Thanks. I took a look at Areca. The fan on the controller board is a big
warning signal for me (those fans are in my experience the single most
unreliable component ever used in computers).

Can you say a bit more about the likely problems with the CLI ?
I'm thinking that I configure the card once, and copy the config
to all the other boxes, so even if it's as obscure as Cisco IOS,
how bad can it be ? Is the concern more with things like a rebuild;
monitoring for drive failures -- that kind of constant management
task ?

How about Adaptec on Linux ? The supercapacitor and NAND
flash idea looks like a good one, provided the firmware doesn't
have bugs (true with any write back controller though).
