Design decisions and limitations

Expand across physical sites
Because data is reallocated between Slicestor® Appliance devices during system expansion, it is preferred that the new Slicestor® Appliance is physically located in the same sites as the existing sets.
Health of Slicestor® Nodes
The system should be in as healthy as possible before performing expansion: replace any bad drives, perform any evacuations, and so on.
Compatibility with old clients
All Accesser® Nodes must upgrade to ClevOS version 3.6 before using Storage Pool Expansion, otherwise they cannot access Vaults in newly expanded Storage Pools.
Merge storage pools
Multiple original Storage Pools cannot be collapsed into a single Storage Pool.
