I have a DELL 2950 with a PERC5/i controller and a SAS backplane and my intention is to switch to SATA on the cheap. I don't even have drive trays.
This backplane has SAS ports. I just bought 2 trays. Unfortunately those trays do not include interposer boards (SAS/SATA adapter) and I can't afford to buy these.
I see there is an additional SAS port on the PERC and I've read that there is an 1SAS-to-4SATA cable (http://www.otto.de/DELOCK-KabelAdapter-SAS-32pin-zu-4x-SATA-Metall-SFF-8484-4x-SATA/shop-de_dpip_A91355P-0/#Ueberblick).
Can I use that instead of the interposer method? I probably just have to connect it from the PERC to the hard drives...
Where can I get the power cables for the drives?
