Your system creates volumes as thin volumes.
When a volume is created, the Resource Balancer determines on which appliance the volume is provisioned, although you can select the appliance from the drop-down list. If the Resource Balancer is choosing a default appliance, it does not choose a volume has been mapped to a specific host or host group. In such cases, the volume is created only on an appliance that sees this host or host group.
Volumes can be between 1 MB and 256 TB in size.
There is no redirection between appliances in a cluster, meaning that I/O is sent to one of the two nodes that contains storage for the volume.
