I am building out a new server and I am using a Supermicro SC745 TQ-R920B chassis. My mobo and raid controllers are both SAS2/SATA iii. The backplane on the chassis is a SAS743TQ, which is listed as a SAS and not a SAS 2 backplane. Now it seems to me the besides basic diagnostics a backplane is just a physical connection and so it would not matter. So my question is, will that backplane work with SATA iii/SAS2? Thanks!
