Creating RAID 10

Creating RAID 10

Scenarios

The PM8068 supports SAS/SATA HDDs and SSDs. Hard drives in one RAID array must be of the same type, but can have different capacities or be provided by different vendors.

Workflow

Procedure

Back up data on hard drives and access the Configuration Utility main screen. For details, see Logging In to the Configuration Utility.

Select a member hard drive.

  1. On the screen shown in Figure 11-3, select Logical Device Configuration and press Enter.

    The Logical Device Configuration screen is displayed, as shown in Figure 11-21.

  2. Select Create Array and press Enter.

    The hard drive list is displayed, as shown in Figure 11-22.

    Figure 11-22 Hard drive list

  3. In the Select drives to create Array area, press the space or Insert key to select hard drives to be added to the array.

    The selected hard drives are displayed in the Selected Drives area, as shown in Figure 11-23.

    Configure array properties.

  4. Press Enter.

    The Array Configuration screen is displayed, as shown in Figure 11-24. Table 11-8 describes the parameters displayed on the screen.

    Parameter

    Description

    Array Type

    Specifies the RAID level of the array.

    Array Label

    Specifies the array name defined by users.

    Array Size

    Specifies the array capacity.

    NOTE:

    This parameter is set to the maximum value by default. If multiple logical drives are to be created, manually set the array size.

    Stripe Size

    Specifies the stripe size (8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256 KB, 512 KB, and 1024 KB for option).

    Create RAID via

    Specifies the operation to be performed after an array is created.

    • Default: No operation is performed after an array is created.
    • RPI: Perform initialization after an array is created.
  5. Select RAID 10.
  6. Configure the other RAID parameters. For details, see Table 11-8.
  7. Select Done and press Enter.

    The system creates an array and performs the operations defined in Create RAID via.

    After the array is created, the system displays the maximum capacity of the array.

  8. Press any key to return to the Figure 11-21 screen.

    (Optional) Create multiple logical drives.

    • This operation can be performed only when the array size is smaller than the maximum value.
    • A maximum of 64 logical drives can be created for each array.
  9. After the array is created, select Manage Arrays and press Enter, as shown in Figure 11-21.

    The array list is displayed.

  10. Select the array for which multiple logical drives are to be created, and press Ctrl+C.

    The array configuration screen is displayed.

  11. Repeat 6 to 8.

    You can create multiple logical drives based on the actual situation. For example, after two logical drives are created, select Manage Arrays and press Enter, as shown in Figure 11-21. On the displayed screen, select the array for which multiple logical drives have been created, and press Enter. The configuration results are displayed, as shown in Figure 11-25.

    Figure 11-25 Configuration results

    Check the configuration result.

  12. On the screen shown in Figure 11-21, select Manage Arrays and press Enter.

    The array list is displayed.

  13. Select the target array and check the configuration results.
