SAS JBOD external enclosure

[ochadd]

I have a white box backup replica target that is out of internal storage and SATA ports. A direct attach tower form factor external SAS enclosure with 3.5" drives would seem to be the best choice. Can anyone recommend a fairly inexpensive 8 disk box and controller?

I'm familiar with Dell MD DAS boxes and PERC 800/810 controllers but the footprint just doesn't work.
