SSH

All nodes in the IBM Storage Ceph cluster use SSH as part of deploying the cluster.

On each node:

  • A cephadm user exists with password-less root privileges.

  • The SSH service is enabled and by extension port 22 is open.

  • A copy of the cephadm user’s public SSH key is available.

Important: Any person with access to the cephadm user by extension has permission to run commands as root on any node in the IBM Storage Ceph cluster.
