The advanced RAID configurations & hot-swap capabilities are included to give RAID performance, protection & reduced rebuilding time. Moreover, the dual OS embedded on the DOM architecture ensures the system will boot up. If one of the two operating systems fails, the healthy operating system will boot up & operate normally while repairing the failed operating system. The dual Gigabit LAN ports can also be configured for failover which allows the NAS server to sustain the failure of one network port & still provide continuous services. Setting up local or remote access with the TS-879U-RP is painless & does not require any IT skills. All setup processes have been simplified so that most of the process is either automatic or can be completed by an installation wizard. The user-friendly web GUI allows administrators to easily manage the NAS so there is no need for an extensive knowledge of complex commands. Simple management tools such as instant SMS/ Email alert, the hard drive S.M.A.R.T. (Self-Monitoring, Analysis & Reporting Technology) feature, & system resource monitor are provided to keep administrators up-to-date on their NAS at all times. The TS-879U-RP features Intel Core i 3 Processor, 2GB DDR3 memory, 10 Gigabit network capability, & 6 Gb/s SATA.
