It should, but the 24 bay backplane for the front is really expensive. Almost better off buying a new chassis given the cost of a used 847.Fairly certain that it also works in the 12 bay portion of the 847.
My plan is fast SAS3 on the 12 bay and SAS2 spinners in the 24.

The seller digitalmind2000 on eBay has been auctioning some 847s off one at a time and they’ve been going for less than $200. I even got mine for significantly less than that.It should, but the 24 bay backplane for the front is really expensive. Almost better off buying a new chassis given the cost of a used 847.
