Customers who implement particular Bare Metal server types are able to customize the configuration using both JBOD (HBA) and RAID modes. For additional information on which servers support this feature refer to our Bare Metal FAQ. Using this guide customers will leverage the Dell OpenManage Server Administrator (OMSA) to create and delete RAID volumes to meet specific performance and availability needs.


  • Purchase a Bare Metal Server that support JBOD/RAID:
    • 20 cores E5/256 GB RAM/2x800GB SSD/12x2TB 7200 SATA
    • 16 cores E5/256 GB RAM/2x800GB SSD/4x4TB 7200 SATA

  3. Change controller mode to desired mode and hit Apply changes and Reboot the server immediately. You can see the current controller mode on this page.

  • Changing the controller mode requires a reboot.
  • If you are changing from RAID to HBA mode, you will need to delete any security keys, and existing RAID volumes before it will let you switch to HBA mode. Don’t forget to convert your disks back to Non-RAID disks.

Creating a RAID volume

  1. Connect to OMSA

  2. Before we can create a RAID we must convert the disks to RAID mode. Select Storage, then under available tasks for the controller choose Convert to RAID Capable Disks.

  3. Select the disks you wish to convert to RAID capable and apply.

  4. Now choose “Create Virtual Disk” from the Available task list.

  5. Choose Express Wizard or Advanced Wizard and your desired RAID level from the drop down list and hit continue. Advanced Wizard is recommended for most cases as it permits the user to define the number of disks in the RAID Virtual Disk instead of using predefined configurations.

  6. Type in a name for your volume. Validate that all of the settings you expect are correct. Note that you may set up a hot spare at this time if you choose and your RAID setting allows it.

  7. Once completed, you should have a new RAID volume available. You will need to format it, and assign it a drive letter or mount point within the Operating System before you can use it.

Deleting a RAID Volume

  1. Connect to OMSA

  2. Navigate to Storage, PERC H730 Adapter, Virtual Disks.

  3. Choose Delete from the available tasks on the Virtual Disk you wish to delete.

  4. OMSA will warn you that all data will be lost. Confirm this dialog box and your volume will be deleted.
