The system settings allow you to update firmware (the NAS can check out for firmware updates and download them from the internet), reset the configuration, choose a language for the web interface and admin notifications, and set the internal clock up. New in this firmware version, you can back up your NAS configuration including its services and later restore all or some of the settings.
DSM 4.0 has been improved in terms of admin notifications. Besides conventional email and SMS notifications (the latter is a paid service), Windows Live Messenger and Skype are available as communication channels. Mobile gadgets are supported directly in push mode if you install the DS finder utility on them (currently compatible with iPhone/iPad products only). Considering so many ways for the NAS to communicate with its administrator, the option of assigning different types of notifications to different communication channels may come in handy. For example, you can receive emergency notifications via SMS and Skype and have routine ones (like a backup complete notification) sent to your email address.
You can enable a schedule for the NAS to work by in the power management options. The DS411 supports Wake-on-LAN. It can get both the internal and USB-connected disks down to sleep and be woken via DSAssistant or other compatible utilities.
There are two health-checking features available: system info panel and resources monitor. The former offers you data about the current status of the system such as model name, firmware version, temperature, network addresses, extra services, disk usage, current connections (you can disable any of them), and detailed logs. If necessary, every file operation via Windows network, FTP, WebDAV or File Station can be logged. Syslog servers are supported, too.
The usage of CPU, memory and network controller resources is shown in real-time graphs. You can even view detailed information about how much CPU and memory resources the currently running processes use.
