User manual BUFFALO TS-TGL : TERASTATION PRO

[. . . ] User Manual TeraStation Pro TS-TGL/R5 www. buffalotech. com v2. 5 Introduction Congratulations on your new TeraStation!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. As time passes, future user interfaces, updated software, and later versions of this manual may be freely available for download at our web site: http://www. buffalotech. com. [. . . ] RAID Spanning is fast and efficient, but with no redundancy, if one hard drive fails, all data on the TeraStation is lost. RAID 1 (mirroring) - Hard drives (or spanned pairs of hard drives) are arranged in mirrored pairs. 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 (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. 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. Buffalo Technology recommends RAID 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). 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. 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. This will destroy all data currently on the disks, so back up any important data before deleting RAID arrays. Whether you want to clear out an old array or create a new one, begin by clicking on the array's underlined RAID Array #, under Name. 0 Advanced Settings Disk Management (RAID Configuration) A configured RAID array may be deleted by pushing the Delete RAID Array button. This will free up all hard drives listed under Disk Structure. To configure an unconfigured array, put checks next to the hard disks you want included in the array (under Disk Structure) and choose your RAID mode. When it's finished, a Disk Scan will run, this may take several hours to complete; performance will be slow during the Disk Scan. 1 Advanced Settings Disk Management (Disk Check) When RAID Configuration is done, you'll see this screen. To configure a new array, click on RAID Array # and go back to the bottom of page 31. [. . . ] Clicking the Setup pulldown menu and selecting Browser Management takes you to the browser management tool that we began exploring on page 24. And clicking Setup and choosing Modify IP Address takes you to the following screen . . TeraStation Client Utility IP Address Setup Here, you may enter your IP Address and Subnet Mask manually, or enable your TeraStation to acquire them automatically from a DHCP server. Press OK when you're done. Troubleshooting If TeraStation encounters a disk error, it will be reported in the TeraStation status on the top of any of the Web-Based configuration screens. [. . . ]
