Security

The security menu provides several options to properly protect your server. You should examine all these security options if you plan on storing sensitive data.

Hardware

These options allow you to configure the NAS's hardware functions. The most important ones are HDD Standby, Write Cache, which nets you increased write performance, and the Smart Fan option, which allows you to set the fan to auto-mode or a customized fan profile.

Power

ErP, or EuP, stands for Energy Using Product and is a directive developed by the European Union. It is a measure of how much power a system consumes, and its purpose is to protect the environment by regulating how much energy goes to waste. The ErP Lot 6 2013 directive asks for less than 0.5 W power consumption in standby and is obligatory for every PC system or NAS sold in the EU. The TS-451+ will consume less than 0.5 W in standby with EuP enabled, but enabling it will disable Wake on LAN, AC power resumption, and all scheduled power settings.

Firmware Update

The QTS OS features a live update function that can automatically check for newer OS versions when you log into the administration interface. You can also join the QTS beta program to receive beta firmware. The update is a very straightforward procedure during which you will not loose the data stored on the NAS; however, QNAP does prompt you to back it up before proceeding with a firmware update.

External Devices

All connected external storage disks, USB printers, and UPS devices can be configured through these options. You can format external storage disks into all popular formats, including EXT4, NTFS, and FAT32.

System Status

The System Status window includes the resource monitor and a summary of the system and its hardware, your network's status, and all running system services.


CPU-, HDD-, and System temperatures can be seen in the Hardware Information tab of the System Status window. There is also a widget you can drag to the desktop. It will keep track of system temperatures.
