Please let me know if my question does not makes any sense as I am not sure if I am interpreting it correctly from my thoughts due to my lack of technical knowledge on this.
If I am using a motherboard which has a connection for a SFF-8087 to 4x cable such as this SFF-8087 to 4x SATA connection.
I am still learning about SAS but was told to build a system from a potential employer utilizing these connections. However, I am just not sure I understand the concept on how the system will treat the SATA connections which are going into the SAS port via this cable.
Also what would be the advantage of doing it this way as opposed to just connecting the SATA drives directly into the SATA motherboard ports? I believe the built-in SAS connection may be an integrated RAID controller.
Although, yes I can just go ahead and connect all the cables that fit I would like to have a better grasp of what I am doing such as:
- If a motherboard has SAS connections, should I automatically assume it has some type of RAID controller built-in or is this on a case by case basis?
- Do All RAID controllers have only SAS connections?
- Even though the SATA drives are connected via a SAS connection, are they still just treated as SATA drives or as SAS technology?
