Upgrade from RAID 0 to RAID 10

The ExtraHop system is configured by default with RAID 0 and four installed four drives. On the EH8000, EDA 6100, EDA 6200 you can purchase additional drives from ExtraHop and upgrade to a RAID 10 configuration. This guide explains how to upgrade the EH8000, EDA 6100, and EDA 6200 for RAID 10 functionality.

You must have write access to the Admin UI on the ExtraHop appliance and the ExtraHop rescue media.

Enable RAID10 configuration

  1. Insert the ExtraHop Rescue Media into the appliance

  3. Restart the Discover appliance so that it boots from the rescue media.
  4. Choose from the following options:
    • If your Discover appliance is configured with the default settings, proceed to step 5.
