this is my biggest gripe with roll your own 'whitebox' storage systems 
today...   you get a brand name server, like HP or Dell, with HP or Dell 
storage, and when a drive fails, the failure light on that drive comes 
on bright RED, so there's no QUESTION what drive is offline and needs 
replacing....    whitebox raid or HBA card, with generic SAS expander 
trays, or whatever?  good luck, implementing that failure mechanism is 
left as an exercise to the reader, without any  clue how to go about it.
