Is this a small machine, such as a typical PC with a single motherboard? If so,
then don't worry about having multiple controllers for at least two reasons:
1. some BIOS won't allow boot access to more than one controller
2. the affect on availability is very small because the reliability of
modern controllers is very high, especially SAS/SATA controllers
Do worry about the disks themselves, as they should be the least reliable
component.
