Wasn't really sure where to post this, but we'll try here. I recently rotated my i7 920 build out of "main PC" use, so I was going to reuse it as a storage / VM box to play around on. Using the Asus P6T Deluxe original version with the SAS controller. I did a full CMOS reset and started from scratch with a bunch of 2 TB drives I had around. But I'm running into some weird issues with the storage setup on this motherboard. If I have the Marvell controller(s) enabled for the SAS ports to work, I am able to get into the controller and create a RAID there between two drives. However, none of the other drives plugged into SATA ports seem to show up. This is with the storage configuration set to AHCI. If I set it to RAID, I am prompted with an Intel RAID menu where I can attempt to create a RAID between the other 6 SATA ports (SAS ports apparently disabled by doing this). This would be (almost) fine, except with 5x2 TB drives trying to create a RAID 5, it puts the total storage as being something like 800 GB (???). Should be around 8 TB I believe. So, I'm not really sure how to configure this, or if what I want is even possible. I'd like to have the SAS controller be a RAID1 with two drives (as a boot/OS logical drive) and then have the rest of the SATA ports be a RAID 5 with the remaining drives. But I can't seem to figure out how to get that to work. I know it's an old motherboard, but does anyone have any experience with this? I've tried searching elsewhere but there's not a lot of data on the whole storage subsystem on this board.
