Virtual Disk Drive (VDD) adds flexibility to storage expansion along with ease of management
The unique "Virtual Disk Drive" adds flexibility to expand the capacity of NAS. By using the built-in iSCSI initiator, the NAS can connect to other iSCSI targets on the network and turn them into virtual disks, which become multiple single volumes on the NAS. Up to 8 virtual disks can be stacked. The NAS serves as the storage stack chaining master. The user only needs to connect to this single entry (QNAP NAS) and is able to reach and use all the iSCSI LUN on the network.

Redundant Power Supply
The TS-459U-RP is equipped with two power supply units, each of which is capable of supplying the power for the entire NAS independently. If one of the units fails, the other one will take over to supply the power to ensure continuous operation of the NAS. You can replace the failed power supply unit without turning off the server.

Hard Disk Standby
The hard disks can be configured to enter standby mode if there is no disk access within the specified period.

Scheduled Power on/ off
The flexible scheduled power on/off feature is provided on the NAS for you to manage the NAS server's up time according to the working hours.

UPS Support
The NAS supports the majority of USB UPS devices (usbhid-ups supported) which enables the users to store the data in time and avoid critical data loss when power outage occurs during data transfer. It also supports advanced stand-by mode setting that you can set the time for the server to enter standby mode when an abnormal AC power supply is detected. When the power resumes, the server resumes to the operation status before the power outage.

Auto Power on After Power Loss
You can configure the NAS to turn on/ off when the AC power resumes after a power loss.
