Article Summary

The Local Filesystem storage node is the default storage node after installing CTERA Portal.

Note

You cannot use Local Filesystem storage node for storage that exceeds 20TB.

When using a Local Filesystem storage node, data blocks are stored in a specific folder in the primary CTERA Portal server's local file system.

CTERA Portal servers set to secondary mode access the storage node by communicating through the primary CTERA Portal server.

Note

CTERA recommends setting the deduplication block size to 512KB or larger. Set the block size in the Virtual Portal Settings window. Access the Virtual Portal Settings window by selecting Settings in the navigation pane and then selecting Virtual Portal, under SETTINGS in the Control Panel content page. In the Virtual Portal Settings window, set the Average Block Size field, under Default Settings for New Folder Groups. The default block size is 512KB.
