Server requirements for distributed PostgreSQL

PostgreSQL is an open source object-relational database system added to Power Operation to store waveform and alarm analytics information (e.g. probable cause, etc.).

PostgreSQL components can be either:

• Installed on the same machine as the Power Operation Server. (This is the default behavior.)
• Installed in a distributed architecture either on Windows OS or Linux OS.

CPU, RAM, and disk requirements

If installing PostgreSQL on a separate machine from the Power Operation Server, you will need the following for a distributed PostgreSQL environment:

• Disk storage: Minimum 80 GB free disk space
• CPU: Single core with minimum 2GHZ
• RAM: 4 GB

NOTE: The product team has validated the distributed Linux architecture with RHEL 8 - Red Hat Enterprise Linux 8. If you are considering other Linux variants, we recommend to refer to PostreSQL's supported Linux versions.
