What do I need to connect my SCV2020 w/ 12G-SAS-4 Type B controllers to PE R630 Server?

Hello! I am relatively new to all of this, so forgive my ignorance. I work for a non-profit and I am trying to set up one of their unused R630s and an SCV2020 storage enclosure with dual e12G-SAS-4 Type B controllers as an off-site disaster recovery solution. The R630 does not have any external SAS HBAs installed in it, and I don't have any cables to connect the two if I did.

My question is which HBAs are compatible with my R630 and this storage unit (there seem to be so many part numbers out there and little documentation), and if I purchase said HBA, which cables would I need to connect the two?

Thank you!
