If you stick with one of the "major players" (e.g. Dell, HP, IBM,
Adaptec, Emulex) and you're willing to pay a bit more, you'll probably
be just fine. Example:

http://accessories.dell.com/sna/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=342-0910

6Gbps dual-port SAS2 HBA, about $200 US, and I can pretty much guarantee 
it'll work with your kernel. Couple that to a JBOD and some drives and 
you're good to go.

If you stick with the cheaper stuff that's aimed at Winblows users,
you'll have a much harder time. While you may not think of it this way,
you're encroaching on "SOHO" (small home and office) territory, at least
as far as the manufacturers are concerned, and that's sorta where you
have to look.

I'd suggest spending your money on a decent HBA, and prowl eBay for
a JBOD (there's lots out there and on the used market, they're rather
cheap). The JBOD itself isn't a big deal--as long as it's compatible
with your HBA. The drives you use IN the JBOD are important.

Just my $0.02. It's your data, you know how secure you need it and what
you can spend.
