Storage Groups are designed to automatically replicate AppStacks and to distribute Writable Volumes across multiple datastores. You can also define a group of datastores that should all contain the same AppStacks.
Some of these group attributes will only apply when you use a storage group to distribute Writable Volumes. This would include things such as the template location and also the distribution strategy.
The distribution strategy setting controls how volumes are distributed across a Storage Group. There are two options for distribution:
Spread – This distributes files evenly across all storage locations. When a file is created, the storage with the most available space is selected.
