Many applications have data encryption requirements on data at rest. Data at Rest Encryption (D@RE) can be used as an encryption solution for VDI without requiring VM changes. This ability also avoids potential performance impact to 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.
