thick LUN, is distributed equally across the disks in the pool on
which you create the LUN This behavior changes once data is added
from hosts and additional disks are added to the Pool Incoming data
will be added to the new disks only until all disks areequally
populated again Capacity of a thick LUN, is the same as the user
capacity that the servers operating system seesA thick LUN uses
slightly more capacity than the amount of user data written to it
due to the metadataA thick LUN can never run out of space.Copyright

systems with the Thin Provisioning enablerCompetes with other LUNs
in the pool for the pools available storageCapacity of the thin LUN
that is visible to the server is independent of the available
physical storage in the poolA thin LUN can run out of disk space if
the pool to which it belongs runs out of disk spaceA thin LUN uses
