  2. Single point of failure - Wikipedia

    en.wikipedia.org/wiki/Single_point_of_failure

    Systems can be made robust by adding redundancy in all potential SPOFs. Redundancy can be achieved at various levels. 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 ]

  3. Fault tolerance - Wikipedia

    en.wikipedia.org/wiki/Fault_tolerance

    This is known as N-model redundancy, where faults cause automatic fail-safes and a warning to the operator, and it is still the most common form of level one fault-tolerant design in use today. Voting was another initial method, as discussed above, with multiple redundant backups operating constantly and checking each other's results.

  4. Network topology - Wikipedia

    en.wikipedia.org/wiki/Network_topology

    A fully connected network, complete topology, or full mesh topology is a network topology in which there is a direct link between all pairs of nodes. In a fully connected network with n nodes, there are () direct links. Networks designed with this topology are usually very expensive to set up, but provide a high degree of reliability due to the ...

  5. Mesh networking - Wikipedia

    en.wikipedia.org/wiki/Mesh_networking

    This in turn contributes to fault-tolerance and reduced maintenance costs. [1] Mesh topology may be contrasted with conventional star/tree local network topologies in which the bridges/switches are directly linked to only a small subset of other bridges/switches, and the links between these infrastructure neighbours are hierarchical. While star ...

  6. Redundancy (engineering) - Wikipedia

    en.wikipedia.org/wiki/Redundancy_(engineering)

    Geographic redundancy is used by Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, Netflix, Dropbox, Salesforce, LinkedIn, PayPal, Twitter, Facebook, Apple iCloud, Cisco Meraki, and many others to provide geographic redundancy, high availability, fault tolerance and to ensure availability and reliability for their cloud ...

  7. Standard RAID levels - Wikipedia

    en.wikipedia.org/wiki/Standard_RAID_levels

    Diagram of a RAID 0 setup. RAID 0 (also known as a stripe set or striped volume) splits ("stripes") data evenly across two or more disks, without parity information, redundancy, or fault tolerance. Since RAID 0 provides no fault tolerance or redundancy, the failure of one drive will cause the entire array to fail, due to data being striped ...

  8. Reliability block diagram - Wikipedia

    en.wikipedia.org/wiki/Reliability_block_diagram

    A reliability block diagram. An RBD is drawn as a series of blocks connected in parallel or series configuration. Parallel blocks indicate redundant subsystems or components that contribute to a lower failure rate. Each block represents a component of the system with a failure rate. RBDs will indicate the type of redundancy in the parallel path ...

  9. Spanning Tree Protocol - Wikipedia

    en.wikipedia.org/wiki/Spanning_Tree_Protocol

    The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails.
