Hi All,
I have a chassis supporting upto 10 disks and an ASUS B150M Plus motherboard that has 6 native SATA ports. I have a large number (>10) WD Red 2TB disks lying around and was looking around for HBAs to expand my storage and found this certified refurbished one on Amazon at a very reasonable price in India. I have gone through @jgreco 's excellent post https://forums.freenas.org/index.ph...-sas-sy-a-primer-on-basic-sas-and-sata.26145/ but was unable to quite understand whether the part I have linked would work or not. Specifically, I am looking at answers to the following questions:
EDIT: The part number listed in Amazon is 25R8071-CR. I found a link to the specification of 25R8071 IBM SAS controllers here. It seems to be based on the LSI 1068E SAS processor. I can't figure out what the -CR stands for though.

Specifically, I am looking at answers to the following questions:
- Will this HBA work for me for the simple purpose of expanding my motherboard's capacity from 6 5400rpm SATA disks to 10?
- If so, what kind of cables would I need (sorry but I'm a complete noob to the whole SATA / SAS connectivity thing and the ports in the picture on Amazon kind of look like SATA ports to me)?
- Will I need to "cross-flash to IT mode" or some such and if so, how would I do it? Any links and pointers would be appreciated?
- Will it still work if I decide to replace my 2TB disks with higher capacity disks later on? I have read in some articles that certain older LSI HBAs have a 2TB cap?
