Intel Optane DC Persistent Memory devices provide data center-class persistent memory technology, which can significantly increase transaction throughput.

Persistent memory can be configured in one of the following ways for use by applications:

• Block mode

• Device DAX mode

• File system DAX mode

The current status of persistent memory support and File System DAX for ext4 and XFS is as follows:

• Block Mode is fully supported in RHEL 7.3 and later.

• Device DAX is fully supported in RHEL 7.4 and later.

• File System DAX as part of RHEL 7.6 subscriptions is fully supported for production deployments of SQL Server 2017.

• File System DAX for ext4 and XFS is Tech Preview in RHEL 7.3-7.6
  (see RHEL 7.6 Release Notes for more details) and is targeted for full support with additional applications in a future minor release of Red Hat Enterprise Linux 7.
