    Note:

    You can create only one CacheCade – SSD Caching virtual drive because the full capacity of the virtual drive is used for the creation of a CacheCade – SSD Caching virtual drive.

  9. Enter a name for the CacheCade – SSD Caching virtual drive in the CacheCade – SSD Caching Virtual Drive Name field.

    The virtual drive name can have a maximum of 15 characters.

  10. Specify the write policy for the CacheCade – SSD Caching virtual drives.
    The write policy depends on the status of the energy pack. If the energy pack is not present, is low, is failed, or is being charged, the current write policy switches to write through.
    The options follow:
    • Write Through
    • Write Back
  11. Click Add CacheCade – SSD Caching Virtual Drives.
    The newly created CacheCade – SSD Caching virtual drives appears in the CacheCade – SSD Caching Configuration window just below the Add CacheCade – SSD Caching Virtual Drives section.

    If you want to modify the CacheCade – SSD Caching virtual drives settings before finishing the configuration, click the icon.

  12. Click Finish.
    A message appears stating that the configuration is complete.
