Would you give some more information if possible, on why the asr
controllers should be avoided and/or what issues they have?

I'm getting a little anxious, because I've been using tens of asr
RAID controllers at work for years and haven't realized (or simply
can't remember ;-) any issue except that the CLI management tool
isn't clear which option takes a physical or logical disk address.
