I use newisys nds-2240 chassis. They were designed to be replacements for
the 620j, which left a vaccum in the market when LSI sold off its chassis
division to netapp. 

The devices work flawlessly. I use them in an all sas environment. I put the
sata based l2arc disks on a separate controller, on a passive midplane, in
the server chassis.

If you buy the disks from newisys/sanima-sc, they'll even burn the drives in
so you can avoid infant mortality. 

It has been a very smooth ride.
