Unsaved Data in the Controller Cache
The dirty cache LED (marked with the icon) informs you that there is data in
the cache that has not been saved to non-volatile memory. Such data is
sometimes called “dirty,” not to suggest it is corrupted in some way but because it
has not been saved to a physical drive.

Caution
If there is unsaved data in the controller’s cache, the dirty cache
LED shines amber. During this time, do NOT power down the
VTrak. Wait until the LED goes dark.
