4. Setup Guide

4.1 Installing Hard Drives

1. Ensure the enclosure is powered off and disconnected from your computer.
2. Gently slide open the enclosure cover or access the drive bays.
3. Insert your 3.5-inch SATA hard drives into the designated bays. Ensure they are securely seated.
4. Close the enclosure cover.

Note the internal structure designed to hold the drives securely. For more information on compatible drives, you may visit Western Digital Red drives.

4.2 Configuring RAID Modes

The Yottamaster DR2RU3 supports RAID 0, RAID 1, and SPAN modes. The RAID mode is set using switches located at the rear of the enclosure.

1. Locate the RAID mode switches on the rear panel of the enclosure.
2. Refer to the diagram below and set the switches according to your desired RAID configuration.
3. After setting the switches, press the RESET button (usually a small pinhole button) to apply the new RAID configuration. This action will erase all data on the drives, so ensure you have backed up any important information before proceeding.

Important: Changing RAID modes will erase all data on the hard drives. Always back up your data before reconfiguring RAID settings.

4.3 Connecting to Computer

1. Connect the 12V/4A power adapter to the enclosure's power input and then to a power outlet.
2. Connect the USB 3.0 data cable from the enclosure's USB 3.0 Type-B port to an available USB 3.0 (or higher) port on your computer.
3. Power on the enclosure. Your operating system should detect the new storage device.
4. For new hard drives, you may need to initialize and format them through your operating system's Disk Management (Windows) or Disk Utility (macOS) before use.

5. Operation

5.1 Understanding RAID Modes

The Yottamaster enclosure offers flexible RAID configurations to suit various needs:

• RAID 0 (Striping): Combines the capacity of both drives into a single volume, distributing data across them. This mode offers the highest read/write speeds but provides no data redundancy. If one drive fails, all data is lost.
• RAID 1 (Mirroring): Creates an exact copy of data on both drives. This provides excellent data redundancy; if one drive fails, your data is still safe on the other. The usable capacity is limited to that of a single drive.
• SPAN (Concatenation/JBOD): Joins the drives sequentially to form one large volume. Data is written to the first drive until it's full, then to the second. This mode maximizes capacity but offers no performance benefits or data redundancy.
• PM (Port Multiplier/Individual): Each drive is recognized as a separate, independent volume by the operating system.

5.2 Auto-Sleep Function

The enclosure is equipped with an intelligent auto-sleep function to conserve energy and prolong the lifespan of your hard drives. If there is no data exchange or activity for 10 minutes, the hard drives will automatically enter sleep mode. The drives will wake up automatically when data access is initiated.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the enclosure. Do not use liquid cleaners or aerosols.
• Ventilation: Ensure the cooling vents on the front and rear of the enclosure are not obstructed to maintain optimal heat dissipation.
• Safe Removal: Always safely eject or unmount the storage device from your operating system before disconnecting the USB cable or powering off the enclosure to prevent data corruption.
• Firmware Updates: Periodically check the Yottamaster official website for any available firmware updates for your model to ensure optimal performance and compatibility.
