Welcome to the Community,
the B110i is a software RAID controller, i.e. one that requires additional software within the operating system.
ESXi only supports hardware RAID controllers like a Smart Array P410 Controller (in case of the ML110 G7) which transparently present RAID LUNs to the operating system. If you are going to get such a controller, make sure you get one with BBWC/FBWC. This makes a huge difference in performance.
