Tri-Mode controllers make this SATA/SAS/NVME interface mess simple by using a single controller, expander, and disk backplane.
Tri-mode controllers alone are not enough, here the disc backplanes also come into play.
For the perfect Tri-Mode operation, system needs to have
• One Backplane
• One connector
• Less high-speed lanes to backplane
• One Mid-plane
• Tri-mode Expander
• One HBA / RAID Controller
Tri-Mode controllers should be PCIe 4.0 and it means that the slot and our disks in the server should be 24G.
On a PCIe 3.0 server, you can use all disk types at the same time with tri-mode controls and U.2 and/or U.3 disk backplane, of course, it will work at PCIe 3.0 and U.2 speed in terms of performance
