Vertica Analytics Platform Version 10.0.x Documentation

Using Eon Mode

You can operate your Vertica database in Eon Mode instead of in Enterprise Mode. The two modes differ primarily in how they store data: 

  • Eon Mode databases use communal storage for their data.
  • Enterprise Mode databases store data locally in the file system of nodes that make up the database.

These different storage methods lead to a number of important differences between the two modes. In Enterprise Mode, each database node stores a portion of the data and performs a portion of the computation. In Eon Mode, computational processes are separated from a communal (shared) storage layer, which enables rapid scaling of computational resources as demand changes.

For more on how these two modes compare, see Vertica Architecture: Eon Versus Enterprise Mode.
