Database

Note

A BFS Database that is 2GB in size can contain information for 20 million managed files.

The Managed File System Database is located under /etc/dm/raima/dmfs.There is a Managed File System Database for each client’s managed file system. The Database contains all the information on each file in the managed file system and stores information used in generating a list of files to migrate.

Prior to selecting a file system for management, you must determined the size of the Managed File System Database.

Use the formula below to determine the size:

Database size = ((Number of Directories x 250)+(Number of Files x 650))

The values for the Number of Directories and Files are estimates of the maximum number of files and directories that will reside on the client’s file system. This estimate assumes a typical directory and file name length of 20 characters or less. If the file name length is longer, add that length to the estimate.

For example, if the typical file name length is 40 the equation would look like the following:

Database size = ((Number of Directories x 290)+(Number of Files x 650))
