Microsoft Azure StorSimple: Primary Volumes now called Tiered Volumes
Published date: August 26, 2015
The StorSimple Primary Volume type is renamed Tiered Volume. The StorSimple device continues to support two volume types: TieredVolume (formerly Primary) and ArchivalVolume. Both of these volume types tier data to the cloud and can have a local presence on the device. Choose Archival Volume if you are working with less frequently accessed archival data. For all other use cases, select Tiered Volume.
