Firmware Update: Synology DSM 6.0.2 build 8451

Synology has released version 6.0.2 of Disk Station Manager. DSM is the management software that runs on several of the company’s NAS products. The Disk, Cube and Rack Stations offer more than just extra storage space. For example, backups of all clients on the network can be made and files can be downloaded via http, ftp, bittorrent, usenet and emule, so that, for example, energy-hungry PCs can switch off at night while the download just comes in. Furthermore, audio and video files can be streamed over the network via the built-in iTunes server, a dynamic website can be hosted using PHP and MySQL and the device can act as a print server.

To be able to install version 6.0, at least version 5.2 must be present. Furthermore, it is only suitable for the NAS models whose type number ends with 11 or higher.
