Why learn RAIN — Redundant Array of Independent Nodes?

Distributes redundancy across independent system nodes.

Where it came from

Node redundancy needs an appropriate data-placement and failure-domain design.

• Memory aid (a learning cue, not the expansion): RAID-like resilience moves from disks to Nodes.

Build your understanding

Work through these exercises in order. Try the task before opening a reference.

1. Without looking, expand RAIN: Redundant Array of Independent Nodes.
2. Recall this memory aid: RAID-like resilience moves from disks to Nodes.
3. Explain the practical use: Distributes redundancy across independent system nodes.
4. Explain this distinction: Node redundancy needs an appropriate data-placement and failure-domain design.
5. Identify RAIN in a device specification, architecture diagram, or system inventory.
