General Description
The NCR SCSI Device Management System (SDMS) is a com-
plete software package that solves the increasingly complex
problem of managing system I/O. It seamlessly addresses hard-
ware and software interfaces by supporting the NCR family of
SCSI processors and controllers, and a wide range of SCSI
peripheral devices, while offering interoperability across applica-
tion programs, operating systems, and host platforms. SDMS
consists of a resident SCSI BIOS that manages all SCSI controller
or processor specific functions, and a series of SCSI device drivers
that provide operating system and peripheral specific support.
SDMS provides a standard method to interface SCSI I/O sub-
systems with devices, operating systems, and application software.
It also enhances system capabilities already provided by SCSI
controllers and processors by facilitating multi-threaded I/O
support, system-wide SCSI device access, and creation of new
applications.
