Enabling Eco Mode on the ETERNUS Disk storage system can control ON/OFF of disk drive power (or spindle rotation) using the Storage Cruiser functions. For example, the Storage Cruiser commands can power ON a disk drive as backup destination at backup and power it OFF on completion of backup.
It is possible to save power consumption under the following operations:
Backup management
Snapshot type high-speed backup (OPC) with no access to the backup volume for a long period of time.
Suspend/Resume functionality of synchronous type high-speed backup (EC) with a long suspend time.
Replication management
Snapshot type high-speed replication (OPC) with no access to the replication destination volume for a long period of time.
Suspend/Resume functionality of synchronous type high-speed replication (EC, REC) with a long suspend time.
An overview of the system structure is as follows.
