PFA：预测性故障分析 (PFA: Predictive Failure Analysis)

PFA is an abbreviation of Predictive Failure Analysis. It is a technique of a mechanism of the computer that is used to predict impending failures of software or hardware components and taking charge by allowing a mechanism to evade or prevent failure cases. It was from the beginning that used a proprietary IBM technology for monitoring impending failure of future of hard disc drives.

PFA是Predictive Failure Analysis的缩写 。 它是计算机机制的一种技术，用于预测软件或硬件组件的即将发生的故障并通过允许某种机制逃避或防止出现故障的情况来负责。 从一开始就使用IBM专有技术来监视硬盘驱动器未来即将发生的故障。

历史 (History)

In 1992, the term PFA and its technology are launched by IBM.

在1992年，术语PFA及其技术由IBM提出 。

This technology is dependent on calculating and estimating various key frameworks of the drive units. The drive firmware compares the calculated and estimated frameworks in opposition to advance established thresholds and analyses the health status of the drive. If the drive emerges probably to fail shortly, then the notification is sent by the system to the disk controller.

该技术取决于计算和估计驱动单元的各种关键框架。 驱动器固件将计算和估计的框架与预先建立的阈值进行比较，并分析驱动器的运行状况。 如果驱动器可能很快就会出现故障，则系统会将通知发送到磁盘控制器。

PFA的优势 (Advantages of PFA)

The prime disadvantages of the technology comprise,

该技术的主要缺点包括：

1. The binary conclusion: presence or absence of notification was the only standing perceptible to the host.

   二元结论 ：通知的存在或不存在是主持人唯一可知的条件。

2. Operating single direction transmissions: the notification is sent by drive firmware.

   运行单向传输 ：通知由驱动器固件发送。

To structure the Self-Monitoring, Analysis, and Reporting Technology (SMART), the technology combined with IntelliSafe. Nevertheless, from a 1940 U.S. military technique, the fundamental proposition regulating PFA was obtained, called “Failure Modes and Effect Analysis (FMEA). It’s a proceeding that is chiefly aimed at examining failures that may happen in the considered possibilities in the following points,

为了构建自我监视，分析和报告技术(SMART)，该技术与IntelliSafe相结合。 然而，从1940年的美国军事技术中，获得了对PFA进行调节的基本命题，称为“失效模式和影响分析(FMEA)”。 此程序主要旨在在以下几点中检查所考虑的可能性中可能发生的故障，

• In the blueprint of a product, the feasible defects

  在产品的蓝图中，可行的缺陷

• Imperfections of a facility provided; or

  所提供设施的不完善之处； 要么

• Defects in the procedure of production

  生产过程中的缺陷

Ahead of the end-user, the focus of the analysis is to predict all the possible elements that would cause to function or activate the approach of failure of the product. Like this, zero shortcomings or highest productivity can be achieved. The concept is to consider the approach of the design or procedure as something that is defective and for that reason bound to fail in one way or another.

在最终用户之前，分析的重点是预测可能导致功能或激活产品故障方法的所有可能因素。 这样，可以实现零缺点或最高生产率。 概念是将设计或过程的方法视为有缺陷的，因此由于某种原因必然会失败。

In terms of keeping from happening or reduce in extent the consequences of probable shortcomings or disasters, the operation has been proven functional and effectual because the alleviating actions that were prepared technically or the fail-safe mechanisms that were installed had considerably enhanced.

在避免发生或减少可能的缺点或灾难的后果方面，该操作已被证明是有效且有效的，因为从技术上准备的缓解措施或已安装的故障安全机制已得到大大增强。

Predictive failure analysis is accurately opposite of the predictive analysis method, for the reason that PFA examines the consequences by proceeding towards the issue with a contrary point of view. Where the unconcerned elements are bound to happen, the risk prevention plans of action policies are put in at the phases, instead of formulating or designing plans from the extremity of post-happening.

预测性故障分析与预测性分析方法完全相反，原因是PFA会从相反的角度着手解决问题，从而检查后果。 在必然发生无关紧要的因素的地方，将采取行动政策的风险预防计划，而不是从发生后的极端时期制定或设计计划。
