The image shows four boxes that each represent a JVM in a Coherence cluster. Each JVM contains and application box and a DistributedCache Map box. Each DistributedCache Map box contains three boxes: a logical cache box, a primary storage box, and a backup box. The application in JVM one is performing a single put operations for data that is labeled A. The application in JVM two is performing a single put operations for data that is labeled C. The put operations are performed on the logical cache of the respective JVMs. However, the data is being stored in the other JVMs as follows: data A is being stored to the primary storage on JVM one and is also shown on JVM four backup storage; and, data C is being stored to primary storage on JVM three and is also shown on JVM one backup storage.
