PFA:預測性故障分析 (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的縮寫 。 它是計算機機制的一種技術,用于預測軟件或硬件組件的即將發生的故障并通過允許某種機制逃避或防止出現故障的情況來負責。 從一開始就使用IBM專有技術來監視硬盤驅動器未來即將發生的故障。
歷史 (History)
In 1992, the term PFA and its technology are launched by IBM.
在1992年,術語PFA及其技術由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.
該技術取決于計算和估計驅動單元的各種關鍵框架。 驅動器固件將計算和估計的框架與預先建立的閾值進行比較,并分析驅動器的運行狀況。 如果驅動器可能很快就會出現故障,則系統會將通知發送到磁盤控制器。
PFA的優勢 (Advantages of PFA)
The prime disadvantages of the technology comprise,
該技術的主要缺點包括:
The binary conclusion: presence or absence of notification was the only standing perceptible to the host.
二元結論 :通知的存在或不存在是主持人唯一可知的條件。
Operating single direction transmissions: the notification is sent by drive firmware.
運行單向傳輸 :通知由驅動器固件發送。
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,
為了構建自我監視,分析和報告技術(SMART),該技術與IntelliSafe相結合。 然而,從1940年的美國軍事技術中,獲得了對PFA進行調節的基本命題,稱為“失效模式和影響分析(FMEA)”。 此程序主要旨在在以下幾點中檢查所考慮的可能性中可能發生的故障,
In the blueprint of a product, the feasible defects
在產品的藍圖中,可行的缺陷
Imperfections of a facility provided; or
所提供設施的不完善之處; 要么
Defects in the procedure of production
生產過程中的缺陷
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.
在最終用戶之前,分析的重點是預測可能導致功能或激活產品故障方法的所有可能因素。 這樣,可以實現零缺點或最高生產率。 概念是將設計或過程的方法視為有缺陷的,因此由于某種原因必然會失敗。
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.
在避免發生或減少可能的缺點或災難的后果方面,該操作已被證明是有效且有效的,因為從技術上準備的緩解措施或已安裝的故障安全機制已得到大大增強。
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.
預測性故障分析與預測性分析方法完全相反,原因是PFA會從相反的角度著手解決問題,從而檢查后果。 在必然發生無關緊要的因素的地方,將采取行動政策的風險預防計劃,而不是從發生后的極端時期制定或設計計劃。
