The clue is in the name, its an LSI card, not an adaptec one.
And it is supported by the megaraid2 driver.

Again, its not adaptec, but yes it can do it. There is barely a
controller that
cannot these days, a real array controller I'm talking about :-0
You need to choose your filesystem well, do you need online expansion of not?
