In
the computer the fault tolerant system means a system that is designed
according to the fault tolerance. In the presence of errors and breakdown this
must give the level of satisfaction related to work. In this mechanism the
complete system must be integrated according to some rules and regulations
according to different system that are used in the major companies. In other
words, the form of full hardware redundancy is included in the fault tolerance
computing. In lock system two systems are operated with one another in tandem,
mirroring identical applications and executing instructions. This all going to
happen in that way that if the primary system has to face hardware failure , an
identical application is going to run in the secondary system that show no loss
of service and zero downtime in the system. Specialized hardware must be
required for the fault tolerant computing that detects the fault in the
components immediately and in perfect tandem, the mirrored system keeps
running. It also eliminate the downtime of server , so all the data lost can be
saved and maintain the huge amount of data in proper manner.
Comparison with high availability and
The Fault tolerance system and its function
Fault
tolerance system is the system that provides a great protection from system
failure but issue with this system is that it requires high cost for
implementation in the system. A fully redundant set of hardware are going to
used in this system that are connected with the primary system of the major
system. But if we talk about the high availability architecture, this system is
very cost effective but on other hand brings downtime which is costly for the
system. In industries or network the faulty tolerance system used where the
downtime of the server not acceptable and much loss have to be bear in that
case. Many manufacturing equipments and devices sue the faulty tolerance system
in their network. And complicated infrastructure must be required the faulty
tolerance system to get complete knowledge about hardware and system and data.
High availability architecture provides high software protection whereas the
fault tolerance system provides little protection against software failure. For
replicated or integrated the highly availability architecture didn’t require
any piece of IT infrastructure. Many organizations prefer to use the fault
tolerance system because they can comprise on software application but the
hardware replicated cause many problems in the overall system. (Marashi)
Ways of supporting the systems and
The Fault tolerance system and its function
Fault
tolerance system ensures that the system request can be executed without any
hurdle in more complex system and networks. But it also takes mush time for
reroute requests and system adapts through its redundancies. Any software
problem that cause some failure may spill over in the mirrored system that help
in making and running the system in smooth manner and also provide many
facilities to save from downtime. The main reason behind creating the fault
tolerance system is to avoid the point of disruption that provide better
ensurance for business continuity and high availability for critical system or
application related to any mission. With ensuring no loss, backup components
are automatically take place of failed components in the fault tolerance
system. it provide many benefits like power source that use alternate resources
by making fault tolerance like power generator usage that help in electrical
failure and avoid disturbance in the smooth working. System software includes
keeping a backup of the software that instantly used in case of failure. The
customer information from data base easily copied in another system or machine.
Operation cam automatically redirected to second data base of the primary data
base goes down. Hardware system means that equivalent or identical system can
be prepared as backup to avoid system failure. And the all system can be run on
mirrored system as backup server in parallel ways. (future-processing.pl)
Maintain integrity and The Fault
tolerance system and its function
The
fault tolerance system help in maintaining the integrity of the complete system
r network at the large scale. It means that the huge amount of data in the
large organizations or network never lost due to physical issues and complete
protection must be provided to the for maintaining the integrity of the system
. Because if the security of the system is not strong and also not avoiding the
lost of downtime then the overall performance of the system going down and it
will not produce the required result on time. Further issue is that the
handling of data at large scale is not an easy task and if any data going to
lost due to system failure and behind this the reasons appear for physical
component than the overall impression is going very poor and the performance of
the company going down. So the fault tolerance system is very helpful in
maintaining the integrity of the data and also for the system. (imperva.com)
Five 9 uptime Requirements and The
Fault tolerance system and its function
There
are normally two type of behavior that are used in the fault tolerance system
for the better results and also cause problems in the production system. At
application level the working of fault tolerance system is good but when it
moves to manufacturing then the fault tolerance system help in handles the
byzantine behavior and fail stop behavior in the system. Byzantine behavior
means that the system never produces required data or behavior and this failure
happen due to corrupted data or information in the operating system. Fail stop
behavior occur when the suddenly halts or few parts going to fail while running
the system. Data base inaccessibility and server downtime come in this
category.
There
are different tools used in the systems to build the fault tolerant system like
circuit breaker pattern, load balancing, actor model, non blocking I/O using
messaging queue and other options. These tools are helping to produce or
develop the fault tolerance system in the major system according to demand and
requirement of the system and give the results and also response according to
requirement of the system because in different systems different reasons happen
for the failure and the fault tolerance system help in sort out such type of
problems of the hardware and also software. (()
Conclusion on The Fault tolerance
system and its function
At
the end, it can say that the fault tolerance system is very helping tool for
the system and provide better protection for all the systems and its data and
also handle huge amount of data in effective manner. There is lot of issue of
hardware, soft ware and power appear in the major systems or network and this
system provide a support to all the systems form data failure and system
downtime. Because such downtime may cause many data lost and the information of
the company may also going to be damage or its customer information also going
to be lost due to downtime of system. It also affects the performance of the
network or system. so such helping tools provide better safety and protection
against data lost and in both software and hardware direction. It’s no doubt
costly for the major systems but due to its effective usage and better
protection of data, major organizations must adopt this system and use this
helping tool in their daily routine due to avoid any data lost and problem.
