===== Setup System Server Type Configuration =====

There are 2 options when configuring the System Server Type: single and multi

  'single'  - Single-Server install is used when there will only be 1 server configured

              on the system. It can also be used for production systems, if the plan is

              to stay single-server.

  'multi'   - Multi-Server install is used when you want to configure multiple servers now or

              in the future. With Multi-Server install, you can still configure just 1 server

              now and add on addition servers/modules in the future.

Select the type of System Server install [1=single, 2=multi] (2) > 1

===== Setup Storage Configuration =====

----- Setup Performance Module DBRoot Data Storage Mount Configuration -----

Columnstore supports the following storage options...

  1 - internal.  This uses the linux VFS to access files and does

      not manage the filesystem.

  2 - external *.  If you have other mountable filesystems you would

      like ColumnStore to use & manage, select this option.

  3 - GlusterFS *  Note: glusterd service must be running and enabled on

      all PMs.

  4 - S3-compatible cloud storage *.  Note: that should be configured

      before running postConfigure (see storagemanager.cnf)

  * - This option enables data replication and server failover in a

      multi-node configuration.

These options are available on this system: [1, 2, 4]
