Determining Disk Space Requirements

Essbase uses disk space for its server software and for each database. Before estimating disk storage requirements for a database, you must know how many dimensions the database includes, the sparsity and density of the dimensions, the number of members in each dimension, and how many of the members are stored members.

  To calculate the disk space required for a database:

  1. Calculate the factors identified in Calculating the Factors to Be Used in Sizing Disk Requirements.

  2. Calculate the disk space required for a single database.

    See Estimating Disk Space Requirements for One Database.

  3. Calculate the total disk space required for Essbase Server.

    See Estimating the Total Essbase Server Disk Space Requirement.

Note:

The database sizing calculations in this chapter assume an ideal scenario with an optimum database design and unlimited disk space. The space required is difficult to determine precisely because most multidimensional applications are sparse.
