Downtime

  • The upgrade of a single-node system takes the system offline for up to 25 minutes, during which I/O is interrupted.

  • Upgrading an HA pair is non-disruptive and I/O is uninterrupted. During this non-disruptive upgrade process, each node is upgraded in tandem to continue serving I/O to clients.
