It would be helpful to check the PCI IDs of that card using "lspci -n" 
or "lspci -nn". I just saw the current EL7 kernel provides

# ls -Al 
/lib/modules/3.10.0-957.27.2.el7.x86_64/kernel/drivers/scsi/aacraid/
total 56
-rw-r--r--. 1 root root 56884 Jul 29 20:07 aacraid.ko.xz

and "modinfo aacraid" shows a long list of supported devices.

According to 
https://adaptec.com/de-de/speed/raid/aac/linux/aacraid_linux_rpms_v1_1_7-29100_tgz.php 
the module should be a fit for the Adapted RAID 51645.
