Introduction

TheMSU0402IMSU0451 MassStorage

Units

are

high-capacity

disk

storage

sub-

systems

with

advancedmicroprogrammedcontrol

and

operating

features

that

improveresponse

time

and

The

MSU0402 is

identical

in

appearance

and

operationto

the

MSU0451

and

may

befield-upgraded (see Options)to

an

MSU0451.

Up

to32

are

controlledbyphysically

is

ensured

by

are

detected.

• Powerfaultsensing-

If

ensured

by

Introduction

Physically,

the

MSU0402

and

MSU0451

disk

packs

are

the

same.

The

logicalfile

formatsfor labels,T&Ds,

and

alternate

are

different,therefore,

disk

interchanged

between

the

MSU0402

and

The

used

on

the

requires

reformatting

The

are

as

•

Eases

Installation

ofMSU0451s

can

be

staggered,

ortwo

disruption.

1-3

AT71-03

Introduction

• Combines

the

lowerprice-per-character

advantage

of

the

MSU0451

with

the

performance

advantage

(faster

accesstime)

of

the

MSU0400.

Storing

of

a

smaller

number

of

files

on

the

MSU0400 also

results

in

less

arm

contention

to

high-acti

vity

files.

• Allowscontinued

use

of

previously

purchased

disk

packs.

The

smaller-

capacity,less-expensive MSU0400

disk

pack

can

be

used

as

removable

media

during

new

program

and

file debugging.

The

MSU0402/0451

can

also

be

intermixed

with

MSU0500. Additionally,

MSU0451

can

be

intermixed

with

MSU0501. (See

are

the

prereq:uisitesfor

proper

disk

handling:

• Always

keep

a

disk

pack

in

its

carrying

whenever

it

is

not

drive.

•

The

bottomcover

of

the

disk

pack

carrying

case

may

beremoved

easily

by

squeezing

the

latch

on

the

bottomcover;

the

topcoverisdesigned

so

that

it

can-

not

until

the

disk

pack

is

mounted

on

the

spindle.

• Alwaysreassemble

even

when

the

disk

pack

is

not

inside.

• N

ever

touch

mating

surface

with

anything.

•

Do

not

exposea

disk

pack

to

stray

magnetic

fields, excessive

pressure,

or

sharp

impact.

•

Return

every

disk

pack

to

its

own

carrying

case.

• N

ever

store

a

disk

pack

where

the

temperature

exceeds

the

limit

of60°F-90°F

(15°C-32°C).

If

the

limit

has

been

exceeded,

keep

the

disk

in

the

fortwo

hours

before

it

is

used.

•

Store

a

disk

pack

in

an

environment

identicalto

environment.

• N

ever

MassStorageProcessors

The

mass

storage

processorsfor

the

MSU0402/0451

are

microprogrammed

periph-

eral

processors

that

connectto

the

central

processor

via

high-speed

110

channels

and

relieve

the

central

processor

system

of

all

device-orientedfunctions.

The

mass

storageprocessorsfor

the

MSU0402/0451

are

listed

in

Table

A-I.

Components

The

mass

storageprocessorsconsist

of

the

followingcomponents (see

Figure

A-I).

• Read-Only

Memory-

providesaccess

and

storageto

resident

control

and

diag-

nosticmicroprograms.

• Microprocessor-

interprets

all

the

microinstructions

and

performs

their

specifiedoperations.

• Scratchpad

memory-

provides

temporary

storagefor

data

buffering

param-

eters

and

commandstorage.

• PeripheralSubsystemInterface (PSI)

Control-

provides

the

logic

and

buffering

necessaryto interface

with

the

one-byte-wide

PSI

to

sustain

data

transfer

and

controldialogs.

• DeviceLevelInterface(DLI)

Control-

provides

the

logic

and

bufferingneces-

sary

to interface

with

DLIs

to

sustain

data

transfers

and

controldialogs

in

addi-

tion

to verificationinformation
