Analysis Services includes the following filestore properties. These are all advanced properties that you should not change, except under the guidance of [!INCLUDEmsCoName] support.
::: moniker range="asallproducts-allversions || power-bi-premium-current"
Note
MaxOfflineDatasetSizeGB is the only OLAP property that exclusively applies to Power BI.

::: moniker range="asallproducts-allversions || power-bi-premium-current"
Applies to Power BI only. Maximum size of the offline dataset in memory. This is the compressed size on disk. The default value is 0, which is the highest limit defined by SKU. The allowable range is between 0 and the capacity size limit.

Does not apply to Power BI. A Boolean property that indicates whether database files and cached files are accessed in random file access mode. This property is off by default. By default, the server does not set the random file access flag when opening partition data files for read access.
On high-end systems, particularly those with large memory resources and multiple NUMA nodes, it can be advantageous to use random file access. In random access mode, Windows bypasses page-mapping operations that read data from disk into the system file cache, thereby lowering contention on the cache.
You will need to run comparison tests to determine whether query performance is improved as the result of changing this property. For best practices on running comparison tests, including clearing the cache and avoiding common mistakes, see the SQL Server 2008 R2 Analysis Services Operations Guide. For additional information on the tradeoffs of using this property, see https://support.microsoft.com/kb/2549369.
To view or modify this property in SQL Server Management Studio, enable the advanced properties list in the server properties page. You can also change the property in the msmdsrv.ini file. Restarting the server is recommended after setting this property; otherwise files that are already open will continue to be accessed in the previous mode.
