Introduction to the SMU400

The SMU400 is a 1U rack mounted device, used to manage the servers and clusters of the

Hitachi NAS Platform and the Hitachi HUS File Module storage systems.

HDS does not support component replacement, and the entire SMU should be replaced in case

of hardware failures.
