Thinking about the controllers:
I am still looking for a viable replacement of LSI1068e-based cards for
home-built ZFS servers. This LSI chipset does not support drives larger
than 2TB which has become a serious limitation for me. I read that the
LSI2008 is supposed to be some kind of follow-up, and it should be
supported with recent FreeBSD's mps driver. However, I could not find any
cheap (non-hw-raid) cards with 8 channels (or more) like there are with the
old LSI1068 chipset. Are there any recommendations?
