HDD Hibernation
You can specify the period of time hard disks remain idle before entering HDD hibernation mode. During HDD hibernation, hard disks stop spinning, reducing power consumption and extending the lifespan of hard disks. You can specify different periods of time for internal hard disks and external eSATA/USB hard disks.
Note:
- HDD hibernation ceases upon access.
- Only certain external USB storage devices support HDD hibernation.
Why won't my DiskStation hibernate?
Please note that certain packages and services will prevent the DiskStation from entering hibernation mode and the system will exit hibernation mode two minutes before any scheduled task. For more information, please refer to this article.
System Hibernation (Available on DS213+ and DS413 only)
You can set the DiskStation to enter system hibernation one minute after hard disks start hibernating. System hibernation reduces the power consumption of the DiskStation.
During system hibernation mode:
- Power button enters breathing mode (slow on/off cycle). Other LEDs turn off.
- The power to the hard disks is cut off.
- CPU stops.
- The external fan stops.
- The LEDs on LAN ports turn off.
Note:
- Any SMB/CIFS broadcasting packet may prevent the server from entering system hibernation, including any Windows file browsers operating in the network. Should you wish to ignore CIFS broadcasting packets on entering system hibernation, please select Ignore broadcasting packets from Windows Explorer. Please be aware that once this option is selected, SMB/CIFS packets cannot be used to exit system hibernation. Attaching any USB devices will also prevent the server from entering system hibernation.
Deep Sleep
Deep sleep for expansion units can be enabled through the paired DiskStation interface. You can configure the expansion unit and paired DiskStation to idle for different periods of time. Therefore, the expansion units can be set to enter Deep Sleep while the paired DiskStation remains online.
During deep sleep mode:
- All LEDs of the expansion unit will be off.
- The power to the hard disks of the expansion unit will be cut off.
- The fan of the expansion unit will stop.
Note:
- Deep Sleep ceases upon access.
- To ensure normal operation when using the deep sleep function on an expansion unit, please slide its Auto/Manual switch on the back panel to Auto.
Auto Poweroff
You can specify the length of time for which the internal disk stays in hibernation before your DiskStation automatically powers off.
Note:
- You must enable internal HDD hibernation first.
- You must enable the WOL service first so that you can remotely power up your DiskStation.
- EDS14 does not support external eSATA drives, deep sleep mode, or auto poweroff.
