Use cases
Use cases to consider.
Replace older device sets that contain outdated hardware, smaller device capacity, and so on.
Resize existing device sets to take advantage of newly added capacity.
Storage Pools should be expanded when projections of ingest for current pools suggest they will near their capacity. Reallocation takes time. Plan to start an expansion such that the reallocation can move data off the original Device Sets before they run out of capacity.
This feature replaces the current Merge Storage Pool function.
A case for creating new Storage Pools
While Storage Pool Expansion eliminates the requirement to form new Storage Pools to expand the system, it does not entirely eliminate all justifications for creating new Storage Pools.
In situations with differing storage requirements (for example, different physical locations, different levels of physical security, different IDA configurations, different users, and so on), you should create different Storage Pools to meet the different storage needs.
