REFERENCE MANUAL
General Description, Functional Description, and Operating Instructions for the
DSS190 and DSS190B Disk Storage Subsystems.
SPECIAL INSTRUCTIONS:
This manual supersedes the previous edition, Revision 2, dated May 1974. This
edition includes Series 6000 disk storage equipment only. Since the contents of
the manual have been extensively revised, change bars and asterisks have not
been used.

PREFACE
This manual is a reference document providing hardware -oriented dese ripti ve and
instructive material for users of the DSS190 and DSS190B Disk Storage Subsysterrls and for
others concerned with their technical aspects. application, or operation. The basic
difference between DSSl90 and DSSl90B is the use of different disk pack drives. A physical
description of each type of disk pack drive is located in Section 1.
The manual is divided into three sections: Section I contains a general description of
the hardware used in the subsystem. including its performance specifications, capabilities,
and optional features. Section II contains a description of the specific functions performed
by the subsystem, including data formats, instructions, and status conditions. Section III
contains a description of the operator-accessible controls. switches, and indicators, and the
procedures necessary to enable personnel to operate the subsystem.

SECTION I
GENERAL DESCRIPTION
The Type DSSI90 and Type DSSI90B Disk Storage Subsystems are high-capacity disk
storage subsystems with advanced microprogramm.ed control and operating features that im-
prove time and throughput. This subsystem provides fast access and large capacity storage for
remote access, multiprocessing, and time sharing in m.edium to large data base systems.
SUBSYSTEM CONFIGURATION
The basic subsystem consists of a disk storage control (DSC) and two disk pack drives
using removable and interchangeable disk packs (see Figure 1-1). Storage capacity is
117,903,360 six-bit characters or 78,602,240 eight-bit bytes per disk pack (or 91,375,104
six-bit characters or 68, 531,328 eight-bit bytes using a basic: track format). This capacity
can be expanded by the addition of up to 16 devices (see Figure 1-2), or 32 devices for
maximtim online capacity using a single or dual subsystem (see Figure 1-3). Figure 1-4
presents a further expansion making use of a dual control subsystem with four simultaneous
channels.

Subsystem.s can be easily upgraded in the field by adding the various optional com.-
ponents available. This modularity makes it possible to provide backup com.ponents for
every module in the subsystem. with a maximum of versatility.
SUBSYSTEM COMPONENTS
Disk Storage Control (DSC)
The DSC is a general purpose microinstruction processor housed in a single low-profile
cabinet with an easily accessible operator panel (see Figure 1-5), or in the Integrated Control
Unit (ICU). The modular design of the DSC allows expansion and enhar ... cement of basic sub-
system capacity simply by installing optional hardware.
In addition to the operator panel, the DSC includes:
• A maintenance/configuration panel
• Forced-air cabinet cooling system
• Power supply and power control modules
• A basic disk channel with a link adapter interface to the external user
system (EUS)
• An Additional Drive Electronics, ADEI90. with a disk interface to the
disk pack drives. The disk interface can connect up to four disk pack
drives to the DSC

Options to the DSC include:
• A Dual Simultaneous Channel, DCH190 and DCB} 90B, consisting of one
basic disk channel, one Additional Drive Electronics (ADE190 and
ADE190B) and one data recovery module, for dual-channel crossbar
operation in which data can be transferred between the DSC and two
disk pack drives simultaneously.
• An Additional Data Channel, ADC190 and ADCI90B, provides a second
link adapter interface to the external user system (EUS) for transferring
data between the DSC and EUS on both interfaces, but not simultaneously.
One ADC 190 or ADC 190B may be applied to the DSC and one to the
optional Dual Simultaneous Channel, DCHl90 or DCHI90B.
• For two controls with single channels, a Dual Control Crossbar,
DCXl90 and DCXI 90B, and a disk Control Adapte r, CCA 190 and CCAl90B,
are required to provide crossbarring to all drives.
• For two controls with dual channels, DCH190 and DCH190B, crossbarring
is provided to all drives. (DCXI90 or DCXl90B is not required. )
Disk Pack Drives
The disk pack drive used by the subsystem is either the DSU190 or the compatible
DSU190B Disk Storage Unit. The DSU190 (Figure 1-6A) is an electromechanical disk pack
drive with a single mounting spindle housed in a low-profile cabinet. The DSU190B
(Figure 1-6B) is a single-spindle, moving-head disk pack drive, with associated Device
Oriented Electronics (DOE) housed in a single low-profile cabinet. Both disk pack drives
include easily accessible chambers for mounting the disk pack and convenient operator
control panels.
