Disk Group Alignment
One of the attributes of the disk group is the block alignment, which represents the largest block
size supported by the disk group. The alignment constrains attributes of the objects within the disk
group, such as:
◆ Subdisk; how subdisks are positioned on the drive (offset), and their size granularity (length)
◆ Plex offset
◆ Volume length
◆ Log length
◆ Stripe width
The disk group alignment is assigned at disk group creation time (see “Maintaining Your System”
on page 21).
