How to use SAS HDD's on Lenovo ThinkStation S30?

I am currently using 3 SATA HDD’s on my Lenovo ThinkStation S30. I now wish to switch to SAS HDD’s. I see that the motherboard is equipted with 3 blue coloured SATA ports for the use of SAS drives.I have 2 questions:

1. How can I get SAS drives to work when PSU and board has SATA connectors independently, whereas I need a one cable connector to plugin the HDD’s.

2. I read in the community section elsewhere that the board needs to be enabled for SAS drives to work. I couldnt understand the picture on the web page and neither was anything mentioned regarding enabling it. Looking at the picture it seemed as if I need a (hardware) electric board which needs to be pluged in or something.

Please advise. I will be grateful.

Thank you.

P1 2nd Gen – Other TrackPoint and Touchpad-Button Options?



I’m quite happy with my new P1 2nd Gen, except the pointing devices suck. Lenovo seems to have switched the TrackPoint to ALPS which comes very stiff, choppy and inaccurate. I played around with udev rules and acceleration settings which made it a bit better, but it is still far from the awesome accuracy and smoothness of the W540, my last machine. Same with the three buttons on top of the TrackPad – especially the left one doesn’t react reliably when hit on the lower right corner. I have to press a second time every ten clicks or so. This definitely sucks, so my question is: Is anyone aware of other manufacturers/options of especially TrackPoints and TouchPad-buttons for the P1 apart from ALPS?
