Estimating storage space

When you initially configure a Content Manager OnDemand system, you calculate the total amount of disk, optical, and tape storage required to hold the Content Manager OnDemand database, database log files, and reports. You also need to plan for the temporary space needed by Content Manager OnDemand programs. The amount of storage space that you need on your system is usually a factor of how much data that you plan to store in Content Manager OnDemand, how long you need Content Manager OnDemand to maintain the data, the compression ratio that you can expect to achieve on the report data, and the number of copies of reports that you need the system to maintain. If you plan to index your reports on the Content Manager OnDemand server, then you must allocate temporary space for the data indexing program. Temporary space is also required for the data loading program.

After you determine how much storage space you need, you should organize the physical storage devices for the various components of the system, such as the database, and cache storage. If you plan to maintain data in archive storage, then you also need to prepare storage devices for use by the archive storage manager (VSAM or OAM). Physically separating program directories, the database, cache storage, and temporary work spaces can improve performance.
