CES node (protocol node)

Only nodes that are designated as CES nodes can serve integrated protocol function.

Nodes in the cluster can be designated to be CES nodes by using the mmchnode --ces-enable Node command. Each CES node serves each of the protocols (NFS, SMB, Object, Block, HDFS namenode) that are enabled. CES IP addresses that are assigned for protocol serving can failover to any of CES nodes that are up based on the configured failback policy. CES functionality can be designated only on nodes that are running on supported operating systems, and all the CES nodes must have the same platform (either all Intel or all POWER® Big Endian).

For information about supported operating systems and their required minimum kernel levels, see IBM Storage Scale FAQ in IBM® Documentation.
