The image shows four boxes that each represent a JVM in a Coherence cluster. Each JVM contains an application box and a near cache box. The near cache box for JVM one and two each contain: a logical cache box, a local cache box, and a partitioned cache box that contains a logical cache box. The near cache box for JVM three and four each contain: a logical cache box, a local cache box, and a partitioned cache box that contains a logical cache box together with a primary storage box and a backup box. Data is labeled A through D and is located in all the logical caches of each JVM. The application in JVM one is performing a single put operations for data that is labeled D. 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 D is being stored to the primary storage on JVM four and is also shown on JVM three backup storage, but it is being invalidated (symbolized with and X) from the local cache of JVM three and JVM four; data C is being stored to primary storage on JVM three and is also shown on JVM four backup storage, but it is being invalidated (symbolized with an X) from the local cache of JVM one and JVM three.
