Explanation
Resolution: When Thin LUN is created, an initial allocated capacity can be set. After the creation is complete, the storage pool Pool only The initial capacity is allocated, and the remaining space is still placed in the storage pool. When the thin LUN has been allocated When the storage space usage reaches the threshold, the storage system will allocate a certain quota from the pool to the thin LUN. in this way Repeat until the full capacity of the Thin LUN is initially set. Therefore, it has a high storage space utilization rate.
