Linux OS PlatformVersion
Red Hat Enterprise Linux7.3 or later
CentOS7.3 or later
Oracle Enterprise Linux7.3 or later
Ubuntu LTS16.04 or later

DM can be deployed and run on Intel architecture servers and mainstream virtualization environments.

DM can be deployed and run on a 64-bit generic hardware server platform (Intel x86-64 architecture). For servers used in the development, testing, and production environments, this section illustrates recommended hardware configurations (these do not include the resources used by the operating system).
