Is it a good or bad idea to split a raid group over two FC-AL
interfaces?
Somewhat bad... as has been talked about here before, there is a small write penalty introduced, on the order of 10%, which only introduces itself noticeably under heavy write loads. However, you should avoid it if you can.
Remember this is an F840. I beleive the issue was specific to the F700 series. The F840 does not have the same issue, plus it has 3 primary PCI buses to spread loads across.
