User manual BUFFALO HS-DTGL : TERASTATION HOME SERVER

[. . . ] User Manual TeraStation HS-DTGL/R5 www. buffalotech. com Rev 1. 4 Introduction Congratulations on your new TeraStation!This user manual is intended to assist you in configuring it. If you run into difficulties or need additional help, feel free to contact our 24/7 Technical Support at (866) 752-6210 (USA & Canada only). Technical Support in Europe is available between the hours of 9am - 6pm (GMT) Monday through Thursday and 9am-4:30 pm (GMT) Friday for this product. [. . . ] 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. 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. 29 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. 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 clicking Disable and then Apply under RAID Array Error Detection Response. Note that your 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. This will destroy all data currently on the disks, so back up any important data before deleting RAID arrays. [. . . ] This affects Admin Password, Ethernet Frame Size, and IP Address. If the Remain option has been selected on the screen below, then the Admin Password will not be reset when the INIT button is held down. Pressing Apply for Restore Defaults from Maintenance/Initialization resets Admin Password, Hostname, TeraStation Description, NTP Settings, Workgroup Settings, Access Restrictions, User Settings, Group Settings, Mail Notifications, UPS Settings, Disk Sleep, and Disk Backup. If you select the Remain option for Admin Password and then click Apply, the admin password will no longer be reset when the INIT button on the TeraStation is held down. 63 Advanced Settings System Status (System Information) This page shows you the System Information for your TeraStation. 64 Advanced Settings System Status (USB Details) This page shows you details on USB hard drives and printers plugged into your TeraStation. 65 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. 66 Advanced Settings System Status (Network Information) This page shows you the System Information for your network connection. 67 System Status User Access Status This page shows you the current status of all users on the system. 68 TeraStation Client Utility This is the TeraStation Client Utility. Installed on your PC, it allows you to access each of the TeraStations on your network. [. . . ]
