 <div class="block">A durable memory configuration for an Apache Ignite node. The durable memory is a manageable off-heap based memory
  architecture that divides all expandable data regions into pages of fixed size
  (see <a href="../../../../org/apache/ignite/configuration/DataStorageConfiguration.html#getPageSize--"><code>getPageSize()</code></a>). An individual page can store one or many cache key-value entries
  that allows reusing the memory in the most efficient way and avoid memory fragmentation issues.
  <p>
  By default, the durable memory allocates a single expandable data region with default settings. All the caches that
  will be configured in an application will be mapped to this data region by default, thus, all the cache data will
  reside in that data region. Parameters of default data region can be changed by setting
  <a href="../../../../org/apache/ignite/configuration/DataStorageConfiguration.html#setDefaultDataRegionConfiguration-org.apache.ignite.configuration.DataRegionConfiguration-"><code>setDefaultDataRegionConfiguration(DataRegionConfiguration)</code></a>.
  Other data regions (except default) can be configured with
  <a href="../../../../org/apache/ignite/configuration/DataStorageConfiguration.html#setDataRegionConfigurations-org.apache.ignite.configuration.DataRegionConfiguration...-"><code>setDataRegionConfigurations(DataRegionConfiguration...)</code></a>.
  <p>
  Data region can be used in memory-only mode, or in persistent mode, when memory is used as a caching layer for disk.
  Persistence for data region can be turned on with <a href="../../../../org/apache/ignite/configuration/DataRegionConfiguration.html#setPersistenceEnabled-boolean-"><code>DataRegionConfiguration.setPersistenceEnabled(boolean)</code></a>
  flag. To learn more about data regions refer to <a href="../../../../org/apache/ignite/configuration/DataRegionConfiguration.html" title="class in org.apache.ignite.configuration"><code>DataRegionConfiguration</code></a> documentation.
  <p>Sample configuration below shows how to make 5 GB data regions the default one for Apache Ignite:</p>
