Secure Shell (SSH) software is a client-server protocol that can be used from the IBM® System Storage® Productivity Center or from a host server to enable you to control the SAN Volume Controller through a command-line interface (CLI).
SSH provides a secure communications channel between systems. You can configure SSH to use a key pair (a private key and a public key) to establish the secure connection to a remote system. If you want to create an SSH connection to a server using an SSH key pair (such as to the SAN Volume Controller cluster), you must place the public key on the server.
