Jmbrown0311 :
I do have an adapter for the HDD which obviously connects to the sata port, so that I have all worked out.
Which adaptor are you using? I'm not aware of any active-mode SAS to SATA converters - only cables to allow SAS backplanes to be connected to SATA ports, allowing the use of SATA drives in them without having to buy a SAS host bus adaptor. (It used to be possible to get IDE to SCSI adaptors but I doubt there would be sufficient demand for it to be worth a manufacturer's while producing a SATA to SAS one these days.)
SAS drives use a different protocol (based on SCSI) compared with SATA drives, which use an evolved version of the old ATA ("IDE") protocol. While most SAS adaptors can automatically switch to speaking SATA when a SATA drive is connected, SATA adaptors can't speak SAS, nor can SAS drives speak SATA. (For this reason, by design, a SAS power/data cable will fit a SATA drive while the reverse is not true.)
If you want to use the drive, I'd suggest buying a cheap used PCIe SAS card (something like a Dell SAS 6) on eBay. You'll need a SAS fanout cable too unless you can find an adaptor with individual SAS (SFF-8482) connectors.
The Dell SAS 6 and many other LSI Logic adaptors use the SFF-8484 4-port SAS connector. The SFF-8087 connector is also quite common - Adaptec tend to use it on their cards. Make sure you get a Host Fanout cable, not a Target Fanout one - you want to fan out from an SFF-8484 connector on the host (SAS card) to individual SFF-8482 connectors for the target (the drive). The Target Fanout goes in reverse - it's for connecting a backplane with a multi-lane connector to separate connectors on an adaptor. Read the description super-carefully and ask for clarification if it's not absolutely explicit about the type - I've got several Target Fanout cables sitting around which were incorrectly-described and would have cost more to post back to China than I would have got as a refund. There's a list of the far-too-many different SAS connector types on Wikipedia
