InDell Unity XT dynamic pools, when new drives are added to an existing pool, the system automatically integrates these drives into the pool. However,Unity XT dynamic pools only use the capacity of new drives up to the size of the smallest drive in the pool(a concept known ascapacity equalization).

✅What happens here?

The original pool was created with1.92 TB SSD drives.

The administrator adds4 x 3.84 TB SSD drivesto the same pool.

Because the pool’s smallest drive is1.92 TB, the system uses only1.92 TBof capacity from each of the new drives.

The remaining1.92 TBof the new drives’ capacity isnot utilizedin the dynamic pool.

✅Key Takeaways:

This behavior ensures uniform capacity usage across all drives in the pool, maintainingRAID group balance and data distribution.

To fully leverage the 3.84 TB capacity, the administrator would need to create anew poolusing only the larger drives.
