This is a documentation review of chapters VIII. - XI

Looks good, just a few minor comments:

21.9.4. Deploying JPA Cache Stores in Various Containers
The dependency version should be 8.4.0.Final-redhat-1

Deploy JPA Cache Stores in JBoss EAP 6.4 and later
There shouldn't be references to Beta version: (This is repeated multiple times in the document)
JPA Cache Store is not supported in Apache Karaf in JBoss Data Grid 7.1 Beta.

21.10.2. Enabling the Cassandra Cache Store

The infinispan-cachestore-cassandra-8.4.0.ER6-redhat-1-deployable.jar is included in the jboss-datagrid-${jdg-version}-library/ directory, and may be added to any projects that are using the Cassandra Cache Store.

The version should be:
infinispan-cachestore-cassandra-8.4.0.Final-redhat-1-deployable.jar

21.11.1. Custom Cache Stores
Locate the SingleFileStore source code by navigating through jboss-datagrid-7.1.0-sources/infinispan-8.4.0.ER6-redhat-1-src/core/src/main/java/org/infinispan/persistence/file/SingleFileStore.java .

The version should be:
infinispan-8.4.0.Final-redhat-1-src

There are 5 occurrences of 8.4.0.ER6-redhat-1 version used, they should be replaced with 8.4.0.Final-redhat-1

There are 5 occurrences of server:core:8.3, they should be replaced with server:core:8.4 (so that the code snippets can be used)

25.6.1. JBoss Operations Network Plugin Metrics
A space between a word and full stop.
For details about each of these endpoints, see the Getting Started Guide .

25.6.4. Create a New Cache Using JBoss Operations Network
There seems to be missing some substitution in the “Creating a new cache in Remote Client-Server mode” steps:
There are steps like:

From the JBoss Operations Network console, click . (Click on what)
Below the server name, click and then .

25.7.3.2. Manually Adding JBoss Data Grid Instances in Library Mode
Multiple references to JDK 5, I suppose it should be JDK 8.
