SATA – RAID card with 1x Mini-SAS connector: How to physically connect 16 disks?

I am looking for a MegaRAID SAS 9240-4i Sgl card with a single X4 Mini-SAS SFF8087 connector. As far as I know, such a connector can be expanded to 4 SATA disks. So , I know how to connect 4 SATA disks. However, the document says that it supports up to 16 disks in a RAID volume. My question is; how to physically connect these 16 disks to a card with only one connector?

This is where the backplane comes in (I tried to find relevant information, but couldn’t figure out how they work with the RAID controller).?

Yes, this is where SAS expanders, chassis backplanes and branch cables come in. You can get a breakout cable that provides 4 ports from the SFF-8087 mini-SAS connector. You can also try something similar to HP SAS Expander, which provides more SFF-8087 ports from a single RAID controller for your use The detailed forum about HP extenders is available here.

I mentioned the backplane only because some embedded extenders allow them to accommodate more than 4 or 8 drives. You may not be using A system with a SAS backplane, so please ignore this part and focus on the expansion of the RAID card level.
