Can someone shed "simple" light on an extremely simple question.
How do you physicallly get 48 drives attached to an LSI that claims to
only have 2 internal and 2 external ports?
(the controller claims to support up to 240 drives).
I'm currently looking at getting a server with space for 8 x 512GB SSDs
running raid5 (or 6) and are looking for an well performing controller
with BBWC for the setup. So I was looking for something like the LSI888ELP.
