This chapter describes direct-attached storage—that is, storage devices directly connected to a Windows NT server. Chapter 1 described the Windows NT storage I/O stack in detail. This chapter explains developments in the Windows NT storage I/O stack designed to improve the handling of newer Fibre Channel and SCSI devices that appear to the Windows NT server as direct-attached devices.
