Think of the middle two digits as (number of external ports, number of internal ports). For example, I have a 3442E-R which has 4 internal and 4 external ports, the 3800 has 8 external ports and 0 internal, and so forth. One place this breaks down is with cards like the 8888; it has a total of 8 ports, any group of 4 of which can be mapped to internal or external ports.

I think the iButton is just used as an unlock code for the builtin RAID 5 functionality. Nothing the end user cares about, unless they want RAID and have to spend the extra money. > * SR = Software RAID IT = Integrate. Target mode. IR mode is not > supported. Integrated target mode lets you export some storage attached to the host system (through another adapter, presumably) as a storage device. IR mode is almost certainly Internal RAID, which that card doesn't have support for. > also there seem to be two different kinds of quad-SATA connector on > these SAS cards so there are two different kinds of octopus cable.

I'm not sure what you mean by this. SAS controllers can control SATA disks, and interact with them. They don't just "show up"; they're first-class citizens.
