Clone function
Clone is a complete copy of the source volume (real-time cloning, only support for copying within this device), unlike snapshots, which is a 1: 1 copy of the source volume. When the source volume data is corrupted, it can be recovered from the data of the target volume Source volume data.
-
Snapshot function
A snapshot is a snapshot of a given volume at a given time, and when the snapshot is created, the data is not actually copied, and the source volume changes the data to a snapshot resource volume when the source volume changes. Snapshots and source volumes to recover data.
-
Volume copy function
A volume copy is a complete copy of the source volume or a remote copy (a full copy of a moment, a local volume copy, or a remote volume copy across the device). Similar to cloning, source volume data can be recovered from the data of the target volume.
-
Synchronous mirror function
Synchronous mirror is a real-time synchronization of the source volume (real-time replication between two sets of remote media devices), and the same data is written to local and remote devices.
-
Asynchronous mirror function
Asynchronous mirroring is a non-real-time synchronization of the source volume (non-real-time replication between two sets of devices), the same data written to the main device after the success of the main equipment from the background timing synchronization to the backup device.

Automatic thin function
Automatic thin is a function that allows virtual allocation of capacity space to protect the user's initial investment. The initial actual purchase less actual capacity, but can be a virtual allocation of a larger capacity, follow the actual use of dynamic expansion。
-
Automatic tire function
Automatic tire is a balanced cost and performance, to provide users with the highest cost-effective product features. Configure a small number of high-performance layer SSD disk, the right performance SAS disk, and most capacity layer NL_SAS disk, to achieve business data flow between different levels of dynamic.
-
SSD Cache function
SSD Cache function is through the SSD as cache acceleration layer, improve system performance.
