Description

Data storage nodes (Member Nodes or Coordinating Nodes) will go offline for various reasons - maintenance, hardware failure, decommissioning, etc. The infrastructure built by DataONE must not be adversely affected by such events.

Rationale

This is a requirement of content persistence (#410).

No systems have 100% uptime, and so we should design and plan for failure of MN or CN nodes.

Fit Criteria

  • XX% of all Data remains available if XX% of member nodes go offline
  • The infrastructure remains functional if two CNs go offline
