Many SQL Server applications have data encryption requirements, specifically on data at rest. Data at Rest Encryption (D@RE) can be used as an encryption solution for SQL Server without requiring any database or application changes. This also avoids any potential performance impact to the database server or the applications and has no performance impact on the array.
D@RE is enabled by default on the PowerStore array, so no configuration steps are necessary to protect the drives.
