7. Configuration

7.1 Preparation

  1. SATA host connection

This installation guide assumes that you have already connected the 8-BAY RAID STATION to a SATA or eSATA host controller with Port Multiplier (PM) support.

Note:

If you use a host controller that does not provide Port Multiplier support (Such as Intel ICH), the CLEAN mode is not available when configuring the 8-BAY RAID STATION. Only one disk is available on the host computer.

  1. USB host connection

If you are connecting your 8-BAY RAID STATION using an USB connection to your host, the USB port should be compliant with USB2.0 or 3.0.

7.2 Changing the host connection

The 8-BAY RAID STATION supports both USB and eSATA host connections, although only one connection can be attached at the same time.

If it becomes necessary to switch the host connection between eSATA and USB, the host computer system and the 8-BAY RAID STATION should both be powered down prior to changing the host connection, in order to avoid data loss. After changing the host connection, both devices can be powered-on again to continue operation with the new host connection.

7.3 Disconnecting an USB device

USB3.0 external devices provide support for Plug&Play connection, so that your USB storage device can be connected and disconnected while the computer is running.

To prevent data loss or other failures, we recommend the following procedure when disconnecting your USB3.0 storage device from your host computer system:

Before you shut down your PC remove the 8-BAY RAID STATION from your system's hardware configuration by double-clicking the symbol in the task bar. A menu will open up. Select the 8-BAY RAID STATION to securely remove it. Switch off the device and shut down your PC.

7.4 HDD HotPlug

The hard disk drives should not be hot-plugged, but can be unplugged while the system is running. However, to avoid data corruption or loss, make sure that the host system is not currently using any drive that is about to be unplugged.

8. Setting the RAID mode

To define a storage mode for the first time, make sure that the hard disk drives are mounted, then turn off the power before setting the RAID mode switches on the rear side of the 8-BAY RAID STATION to the desired mode.

To change the storage mode afterwards, set the RAID mode switches to the desired position. Press and hold the setup button, then switch on the device to create the new virtual volume(s).

Notes:

Creating new virtual volumes will destroy any existing data saved on the volumes!

Back up your data before reconfiguring the storage mode!

8.1 CLEAN mode

9. Rebuilding a redundant drive

The 8-BAY RAID STATION duplicates all data to separate drives in order to protect against data loss due to drive failure in R30 and R50 mode. The following example illustrates the procedure of rebuilding a redundant drive.

  1. If drive 2 fails, please remove it from the device (fig. 17).

  1. The 8-BAY RAID STATION will start rebuilding the virtual volume automatically (rebuild speed: approximately 200 GB/hour).

10. Troubleshooting

1. Device is not recognized

Make sure all cables have been properly connected.

For the USB3.0 controller the latest drivers and the newest firmware must be installed.

2. Cannot operate in O/S

Make sure the device is supported by your operating system.

3. Transfer speed is slow

If the device is connected via the USB2.0 interface, the speed will be around 30 MB/sec only.

4. When formatting under Windows XP/ Vista/ 7, the dialog box "Unfinished formatting" is displayed

Windows XP/ Vista/ 7 cannot format HDDs with capacities above 32 GB into FAT32, please choose NTFS as data format.

  1. When the system is damaged in LARGE mode, is it still possible to read the data?

No. The system is different from a RAID; the entire disk cannot be read.

11. Appendix

11.1. CLEAN mode

Function: In CLEAN mode each hard drive is displayed separately as one drive.

Notes:

When using a SATA host controller, CLEAN mode should only be used if the SATA host controller provides Port Multiplier (PM) support. If a host is not PM-aware, only a single drive is displayed (drive 1).

The CLEAN mode will not delete the drives partition if the drives were used as single drive before.

11.2 LARGE mode

Function:

The LARGE mode concatenates a series of physical hard drives into a single large volume, creating a seamless expansion of virtual volumes beyond the physical limitations of singularly connected hard drives.

    B --> H["Drive 6\n400GB"]
    B --> I["Drive 7\n750GB"]
    B --> J["Drive 8\n1500GB"]

Notes:

The hard drives 1 to 8 are concatenated into a single virtual volume in the Figure above with a storage capacity that is equal to the sum of each of the physical hard drives 1 to 8. 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.

11.3 R00 mode

Function:

In R00 mode the data is spread across all hard disks.

    D --> L["Drive 8 2000GB"]
    M["Volume 1280GB"] --> B
    N["Volume 1600GB"] --> D

Advantage/disadvantage:

R00 mode represents the best data speed but no data redundancy. R00 mode accelerates hard disk drive operating speed by using many disks simultaneously.

To implement the R00 mode, the 8-BAY RAID STATION Storage creates two single virtual volumes (SYS1 and SYS2) that are striped across all hard drives of SYS1 and SYS2, with a storage capacity that is four times of the smallest drive. SYS1 and SYS2 are then striped again across both virtual volumes. The storage capacity is twice the capacity of the smallest virtual volume.

The R00 mode can also be implemented using a single disk:

11.4 R30 mode

Function:

The R30 mode adds fault tolerance to drive striping by adding parity information to the data. R30 mode dedicates the equivalent of two drives (SYS1 and SYS2) for storing parity information and to stripe these again. The data and parity information is arranged on the drive array so that parity is written to two drives. The following example illustrates how the parity is rotated from drive to drive.

    RAID3 --> Parity9["Parity Generation"]
    RAID3 --> Parity10["Parity Generation"]
    RAID3 --> Parity11["Parity Generation"]
    RAID3 --> Parity12["Parity Generation"]

Advantage/disadvantage:

The R30 mode uses less capacity for protection and is the preferred method to reduce the cost per megabyte for larger installations.

In exchange for low overhead necessary to implement protection, the R30 mode degrades performance for all write operations. The parity calculations for R30 mode may result in write performance that is somewhat slower than the write performance to a single drive.

The resulting storage capacity of the virtual R30 volume will be "n minus 2"-times (n=number of disks) of the smallest drive.

    H --> V["Volume 1200GB"]
    I --> W["Volume 1200GB"]
    J --> X["Volume 1200GB"]

If one drive fails, the virtual R30 volume is still usable. When the offline drive comes back online, the appliance begins a rebuild process immediately to restore data redundancy. During this procedure the LED indications will notify you that a rebuild is in progress.

Notes:

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 virtual R3 volume during the rebuild, the rebuild process will take a longer time to complete, and the host data transfer performance will also be affected.

The R30 mode can also be implemented using a single disk:

11.5 R50 mode

Function:

The R50 mode adds fault tolerance to drive striping by including parity information with the data. R50 mode dedicates the equivalent of one drive for storing parity stripes. The data and parity information is arranged on the drive array so that parity is written to all drives (SYS1 and 2). The following example illustrates how the parity is rotated from drive to drive.

If one drive fails, the virtual R50 volume is still usable, but it is in a vulnerable state because its mirrored hard drive is inaccessible. When the offline drive comes back online, the appliance begins a rebuild process immediately to restore data redundancy. During this procedure the LED indications will notify you that a rebuild is in progress.

Notes:

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 virtual R5 volume during the rebuild, the rebuild process will take a longer time to complete, and the host data transfer performance will also be affected.

The R50 mode can also be implemented using a single disk:
