How to know if I have a SATA compatible machine without opening the box

How do I know if I have a SATA compatible machine without opening the box? Or is the only way to open up the box and look at the connectors?

Check what PCI adapters are installed. The way how to do it depends on your operating system, e.g. Device Manager in windows or lspci output in linux. If your computer is a PC, you should check the BIOS messages during the boot process.

If your SATA controller supports hot swap, it should "just work(tm)."

To force a rescan on a SCSI BUS (each SATA port shows as a SCSI BUS) and find new drives, you will use:

echo "0 0 0" >/sys/class/scsi_host/host<n>/scan

On the above, < n > is the BUS number.

Does anyone know if “SATA II” drives are compatible with a Dell SAS 5i/R

Speed negotiation is part of the SATA initialization protocol. Any controller worth it's weight properly implements this. Some early VIA and SiS chipsets were known to fail at this, but I would expect better from the SAS 5i/R (LSI, I believe?)
