Supermicro H11DSi Motherboard + BPN-SAS3-826EL1-N4

[AlexeyAA]

Sorry, I'm a complete newbie.
So I've got SuperChassis 826BE1C4-R1K23LPB with H11DSi Motherboard and as far as i'm concerned the backplane model is BPN-SAS3-826EL1-N4 with some SATA disks in it.
Unfortunately, there wasn't any cables for moterboard-backplane connection included, so I decided to think logicaly - I have two MiniSAS SFF-8087 ports on motherboard and a lot of MiniSAS HD SFF-8643 on backplane. CBL-SAST-0507-02 seemd to be the right choise for me, so I've bought one, but it didn't work - there wasn't any sign of my SATA disks in BIOS.
Would you kindly explain, what I'm doing wrong?..

The onboard controller is SATA only, so it can't be connected to a SAS expander, you need a HBA with SAS support, like an LSI 9211-8i, 9300-8i, etc.
