  • Page 9: Storage Policies

    2 STORAGE POLICIES You can configure the TowerRAID TR4UTP/TR4UT-BP 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.

  • Page 10: Clone Mode

    TR4UT / TR4UT-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 11: R0 Mode

    TR4UT / TR4UT-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 12: 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 13: 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 14 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 INSTALLATION 3.1 BEFORE INSTALLING Please unplug the power cable, and switch the VAC to the correct position (For example, 115 for Japan, and 230 for UK) before installing. It may exposure to strong magnetic fields and malfunctions or damage. 3.2 INSTALLING HARD DISK DRIVE Please refer below procedure to complete the HDD installation.
