
工作原理:
在创建“瘦”卷时,预分配一个虚拟的逻辑卷容量大小,而只是在
实际写入数据时才分配物理空间给这个卷。这样我们可以轻易的创建出总逻辑容
量超出物理磁盘空间的多个“精简卷”,而无须为将来可能达到的数据量提前“买
单”。在应用产生的数据确实需要增加驱动器时,我们也可以灵活地在线调整卷
的大小。
可能带来的问题:
当每个卷已使用的容量总和超过阵列的物理容量时,将无法再写入
数据,并导致应用出错。于是设置空间预警的功能就相当重要,比如在物理空间
占用达到 85%时向管理员发出通知。删除文件空间释放的问题,参考《自动精简
配置存储方案选型分析》与《专家博客:自动精简配置的利与弊》。

自动精简配置是一项利用虚拟化方法减少物理存储部署的技术,可
最大限度提升存储空间利用率。存储系统逐年扩展。为确保存储容量足够使用,
用户往往会部署多于实际需求的物理存储空间——“安全起见”。但在实际使用
过程中,部署容量通常未受到充分利用。行业研究组织发现在某些项目中,实际
使用容量仅占部署容量的 20%—30%。因此,“自动精简配置”技术应运而生,
旨在实现更高的存储容量利用率,并带来更大的投资回报。
使用自动精简配置,所有的用户容量都以虚拟存储的形式分配,而实际的物理磁
盘空间将根据实际使用情况进行分配。所有物理磁盘被视为一个磁盘池进行管理,
按照写入虚拟卷的数据量完成分配。如此一来,未使用的物理磁盘容量显著降低,
进而实现更高效的存储作业。另外,需要添加额外物理磁盘时,预定义阈值将发
出警告,以避免容量短缺。
例如,某位用户向服务器管理员请求分配 10TB 的资源。虽然可能
确实需要 10TB 的物理存储容量,但根据当前使用情况,分配 2TB 就已足够。因
此,系统管理员准备 2TB 的物理存储,并给服务器分配 10TB 的虚拟卷。服务器
即可基于仅占虚拟卷容量 1/5 的现有物理磁盘池开始运行。这样的“始于小”方
案能够实现更高效地利用存储容量。
当虚拟卷需要更多的物理容量时(如下图所示),会占用现有的物
理卷容量。为避免出现容量短缺,可使用预定义的使用阈值来监控物理磁盘池。
例如,将阈值定义为整个磁盘池容量的 80%,则在达到阈值时,系统管理员就会
收到扩展物理磁盘数量的警报。因而,您无需停止系统,即可添加新的驱动器,
同时确保系统运行的连续性。
