2.3 Assembly Steps

This section describes the process of installing drives into the OWC ThunderBay Flex 8 if purchased as a bare enclosure.

1. Insert one of the included keys into the lock on the upper right of the faceplate.

2. Turn the key clockwise, then pull it towards you. The faceplate will swing open.

3. Once the faceplate has swung open as far as it will go, lift to remove it.

4. For each tray you wish to remove, turn the thumbscrew counter-clockwise until you no longer feel resistance. Then hold onto the thumbscrew and pull the drive tray out.

5. Set the drive tray on your work surface as shown. If you are replacing an existing hard drive, unscrew it from the drive tray at this time. Note: the highlighted screw holes are for 2.5-inch drives (SATA or U.2). The holes for 3.5-inch drives are highlighted in green (Step 7).

6. Place the hard drive inside the drive tray as shown. The label should face up and the SATA connectors should be on the far rear corner of the drive.

7. Fasten the drive into the drive tray using six of the included screws (three per side). 2.5-inch drives require four of the fine-thread screws.

8. Slide the drive tray back into the rails in the ThunderBay Flex 8 and push until it is seated fully, then push in on the thumbscrew and turn it clockwise until it stops turning. If you encounter resistance, do not force the drive tray. Remove it, check to make sure there are no obstructions and that the drive tray is lined up correctly, then try again.

9. Plug the power cable into the OWC ThunderBay Flex 8 power port located on the back and into a power outlet. The Power LED will illuminate a solid white.

10. Connect the included Thunderbolt cable into one of the two Thunderbolt 3 ports located on the back of the OWC ThunderBay Flex 8 and into a system. The Power LED will illuminate a solid blue.

11. The installed drives are ready to be formatted. Move onto Section 2.5 “RAID Configuration Options” for instructions on how to format and configure the OWC ThunderBay Flex 8.

2.4 PCIe Card Assembly Steps (Optional)

This is an optional section that describes the process of install a PCIe card in the OWC ThunderBay Flex 8.

1. As you face the front of the device, the side-panel on the left needs to be removed. Use the included hex key to loosen and remove the four fasteners holding the panel in place.

2. Remove the side cover and set it aside.

3. Remove the PCIe slot cover then set the screw aside. Store the slot cover; it will not be needed to complete this installation.

4. Align your PCIe card’s connector with the open slot then install the card as you normally would when installing into a desktop computer.

5. Use the screw from Step 3 to affix the card’s bracket to the case.

6. If your PCIe card has I/O Ports, double-check the back of the device to ensure the bracket is level / that none of the ports are obscured by the plating on the back of the case. If needed, loosen the screw you set in Step 5, re-align bracket as needed, and re-tighten the screw.

7. Set the side cover back on the case, making sure the holes are aligned with the four fastener holes, then re-affix the four fasteners removed in Step 1.

2.5 RAID Configuration Options

OWC SoftRAID RAID Configuration

Downloading and installing the latest version of OWC SoftRAID is recommended to experience the best performance from the OWC ThunderBay Flex 8.
- NOTE: OWC ThunderBay Flex 8 devices come bundled with "3 Years of SoftRAID Premium Access". Please visit OWC SoftRAID Product Details for more information regarding SoftRAID and the bundled Premium Access.
SoftRAID will assist with formatting the installed drives and setting up a RAID volume.
- NOTE: The OWC SoftRAID license is located on the inside of the Security Faceplate.

Mac OWC SoftRAID Setup

Download OWC SoftRAID for Mac.
- Please review and follow the steps outlined in OWC SoftRAID Installation for Mac.
Please review and follow the instructions outlined in Creating a macOS OWC SoftRAID Volume.

Mac RAID Configurator

Open the “Disk Utility” application on your Mac.
Choose “File” and select “RAID Assistant”.
Select a set type:
- Striped (RAID 0) set: A striped RAID set can speed up access to your data. You can’t create a RAID set on your startup disk; you must first start up your computer from another disk.
- Mirrored (RAID 1) set: Protect your data against hardware failure with a mirrored RAID set. When you create a mirrored RAID set, your data is written to multiple disks so the information is stored redundantly. You can’t create a RAID set on your startup disk; you must first start up your computer from another disk.
- Concatenated (JBOD) set: Increase storage space with a concatenated disk set. If you need one large disk, but you have several smaller disks, you can create a concatenated disk set to use as one large disk.
Select the checkboxes of the disks you want to include in the set.
For each disk, click the pop-up menu in the Role column and choose “RAID slice” or “Spare” to designate the disk as a standard member or spare in the set, then click Next.
Enter a name for the RAID set in the RAID Name field.
Click the Format pop-up menu, then choose a volume format that you want for all the disks in the set. (See File system formats available in Disk Utility.)
Click the “Chunk size” pop-up menu, then choose a disk chunk size that you want used for all the disks.
1. When you create a striped set, chunks of data from the same file are distributed across the drives. Ideally, you want data distributed across drives evenly and at an optimum size so that it can be efficiently accessed. If you want high data throughput from your set, choose a smaller chunk size so that data is spread across the drives and one drive can be accessing data while another is seeking the next chunk. With mirrored disk sets, choose a chunk size that matches the data you’re accessing. For example, when working with video files, your Mac is accessing large chunks of data, whereas when using a database of many small records, your disks may be accessing smaller chunks of information.
If you are creating a mirrored RAID set, select the “Automatically rebuild” checkbox to allow the set to be automatically rebuilt when member disks are reconnected
Click "Create" and then click "Done".

Device Management

3.1 Drive Failure

If the OWC ThunderBay Flex 8 was configured as a RAID 0, the data on the array is lost and the disk is no longer usable.
If the OWC ThunderBay Flex 8 was configured as a RAID 5, the RAID card will alert the user with a beeping tone. The RAID can continue to be used, but the drive should be replaced immediately.

3.2 Replacing Drives

The Hot-Swap function can be used to rebuild disk drives in arrays with data redundancy such as RAID level 1, 3, 5, 6, 10, 30, 50 and 60. The data will remain accessible via the functioning drive until the array is rebuilt with a new drive.
- If the enclosure was purchased with drives and it is still under warranty, contact OWC technical support for assistance (see Section 4.4 “Contacting Support”). If the unit is outside its warranty or was purchased without drives, follow the assembly instructions to access and replace the failed drive.
  - NOTE: A failed drive must be replaced with an identical drive (model, capacity, firmware). Refer above to section 2.3 “Assembly Steps” for drive replacement steps.
  - NOTE: The OWC ThunderBay Flex 8 needs an active data signal to remain powered on. If it is disconnected from the computer, or if the computer goes to sleep or turns off, the device will power off. To minimize the rebuild time, it is recommended to keep the device connected to the computer (with the computer powered on), and disable any drive sleep settings on the computer for the duration of the rebuild.

3.3 Manually Unmounting Volumes

To ensure no data is lost during normal use, always eject or unmount the corresponding volume(s) from the operating system before powering off and disconnecting the device. Unmounting options are provided below.
