User manual BUFFALO TS-2.0TGL

[. . . ] User Manual TeraStation Pro TS-TGL/R5 www. buffalotech. com v2. 2 Introduction Congratulations on your new TeraStation!This user manual is intended to assist you in configuring it. Because we're constantly updating our product, the images and text in this manual may vary slightly from the images and text displayed by your TeraStation. These changes are minor and should not affect the ease of setup adversely. [. . . ] RAID 1 (mirroring) - Hard drives (or spanned pairs of hard drives) are arranged in mirrored pairs. Each half of the pair reads and writes exactly the same data. This costs you half the total capacity of your TeraStation, but provides excellent redundancy. If a hard drive fails, the mirror continues to supply data, so you may work on normally. You may replace the damaged or defective drive at any time, and normal RAID 1 mirroring will then be automatically restored. RAID 5 (parity) - All drives in a RAID 5 array reserve part of their data space for parity information, allowing all data to be recovered if a single drive fails. The parity information takes up about one hard drive's worth of space, so if you set up all four drives in the TeraStation as a RAID 5 array, your usable capacity will be about 3/4 of the total capacity of the TeraStation. RAID 5 is an excellent compromise between efficiency and security. If a single drive fails, no data is lost. After the damaged or defective drive is replaced, your TeraStation will automatically restore all data to the new drive and resume normal RAID 5 operation. This is how your TeraStation is set up out of the box. Buffalo Technology recommends RAID 5 for its excellent balance of efficiency and security. Advanced Settings Disk Management (RAID Configuration) This page shows your current RAID arrays. You may delete old arrays or create new ones by clicking on the underlined RAID Array # under RAID Array Configuration. The RAID Scanning Settings set a specific time for the TeraStation to scan and inspect its RAID arrays. It is recommended to set a time where the TeraStations usage will be minimal (perhaps the middle of the night). TeraStation will be significantly slower while the RAID scan occurs. Begin Immediate RAID Scan specifies the TeraStation to run a RAID Scan immediately after pressing Apply. You may also disable RAID Array Error Detection Response from this page. Normally, this is set to automatically shut down the RAID array when an error is detected. Though it is not recommended, you may disable that behavior by selecting Disable. NOTE: TeraStation has four internal hard drives. Before creating a new RAID array, you may have to delete one or more pre-existing RAID Arrays to clear up the hard drives for your new one. [. . . ] Installed on your PC, it allows you to access each of the TeraStations on your network. Click Refresh List to get tabs for each of your TeraStations. Each tab shows the Host Name, Workgroup, IP Address, and Subnet Mask of the associated TeraStation, as well as the version of firmware it's running. With a TeraStation's tab selected, you can click on the View Shares button to go directly to its root share. [. . . ]
