Hitachi Unified Storage VM Product Overview Guide
System management unit
The system management unit (SMU) in the file module (HNAS) system is
equivalent to the service processor in the block module system. It provides
administration and monitoring tools, supports data migration and
replication, and acts as a quorum device in a cluster configuration. Although
integral to the system, the SMU does not move data between the network
client and the servers.

external SMU is attached. All cluster configurations require an external
SMU.
