  • Page 4: Welcome

    1 WELCOME 1.1 INTRODUCTION Thank you for choosing EliteRAID ER104UT(-B) storage appliance. It is a hardware RAID solution for digital home and small office storage appliances. Features of the EliteRAID ER104UT(-B) include advanced RAID modes. Simply connect the appliance with an appropriate USB or eSATA cable to the USB host or PCIe 1x controller card. eSATA bracket cable is provided to connect to motherboard if no PCIe slot avaliable.

  • Page 5: Precaution

    1.2 PRECAUTION Please read the safe precautions carefully before you using EliteRAID ER104UT(-B) storage appliance. Ensure that you use the product correctly according to the procedure described in this guide. The following safety precautions are intended to remind you to operate the product safely and correctly. Please read and ensure that you understand them before you proceed to the other sections of this guide.

  • Page 6: Sata Features

    1 host port (eSATA or USB) to 4 Serial ATA hard disk drives. Compatible with SATA Gen1 and Gen2 host controllers. Compatible SuperSpeed USB 3.0 specifications, backward compatible with USB 2.0. Embedded fast Storage Processor. Ultra-fast 3Gbps host and device port capability. Greater than 200MBps sustained reads in R0 mode (limited by drives and host controller).

    1.5 SYSTEM REQUIREMENTS 1.5.1 PC SYSTEMS • Intel Pentium-III 500MHz equivalent or faster • Windows XP, Windows Vista, Windows 7 RC2 with the latest Service Packs • CD-ROM drive • 64 MB of RAM (minimum) • 250 MB of free disk space •...

  • Page 8: Storage Policies

    2 STORAGE POLICIES You can configure the EliteRAID ER104UT(-B) storage appliance to use any of the following storage policies to map the appliance’s physical hard drives to virtual drives that are visible to the host computer. The virtual drives are called volumes. The host operating system treats each volume as if it were a single physical drive.

  • Page 9: Clone Mode

    ER104UT(-B) It is also possible to create a LARGE volume using only a single hard disk drive connected to Port 1. However, it is not possible to expand an existing LARGE volume by adding another hard disk drive and still preserve any existing data on that volume.

  • Page 10: R0 Mode

    ER104UT(-B) 2.4 R0 MODE The R0 MODE storage policy distributes access across all hard disks. R0 MODE presents the best data speed but no data redundancy. R0 MODE storage policy accelerates hard disk drive operating speed by using many disks in parallel. Hard disk drive data segments are written to different disks simultaneously which increases performance while sacrificing data redundancy.

  • Page 11: R10 Mode

    Although the volume remains available during the rebuild process, the volume is susceptible to data loss through damage to the remaining drive until redundancy is restored at the end of the rebuild and verification process. Host access takes precedence over the rebuild process. If you continue to use the R1 volume during the rebuild, the rebuild process will take a longer time to complete, and the host data transfer performance will also be affected.

  • Page 12: R3 Mode

    2.7 R3 MODE The R3 MODE storage policy requires a minimum of 3 drives to implement. The R3 MODE adds fault tolerance to drive striping by including parity information with the data. R3 MODE dedicates the equivalent of one drive for storing parity stripes.
  • Page 13 stripes. The data and parity information is arranged on the drive array so that parity is written to all drives. There are at least 3 members to a virtual R5 volume. The following example illustrates how the parity is rotated from drive to drive. The R5 MODE uses less capacity for protection and is the preferred method to reduce the cost per megabyte for larger installations.

    3 CONFIGURATION 3.1 CONFIGURATION PREREQUISITES 3.1.1 SATA HOST CONNECTIONS This guide assumes that you have already attached the EliteRAID ER104UT(-B) to a host computer that has been installed with the R622 HBA (Host Bridge Adapter) or another SATA HBA with Port Multiplier (PM) support. If you use a host controller that does not provide Port Multiplier support (Such as Intel ICH): •...

    3. The following message then appears: “Safe to Remove Hardware”. You can now safely disconnect the device from your computer. Note: If your host USB adapter does not support this feature, the device should be disabled using the Device Manager or your system should be shut down cleanly and powered off before disconnecting the USB device. 3.3.2 MACINTOSH SYSTEMS You must un-mount the hard disk drive by dragging the hard drive icon to the trash before disconnecting it or...

    4 PARTITIONING VOLUMES 4.1 PARTITION A VOLUME 4.1.1 WINDOWS SYSTEMS Note: Before repartition a volume, back up your data and delete previously defined partitions. 1. Right-click the My Computer icon on your desktop and select Manage from the pop-up window. 2.
  • Page 21 checked and click OK. The disk should now be marked as a Basic disk. If a disk appears as “Dynamic”, right-click the disk icon, and select Revert to Basic Disk. Within a few seconds, the disk should be marked as a Basic disk. If a disk is marked “Not Initialized”, right-click the disk icon and select Initialize Disk.
  • Page 22 4. Click Next to start the Partition Wizard. 5. Select the Primary or Extended option and click Next.
  • Page 23 6. Specify the partition size. By default, the partition occupies the entire volume. Click Next. 7. Assign a drive letter or mount path and click Next.
  • Page 24 8. Name and format the partition and click Next. 9. Review the file system settings and click Finish to create the logical partition.

    10. Repeat steps 1 through 9 to partition any remaining disks. 4.1.2 MACINTOSH SYSTEMS Note: Before reconfiguring a volume, back up your data and drag the old drive to the trash to un-mount previously partition. After you configure and partition the new volumes, restore the backed-up data to the new configuration.
  • Page 26 2. Select a configured disk and click the Partition tab. This procedure illustrates the LARGE Storage Policy configuration, which concatenates the capacity of all hard drives connected to the TERA BOX SATA RAID III. 3. Select 1 Partition from the Volume Scheme drop-down list. 4.
