I’m toying with the idea of grabbing a 12G trimode 8i card and possibly expanding out the future. Lets say a 9400-8i. Drives will be split between enterprise and consumer SSD’s.

Aside from bandwidth on older expanders being 6G and possibly implying pre-trimode era hardware (for arguments sake a LENOVO 03X3834 https://www.newegg.com/p/14G-000U-000K2 ), are there any gotcha’s with using older expanders with newer HBA’s like SCSI unmap and whatever else is a “trimode” feature?

my guess is there’s a controller under the expanders heatsink which would not pass through the newer instructions.
