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, REC) with a long suspend time.
Replication management
Snapshot type high-speed replication (OPC) with no access to the copied volume as the backup destination for a long period of time.
Suspend/Resume functionality of synchronous type high-speed replication with a long suspend time.
An overview of the system structure is as follows:
