  • Total2: Total capacity of the internal volume. The expanded capacity appears for parity groups on which accelerated compression is enabled.

  • External: Capacity of all of the parity groups in the external volume.

  • Free1: Free space capacity of the external volume.

  • Total2: Total capacity of the external volume.

Number of Drives

  • SSD: Displays the number of SSDs.

  • SAS: Displays the number of SAS drives.

  • Total: Displays the total number of drives.

Format/Shredding Task Status

Formatting n %: Displays the progress of the format task.

Preparing Quick Format n %: Displays the progress of the quick format preparing.

Shredding n %: Displays the progress of the shredding.

Verifying n % (x / y parity groups): Displays the progress of the verifying. n represents the progress of the verifying. x represents the number of parity groups that are completed of verifying. y represents the number of all parity groups that are to be verified.

Blank: States that the format, shredding, or verifying is not being performed. If the configuration of the storage system is being changed, this field is also blank because the information cannot be collected.

Notes:
