Priority
: The options are High, Medium, and Low. The priority compares to other
volumes. Set it as High if the volume has many I/O.
Background I/O Priority
: The options are High, Medium, and Low. It will influence
volume initialization, rebuild, and migration.
Cache Mode
: The options are Write-through Cache and Write-back Cache. Write-back
optimizes the system speed but comes with the risk where the data may be inconsistent
between cache and disks in one short time interval.
Volume Type
: The options are RAID Volume, Backup Volume, and Read-only Volume.
RAID Volume is for general RAID usage and Backup Volume is for the target volume of
local clone or remote replication. If the volume capacity in thin provisioning exceeds the
threshold, it will enter a read-only state.
