Data in an Exasol database is stored on data volumes, which are assigned to disks defined as block storage devices on each host. The storage devices (disks) must be prepared before you install Exasol.

This article describes how to ensure that the general requirements for data storage in an Exasol database are met before you continue with the installation.

How to add physical and logical devices on the hosts is not covered in this documentation. To know how to add and mount disks, refer to the documentation for your operating system.
