[. . . ] User Manual TeraStation iSCSI TS-ITGL/R5 www. buffalotech. com v1. 0 Introduction Congratulations on your new TeraStation!Your TeraStation iSCSI is a huge block of iSCSI storage, ready to add to your server or PC via ordinary wired Ethernet connections. There are many ways to configure and use iSCSI storage products like the TeraStation. In this guide we give one example of configuring a simple iSCSI volume on a single workstation. [. . . ] Only use JumboFrame settings when operating in a Gigabit environment where all other clients support the same JumboFrame setting. Click Apply after making any changes. 20 Configuration GUI Disk Management (Drive Properties) This page shows the current properties of your hard drives and RAID Arrays. To change these settings, click on RAID Setup at left. 21 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 0 - All four drives are combined into one large, fast 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 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 the array, 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. This is how your TeraStation is set up out of the box. RAID 10 - Combines RAID 1 and RAID 0 for a fast, secure array. Half of the TeraStation's total capacity is used for redundant information. Buffalo Technology recommends RAID 5 for its excellent balance of efficiency and security. 22 Configuration GUI Disk Management (RAID Setup) 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. [. . . ] Cannot communicate with SATA chip (IC1).

Squeeze the tabs gently and swing the tray latch upward. The hard drive tray will now slide out. 41 Lower the drive carefully to the work surface. Gently push down on the two tabs to release the plug. 42 Pull the plug straight out to remove the drive. To remove the hard drive from its cage, set the assembly on a soft surface and remove these four screws. 43 Install a new hard drive by doing the same steps in reverse order: Begin by screwing the new hard drive into the cage. Plug the power/data connector into the hard drive. Slide the hard drive cage back into the TeraStation. Press the latch down to lock the hard drive cage in place. 44 Technical Specifications LAN Standards: Transmission Types: Access Media: Media Interface: USB Standard: IEEE 802. 3u 100BASE-TX; IEEE 802. 3 10BASE-T 1000Mbps/100Mbps/10Mbps; 100BASE-TX 4B/5B, MLT-3;10BASE-T Manchester Coding CSMA/CD RJ-45 USB 2. 0 Hi-Speed (HS) Full-Speed (FS) Low-Speed (LS) USB A Connector (2) Max: 480 Mbps (HS Mode) Max: 12 Mbps (FS Mode) UPS Compatible (Serial/USB connection) ~86W (Varies based on size) 6. 7" x 9. 3" x 12. 2" (170 x 235 x 310 mm. ) ~17. 6 lb (8 kg) (Weight varies based on size) 41° - 95° F; 20-80% non-condensing 45 USB Connector: Data Transmission Speed: UPS: Power Consumption: Dimensions: Weight: Operating Environment: Contact Information (North America) Buffalo Technology USA Inc. 11100 Metric Blvd, Suite 750 Austin, TX 78758 GENERAL INQUIRIES Monday through Friday 8:30am-5:30pm CST Direct: 512-794-8533 | Toll-free: 800-456-9799 | Fax: 512-794-8520 | Email: sales@ buffalotech. com TECHNICAL SUPPORT North American Technical Support by phone is available 24 hours a day, 7 days a week.
