PREFAC E
This
manual
is
a
reference
document
providing
hardware-oriented
descriptive
and
instructive
material
for
users
of
the
DSSI90
and
DSSI90B
Disk
Storage
Subsystems
and
for
others
concerned
with
their
technical
aspects,
application,
or
operation.
The
basic
difference
between
DSSI90
and
DSSI90B
is
the
use
of
different
disk
pack
drives
A
physical
description
of
each
type
of
disk
pack
drive
is
located
in
Section
I.
The
manual
is
divided
into
three
sections:
Section
I
contains
a
general
description
of
the
hardware
used
in
the
subsystem,
includingits
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
DSSl90
and
Type
DSSI
90B
Disk
Storage
Subsystems
are
high-capacity
disk
storage
subsystems
with
advanced
microprogrammed
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
medium
to
large
data
base
systems.
SUBSYS TEM CONFIGURATION
The.
basic
subsystem
consists
of
a
disk
storage
control
(DSC)
and
two
disk
pack
drives
using
removable
and
interchangeable
disk
packs
(see
Figure
l—l).
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
l—Z),
or
32
devices
for
maximum
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.

Subsystems
can
be
easily
upgraded
in
the
field
by
adding
the
various
optional
com-
ponents
available.
This
modularity
makes
it
possible
to
provide
backup
components
for
every module in the subsystem with a maximum of versatility.
SUBSYST EM 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
enhancement
of
basic
sub—
system capacity simply by installing optional hardware.
In addition to the loperator panel, the DSC includes:
0 A maintenance / configuration panel
0 Forced-air cabinet cooling system
0 Power supply and power control modules
0
A
basic
disk
channel
with
a
link
adapter
interface
to
the
external
user
system (EUS)
0
An
Additional
Drive
Electronics,
ADE190,
with
a
disk
interface
to
the
disk
pack
drives.
The
disk
interface
can
connect
up
to
four
disk
pack
drives
to
the
DSC

Channel,
DCH190
and
DCHI9OB,
consisting
of
one
basic
disk
channel,
one
Additional
Drive
Electronics
(ADEIQO
and
ADE19OB)
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.
0
An
Additional
Data
Channel,
ADC190
and
ADC190B,
provides
a
second
link
adapter
interface
to
the
external
user
system
(EUS)
for
transferring
data
between
the
DSC
and

on
both
interfaces,
but
not
simultaneously.
One
ADC190
or
ADCI9OB
may
be
applied

the
optional
Dual
Simultaneous
Channel,
DCH190
or
DCH190B.
o
For

channels,
a
Dual
Control
Crossbar,
