You’ll need the external address and port translation in the latter case. Each utility can access the NAS both from the LAN and from the internet. The software bundle includes the following utilities: DS finder, DS file, DS audio, DS photo+ and DS cam. It is easier, however, to install special client software which is freely available in the respective markets. The NAS’s web interface is available in Android and iOS optimized versions which help you access files in shared folders and do some setting-up. The AFP support allows using the backup tool Time Machine from Mac OS X. You can enable such features as a network recycle bin, local Master Browser, and logging of all file operations for SMB/CIFS. The DS411 provides data access via every popular networking protocol: SMB/CIFS, AFP, FTP, NFS, FTP/HTTP, and WebDAV. The default file system of the data partition is EXT4 and you can’t change that. They take about 2.5 gigabytes of disk space. The first two partitions are mirrored across all the disks, so the failure or removal of one disk won’t affect the whole system. Three partitions are created on hard disks when you install them into the NAS: system, swap and data. New in DSM 4.0, you can back up your iSCSI LUN to a local or network destination. In either case you will be able to implement fault tolerance. The new firmware supports iSCSI volumes which can be created as files on existing disk volumes or take up entire partitions. Refer to the manufacturer’s website for details on specific migration scenarios. Particularly, you can add disks to your RAID or replace them with larger-capacity ones. Synology offers flexible migration opportunities in terms of changing or expanding your RAID without losing data. The NAS supports the following disk configurations: JBOD, RAID0, RAID1, RAID5, RAID6, and RAID10. In the power management section you can make the HDDs shut down when not active. One such change is that you can now program a schedule for S.M.A.R.T. The new firmware doesn’t bring about many changes in terms of disk management. Password-guessing attempts can be blocked automatically. The integrated firewall can help protect the NAS on public or large networks. Having registered at, you can add several Synology NASes to your account and keep track of their status from that website. The MyDS Center service helps you monitor your NAS remotely. When using it for mobile access (via the DS file utility) and the Synology Cloud Station client, you can just enter your ID instead of the NAS’s network address. For example, the QuickConnect component of the ezCloud feature saves you the trouble of setting up your router, DDNS and other options manually. The NAS can automatically set up your home router to translate ports for necessary services.ĭSM 4.0 has greatly improved in terms of remote access and cloud computing features. About a dozen different DDNS services can be used, including Synology’s own. The DS411 has an integrated DDNS client for remote access. Up to 16 profiles can be defined but only one VPN connection can be active at any given time. You can use it to establish secure links to remote sites for backup copying or data exchange. One more new feature is the integrated VPN client for PPTP and OpenVPN. You can change the visual theme and port numbers for the web interface to work on. It offers an integrated help system and a wizard for inexperienced users. Its web interface is available in several languages and can be accessed via encrypted HTTPS. The NAS can also be set up quickly with default settings. When installing firmware, you can specify the name of your device, its IP address and administrator password. Of course, some options can be removed from the final release but our experience suggests otherwise. We won’t use the word beta to refer to the new firmware below. Some of its features won’t be available on “j” series models. By the way, DSM 4.0 is expected to be the last firmware version to be supported by Synology’s x08 series NASes due to performance requirements. The bundled software usually has to match the firmware, but you can use the latest DSAssistant with DSM 4.0-2166 beta. Take note that there is no official way of downgrading to an earlier DSM version. Synology having recently released its DSM 4.0 beta firmware, we want to describe its new features here but our tests were carried out with the latest stable version DSM 3.2-1955. If the HDDs have been transferred from another Synology NAS, you can keep user data intact. You launch the DSAssistant utility to find the NAS on the network, format your HDDs and install an operating system on them. The next thing you have to do with Synology NASes is install firmware to a dedicated disk partition.
