Redundant I/O domains [12] or I/O partitions [13] for providing virtual I/O to guest virtual machines. Computer clustering capability with failover capability, for complete redundancy of hardware and software. Dynamic software updating to avoid the need to reboot the system for a kernel software update, for example Ksplice under Linux.
Geographic redundancy corrects the vulnerabilities of redundant devices deployed by geographically separating backup devices. Geographic redundancy reduces the likelihood of events such as power outages, floods, HVAC failures, lightning strikes, tornadoes, building fires, wildfires, and mass shootings disabling most of the system if not the entirety of it.
Frontier Communications Statement Regarding Network Reliability and Redundancy Background: The Federal Communications Commission released a report today that outlines 9-1-1 service interruptions ...
Redundancy (information theory), the number of bits used to transmit a message minus the number of bits of actual information in the message; Redundancy in total quality management, quality which exceeds the required quality level, creating unnecessarily high costs; The same task executed by several different methods in a user interface
Two kinds of redundancy are passive redundancy and active redundancy. Passive redundancy is used to achieve high availability by including enough excess capacity in the design to accommodate a performance decline. The simplest example is a boat with two separate engines driving two separate propellers.
High-availability Seamless Redundancy (HSR) is a network protocol for Ethernet that provides seamless failover against failure of any single network component. PRP and HSR are independent of the application-protocol and can be used by most Industrial Ethernet protocols in the IEC 61784 suite. HSR does not cover the failure of end nodes, but ...
Systems can be made robust by adding redundancy in all potential SPOFs. Redundancy can be achieved at various levels. The assessment of a potential SPOF involves identifying the critical components of a complex system that would provoke a total systems failure in case of malfunction. [2]
