A Remote Disk Driver
Douglas Comer · 2011
Earlier chapters explain I/O devices and the structure of a device driver. Chapter 16 describes how block-oriented devices use DMA, and shows an example Ethernet driver. This chapter considers the design of a device driver for secondary storage devices known as disks or hard drives. The chapter focuses on basic data transfer operations. The next chapter describes how higher levels of the system use disk hardware to provide files and directories.
