February 23, 20179 yr Hi, I just received my new rackmount chassis (https://www.xcase.co.uk/collections/4u-rackmount-cases/products/x-case-extra-value-rm-424-24-hotswap-bays), moved the hardware into the case and plugged my first 11 disks. I'm currently using three brand new "SFF8087 to 4x SATA" cables (https://www.amazon.fr/gp/product/B00S7KTWPE) to connect the first rows of disks to the motherboard and to some old SATA RAID controllers. The server turns on correctly, the 11 first disk tray LEDs are lit (blue), but not a single disk is detected by the motherboard. unRAID then loads successfully, obviously showing all disks as missing. Did I choose the wrong SAS to SATA breakout cables? What else should I check? I tried removing the old SATA controllers and only using the motherboard's SATA ports to begin with, but still no luck. The mobo is an Asus P8H77-V with an Intel Core i5. Thank you for your help Edit: I'm guessing its because of the cables, from what I gather the ones I bought are meant to connect 4 SATA drives to a controller, and not a SAS backplane to a controller like I'm doing right now...

February 23, 20179 yr Backplane to motherboard(vice versa ) sata are reverse breakout. HBA card to sata drives is forward breakout thats probably what you picked up. Check ur invoice to make sure might to return the cabke unless u plan on a hba card. Have fun

I'm a bit relieved 15 hours ago, Akio said: Have fun Thanks
