Sata controller on a SAS-backplane.

[-Mr Mullet-]

Hi.

Probably been asked about before, but could not find anything doing a search.

Is it possible to use a standard SATA controller on a SAS backplane with SATA drives in it?

I'm building a Norco RPC-4224 server with a Tyan S5512WGM2NR motherboard with onboard LSI 2008 SAS controller and 4xSATA-II and 2xSATA-III ports.

I will start my build with 12 Hitachi 5K3000 2TB drives (will add more later when they fill up and drives get even cheaper...) and was planning to connect the LSI2008 to 8 of the drives and the last four to the SATA-II controller using a SFF-8087 reverse breakout cable.

2(8)xSAS LSI2008 -> SAS-backplane -> 8xHitachi 5K3000 2TB
4xSATA-II -> SAS-backplane -> 4xHitachi 5K3000 2TB.

So will this work, or do I have to buy a "SAS" controller to get my last 4 drives working?

I will of course add more SAS controllers (or expander) later when installing the last 12 drives.

Regards.

Since that backplane has no logic, it is no different than a cable.

that breakout cable is all you need
