User manual BUFFALO TS-1.0TGL

[. . . ] User Manual TeraStation Pro TS-TGL/R5 www. buffalotech. com v2. 2 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. [. . . ] The Authentication Setup fields will be automatically filled out, so no input is needed there. 7 Advanced Settings Disk Management (Drive Properties) This page shows the current properties of your hard drives and RAID Arrays. To change these settings, click on RAID Configuration at left. 8 Note on RAID Arrays TeraStation uses RAID ("Redundant Array of Independent Disks") technology to control the four hard drives in your TeraStation. RAID may be configured several ways: RAID Spanning - All four drives are striped into one large drive, giving the maximum capacity for your TeraStation. This size is the one listed on your TeraStation's box and shows the total capacity of the TeraStation with no data used for redundancy. 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 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. 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 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). 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 cannot be undone. 57 System Status (System Information) This page shows you the System Information for your TeraStation. Firmware updates are occasionally available from www. buffalotech. com for the TeraStation Pro. Your router, switch, or hub should pass through ports 8873 and 22939 for this to work (most do). 58 Advanced Settings System Status (USB Details) This page shows you details on USB hard drives and UPSs plugged into your TeraStation. 5 Advanced Settings System Status (Drive Properties) This page shows you the properties of all hard drives and RAID arrays in and attached to your TeraStation. 60 Advanced Settings System Status (Network Information) This page shows you the System Information for your network connection. 61 System Status User Access Status This page shows you the current status of all active users on the TeraStation. It also shows users connected remotely via the FTP Server. 6 System Status Log Information This page displays system log information. [. . . ]
