Allocation Record is similar to LVM's physical extent (PE)
Storage Chunk is similar to LVM's logical extent (LE)
Storage Chunk1+Storage Chunk2+Storage Chunk3+... is similar to LVM's volume group (VG)

And filesystem use aggregation of Storage Chunks directly to store metadata and
data on them.

I'm right?
