3.4 Key Points for Cluster Configurations (1/4)
Cluster operation with cluster operation software is supported to increase the system availability.
For details, refer to "Chapter 1 Product Overview" in "General Description".
Relationship Between Redundant Configurations and Reliability

Firm reliability of the cabinet
 Component redundancy
(PSU, FAN, MMB, IOU, and so on)
Redundancy of the power
supply, fan, and so on
(Countermeasures against
operation failure)
