Dell Unity XT Dynamic Pools are constructed from the physical drives within a storage pool. Each drive is partitioned into 1 GB segments called drive extents. To create RAID sets and distribute data, these 1 GB drive extents are further subdivided into smaller, fixed-size chunks called slices. The architectural size of each slice in a Dynamic Pool is 256 MB. These slices are the fundamental building blocks used for RAID extent creation and data placement across the drives in the pool.

B. 128 MB is an incorrect value for the slice size in Unity Dynamic Pools.

C. 64 MB is an incorrect value; this size is more commonly associated with traditional RAID Group LUN private space, not Dynamic Pool slices.

D. 512 MB is an incorrect value for the slice size in Unity Dynamic Pools.
