Asempris,  The C2100 does support SAS SSD's at 6Gbps, but won't support the use of SATA SSD's. With the back plane there are 3 configurations. They are; 12 x 3.5” 1 to 1 backplane 12 x 3.5” expander backplane 24 x 2.5” expander backplane  They can support the following drive configurations. 12 x 3.5” SAS or SATA drives OR Up to 24 x 2.5” SAS, SATA, or SSD drives Plus you can also use up to 2 x 2.5” SATA or SSD in internal bays as well.   Let me know if this helps answer your questions.   
Hi, Is the c2100 backplane passive? would it support ssd drives at 6gb/s on an LSI 9260-8i? I'm looking to install 6x ssd drives in a raid 10 configuration and would like to confirm that they would run a 6gb/s. Thanks,
c2100 backplane speed 6gb/s with ssd drives?
