STORAGE POOL: A logical grouping of OSDs in CEPH, allowing administrators to define specific performance and redundancy characteristics for different types of data.
Analogy: Think of storage pools as different sections within the library, each tailored for specific types of books – like a “high-demand” section for popular novels and an “archive” section for less frequently accessed materials.
Why It Matters: Storage pools enable fine-grained control over data placement, performance optimization, and the application
of different data protection schemes.
