The recommendations typically go for PCIe x1-2port type cards
Well, an 8 port card (like HP H220 or similar) is a bit too
expensive if all you need is two more slots, and it's not
like mdadm is picky - anything goes, well, as long as it
meets minimum requirements (no I/O errors etc)...
If you're looking for something on an even larger scale,
maybe have a look at the Backblaze Storage Pod blog posts.
Although the hardware they use seems to be hard to get,
it might give you some ideas.
They actually use port multipliers, I actually wish they
were as widespread (and as cheap) as USB hubs, so we all
could simply put three or four disks to a single SATA port,
but alas...
Maybe next time.

Andreas,
The two links I gave are about $120 and $80. If I used 2-port ones,
it will be too many (to get 8 ports) and my experience with marvell
chipset cards (4-port) was not good. So, I thought LSI 8-port is better
and reasonably priced. I also saw several feenas threads talking about
these cards working well in linux. Do you see risk in buying these as
they may not be what they claim to be?
