Okay so this is something I've been a bit confused about, and probably is an easy thing to clarify.
Take the LSI MegaRAID 9260-4i card like this one:
This card has a single SFF connector and is intended to connect to up to 4x disks.
However on LSI's website, under specifications:
It says that it supports "Up to 128 SATA and/or SAS devices", and "64 logical drive support".
How is this possible? Are you supposed to just put multiple cards into a server? If so, do the cards automatically detect each other and handle it or is there special configuration needed?
Can you mix and match LSI cards of the same product line? E.g. can I put in 2x LSI MegaRAID 9260-4i cards and 1x LSI MegaRAID 9260-8i card, for a total of 16 disks?
