The behavior of the storage engine once VertiPaq Nonpaged Memory reaches the VertiPaq Memory Limit depends on the VertiPaq paging policy that is configured in the instance's SSAS properties. The default paging policy of 1, will allow paging to the Windows page file. This means that if the required memory to store what is needed in the VertiPaq engine exceeds the configured limit, paging will occur to the Windows page file. However, if the paging policy is changed to 0, this disables paging. If the required memory exceeds the limit with this configuration, queries to the instance may fail and out-of-memory errors will be experienced. Note this conditions is only valid for SSAS 2014. Other conditions are available to support other versions of SSAS.
