Maximum Capacity Specifications (Analysis Services)

The following tables specify the maximum sizes and numbers of various objects defined in Analysis Services components under different server deployment modes.

This topic contains the following sections:

Multidimensional and Data Mining (DeploymentMode=0)

SharePoint (DeploymentMode=1)

Multidimensional and Data Mining (DeploymentMode=0)

MOLAP storage mode, which stores both data and metadata, has additional physical limits on file sizes. String store files are a maximum size of 4 GB by default. If you require larger files for string stores, you can specify a different string storage architecture. For more information, see Configure String Storage for Dimensions and Partitions.
