I think what you mean is: Can the unused capacity of one device be used by another device? The answer is "maybe" :-) If there is no over-provisioning then  every TDEV will have access to its full capacity. If there is over-provisioning then a device MAY not get its full allocation.
Hi, When i create a LUN as thin provisioning and if this will never fill to the maximum capacity then the unused size is used to create other LUN?I mean inside SAN. tnx
thin provision
