Hi, I've been researching for a while now and am looking for clarity as I can't seem to find the all of the answers I'm looking for.
My setup is a conventional home server (old Z68 w i5-3550) but I'm maxed out at 6 SATA devices, idea is to add an HBA to connect > 6 devices. RAID is not in scope. Questions (and please correct if and where wrong):
- An HBA can add both SATA or SAS HDDs, depending on the cable used.
- If two cables (arrays/ports) are used, I could load one up with SAS HDDs and the other with SATA HDDs
- Connecting the boot HDD to the motherboard SATA port reduces conflicts with the HBA (i.e. the HBA is only for additional non-boot required devices (DVDR, SAS HDDs, SATA HDDs, etc.) in this case)
- The SATA HDDs would continue to require power from the PSU
- The SAS HDDs would not require power from the PSU and would be powered by the HBA?
- A backplane is not required with the use of an HBA
- When is an backplane required?
