Dynamic Pools on EMC Unity All Flash storage
For Unity All Flash storage, its architecture of Storage Pool is different with Unity Hybrid storage (eg, Unity 350F). This new Pool technology is called “Dynamic Pools”. The following is the difference between Traditional Pools and Dynamic Pools.
Dynamic Pools do not require Hot Spares
If a drive within a Dynamic Pool fails, Spare Space within the Pool is utilized
Spare space will be handled automatically when a Pool is created or expanded
Spread I/O load over all drives more frequently than traditional pools
More drives are engaged in the rebuild process
NOTE: Supported on All Flash physical hardware only
