That is almost what I do, except that I only have one HBA.
We haven't seen many HBAs fail during the years, none actually, so we
thought it was overkill to double those too. But maybe we are wrong?


Question: if you use two HBAs on different PCI buses to
to MPxIO to the same JBODs, wouldn't this double your
peak performance between motherboard and disks (beside
adding resilience to failure of one of the paths)?

This might be less important with JBODs of HDDs, but
more important with external arrays of SSD disks...
or very many HDDs :)

Thanks in advance for clearing that up for me,
