The output of ls -l /sys/block/*/device should give you an idea about how each device is connected to the system.

In the example below red is a virtual disk on an internal RAID controller, green is a CD-ROM connected via an IDE controller, and the rest are SAN-connected SCSI disks where "hostN" refers to the instance of the Host Bus Adapter they are connected to.

Code:
# ls -l /sys/block/*/device
