The ArcGIS Enterprise configuration store and associated directories (such as content, cache, and jobs) store dynamic data that grows over time. It is a best practice to place these directories on a dedicated, large partition separate from the operating system and the software installation files. In the given scenario, the /data partition has the most available space (150 GB) and, by convention, is intended for application data. Placing the directories here ensures sufficient space for growth and separates volatile data from static software binaries, which are typically installed in /opt.

A. /home: The /home partition (20 GB) is too small for the potential growth of ArcGIS Enterprise data and is conventionally reserved for user-specific configuration files and personal data.

C. /opt: The /opt partition is the standard location for installing optional, third-party software packages (the ArcGIS Enterprise binaries). Co-locating growing data with static application files is not a recommended practice.

ArcGIS Server System Requirements: "The directories used by ArcGIS Server to store caches and other data can also be large. For example

if you create caches for your services

the disk space required can easily be tens or hundreds of gigabytes... For this reason

it's important that you have a separate disk or partition for the server directories."

About Server Directories: "The server directories store content

configuration

and logging information used by your GIS server... You should ensure that the account that will be used to run ArcGIS Server has write access to the server directories and that there is sufficient disk space to store the directories."

ArcGIS Enterprise 11.2

Portal for ArcGIS System Requirements: "The portal's content directory stores content saved and uploaded by users... The content directory can grow very large depending on the number and size of the files saved by users. It is highly recommended that you place the directory on a separate

highly available disk."
