Storage Pool is a logical aggregation of physical disks or capacity from which volumes or storage spaces are allocated.
Simple definition
Storage Pool is a logical aggregation of physical disks or capacity from which volumes or storage spaces are allocated. It belongs to the Storage vocabulary and is useful when reading architecture diagrams, product documentation, logs, or administration procedures.
What is it used for?
Its main purpose is to pool capacity and resiliency before creating volumes consumed by servers or applications. The practical value depends on the surrounding architecture, security model, and operational requirements.
How does it work?
The system aggregates member devices, tracks their state, and distributes allocations according to pool technology and selected resiliency.
Key points
- Scope: A logical aggregation of physical disks or capacity from which volumes or storage spaces are allocated.
- Operational goal: Pool capacity and resiliency before creating volumes consumed by servers or applications.
- Implementation: The system aggregates member devices, tracks their state, and distributes allocations according to pool technology and selected resiliency.
Points to watch
Document topology and dependencies before changes; a pool, tiering, or multipath mistake can cause access loss or severe degradation.
In short
Storage Pool = a logical aggregation of physical disks or capacity from which volumes or storage spaces are allocated. Use it when you need to pool capacity and resiliency before creating volumes consumed by servers or applications.
