Although the hardware platform employed in this NAS supports a lot of peripheral interfaces, the Ultra 2 only offers two USB 2.0 ports based on the chipset and one USB 3.0 port based on an external controller. As with most other NASes, you can use these ports to connect external disks (flash drives and HDDs), printers and UPSes. USB hubs are supported. You can connect external disks with multiple partitions formatted in FAT32, EXT2/3/4 and NTFS. If necessary, you can partition your external disk in FAT32 or EXT3 via the web-interface. Each partition is represented as an individual network resource. You can change its name and specify its access rights. There is an option for automatic copying of files from connected external disks to a specified folder on the NAS.
The print-server uses Windows’ standard protocols or IPP. Only printing is available with all-in-ones.
The list of compatible UPSes is mostly made up by products from APC. The Ultra 2 can work as a network UPS server: you can use a single battery for multiple devices, so that all of them could be shut down safely in case of a power failure.
You can check out the status of the NAS by the colorful indicators in the bottom of the window. The home page of the web-interface offers such information as device name, network addresses, serial number, firmware version, memory amount, and disk usage. There is another status page reporting such parameters as HDD temperature, SMART data, fan speed, system temperature, and UPS status. The Ultra 2 can shut down automatically if the HDDs get too hot or malfunction.
The NAS has a common log for all kinds of events without offering the option of quickly filtering them. If you want to examine an exceptional situation, you can click a special link to save a few dozen system reports.
The Ultra 2 can notify the administrator about certain events to up to three email addresses. You can use the NAS’s own email server for that.
The administrator is the only user who can set up the NAS’s parameters. The password recovery system is quite complex with a secret question and answer that are verified via email. So, you’d better not forget your password or at least check out how this service works.
There are standard options for setting up the internal clock, updating the firmware (this can be done via the Internet without a PC), and resetting/saving/restoring the settings. The language codepage parameter isn’t really necessary nowadays as most computer systems already support Unicode.
The x86 platform usually features flexible power management options. Indeed, the Ultra 2 can turn off the disks and work by a weekly schedule. It supports WoL and uninterruptible power supplies (both local and network-attached). There is a special page in the web-interface for turning off or rebooting the NAS via network. On the same page you can enable a file system test to run on the next reboot.
