failover

listen to the pronunciation of failover
Englisch - Türkisch
(Bilgisayar) Bir bilgisar ağında ağdaki akışta bir sorun olduğunda akış yükünü kaldıracak sistem yeterliliği
Englisch - Englisch
A means for ensuring high availability of some critical resource (such as a computer system), involving a parallel, backup system which is kept running at all times so that, upon detected failure of the primary system, processing can be automatically shifted over to the backup
An automatic switch to a secondary system on failure of the primary system

The system experienced numerous failovers during the hurricane.

(Bilgisayar) Failover is the capability to switch over automatically to a redundant or standby computer server, system, or network upon the failure or abnormal termination of the previously active server, system, or network. Failover happens without human intervention and generally without warning, unlike switchover
(Teknoloji) (Technology) Capability to automatically switch to a redundant backup system if the primary system fails, esp. to provide very reliable service on a computer system or network
(Internet Directory Administrator's Guide; search in this book) [definition #2] (Net8 Administrator's Guide; search in this book)
A fault tolerance capability used in clustered servers With failover, if one server in the cluster fails, one or more remaining servers in the cluster will absorb the work of the failed server
Network Registrar feature (as described in RFC 2131) that provides for multiple, redundant DHCP servers, whereby one server can take over in case of a failure DHCP clients can continue to keep and renew their leases without needing to know or care which server is responding to their requests
In a server cluster, the means of providing high availability Upon failure, either of a resource in a group or of the node where the group is online, the cluster takes the group offline on that node, and then brings it online on another node See also node; resource
ensuring high availability
For a Microsoft cluster configuration, the process that occurs when one resource, for example a server, fails and operations are automatically taken over by another resource in the cluster
{i} redundancy within a computer network in order to ensure network availability after the failure of a particular piece of hardware (Computers)
a mode of operation for failure tolerant systems in which a component has failed and its function has been assumed by a redundant component

A transfer of the responsibility to provide an ASE service A failover occurs when a hardware or software failure causes a service to restart on a viable member system
The transfer of operation from a failed component (e g , controller, disk drive) to a similar, redundant component to ensure uninterrupted data flow and operability
Seamless transfer of message traffic to a lower priority circuit on the occasion of the failure of a higher priority circuit
If a network is equipped with redundant resources, such as mirrored servers or tandem load balancers, the secondary device can assume the duties of the primary should the primary fail This can be done manually or automatically depending on the setup
When one individual computer fails, another automatically takes over its request load The transition is invisible to the user
A means for ensuring high availability of some critical resource (such as a computer system), involving a redundant, backup system which is kept running at all times so that, upon detected failure of the primary system, processing can be automatically shifted over to the backup
The process of allocating a resource group to another node according to a failover policy A failover may be triggered by the failure of a resource, a change in the node membership (such as when a node fails or starts), or a manual request by the administrator
A transfer of the responsibility to provide services A failover occurs when a hardware or software failure causes a service to restart on another member system

A fault-tolerant clustering architecture in which two servers share a common set of fault-tolerant fixed disk drives In the event of failure of one of the servers, the other transparently assumes all server processing operations See clustering and fault tolerance
A function to substitute a failed system component for a redundant component In Multi Path Driver, if the current path fails, I/O is rerouted through a redundant path so that the system can continue production operations See also 'Multi Path Driver'
- In the event of a component failure, its function is automatically assumed by a redundant component
