Dell storage 1200 which card to choose for 730dx server?

Question

Dell

The essence of my question is:
a friend has a DELL PE R730xd server with 80 TB, about 100 cameras are written to it, now the task is to extend the recording archive as much as possible, I calculated that you need to have a total of 280 TB for the archive. I read
the good DELL website and figured out the following solution, that you need to buy two PV MD1200 with 10 TB screws, stack them via SAS. Question for knowledgeable people:
-what kind of HBA card do I need to buy to the 730xd server in order to pick up these shelves?
-who has MD1200 , how is it configured by the same MD_StoargeArray_Mananger ??
- Is it possible to use hard not DELL, but for example Seagate?
