The first entry listed (sda) is the device, the subsequent entries
(sda1-15) are the partitions on the device.

The 8 is a major number and the numbers afterwards are called minor

SCSI), the minor number represents the instance (you can have many

You can tell that by the numbers on the end of the device (sda1 is the
first partition, sda2 is the second and so on).
