|BULK STORAGE TAPES & DISKS|
Understanding the topology and where Linux drivers fit in
There are two storage classes.
Streaming storage is tape. It cannot be manipulated in the same manner, it cannot be installed as a mountable device. It requires special tools for use, such as tar, mt, cpio, and archive utilities like Bru. Such devices are QIC 80 DAT, DLT tape drives, even when connected to the parallel port.
The following table illustrates the drivers (modprobe) for each block device, their heirarchy, and their relationship to each other
*ide is normally compiled in the kernel, not a module
*NCR83C8xx is an _example_ of a specific scsi card driver.
*ppp/imm refers to old / new drive types respectively
Note some interesting results from this table. ZIP / JAZ and LS120 are all handled by the same driver in their respective interfaces. If it looks like a duck, quacks like a duck, walks like a duck, it probably is, a duck.
ALL scsi (bulk storage) devices are handled by the scsi DISK module. If it looks like a duck, quacks like a duck, walks like a duck, it probably is, a duck.
