Powerful, Low Cost Hardware Design

HP Precision Architecture-RISC
The HP 3000 CS 99x business computers use HP's Precision
Architecture RISC (PA-RISC) technology to provide high
performance and reliability at a low cost.

PA-RISC is built upon Reduced Instruction Set Computing (RISC)
principles, a design approach that delivers greatly simplified
computers that are optimized to provide the highest performance
for a given integrated circuit technology.  The inherent
simplicity of PA-RISC implies that computer systems can be
implemented with fewer components to achieve vastly superior
reliability when compared to older Complex Instruction Set
Computer (CISC) systems.

At the core of PA-RISC is an instruction set containing 140
carefully selected, fixed format instructions.  Because the
instruction set is simplified, instructions can be hard-wired
directly into the CPU.  Hard-wiring eliminates microcode and the
necessity to decode complex instructions.  This allows the
processor to operate at maximum performance.

PA-RISC utilizes a load/store design and register-to-register
operations to reduce the number of memory accesses.  To further
enhance performance, optimizing compilers schedule instructions
and manage the instruction pipeline.  With hard-wired control, a
load/store design, and optimizing compilers, instructions can be
executed on virtually every clock cycle.  Single cycle
instructions account for much of the superior performance of PA-
RISC.

As one of the first major vendors to deliver a RISC-based system,
Hewlett-Packard is one of the leading manufacturers of RISC-based
computers today.

VLSI Technology Leadership
PA-RISC was designed to provide user benefits independent of the
particular semiconductor technology implementation.  HP's use of
submicron CMOS Very Large Scale Integration (VLSI) technology
allows the entire CPU, Translation Lookaside Buffer (TLB) and
floating point coprocessor to be integrated onto a single chip.
Up to two processor modules and associated caches are implemented
on a single printed circuit board.  Reduced complexity allows
fewer components and higher reliability, and a resulting lower
cost base.

Low Cost of Ownership / Small Footprint
Traditionally, business computers of this power have made use of
liquid cooling.  Mainframe vendors supplying older technology,
CISC-based systems, use hundreds of chips and components so
closely packed that they are at risk of overheating unless liquid
cooling is used.  The HP 3000 Corporate Business System's
advanced RISC-based VLSI allows use of CPU technologies that
provide very high performance without the complexity that creates
the need for liquid pumps and exorbitant tubing.  This results in
a system that has 1/12 the footprint of traditional mainframes,
requires much less complex site preparation and maintenance, and
is significantly less expensive to produce, own and operate.

Designed For Growth
The Corporate Business Systems were designed from inception to
allow for future scalability and expandability.  For example, the
Corporate Business System 99x has a virtual address capability
with an addressing range of 256 Tbytes, allowing for substantial
expandability to meet growing software requirements.  In
addition, the hardware architecture is designed to handle higher
degrees of multiprocessing, including 12- and 16-way, and to
capitalize on emerging technologies such as processor redundancy
and fault tolerance.

Symmetric Multiprocessing
The HP 3000 Corporate Business System currently supports tightly
coupled, symmetrical multiprocessing of up to eight processors.
Multiprocessing (MP) allows for economical, modular growth of
processing power as system performance requirements increase.
Multiprocessing in the MPE/iX software environment is entirely
transparent to the application, end users and system
administrators.  This means that existing applications can
benefit from the increased MP system performance without having
to execute any rewrites or modifications.  In addition, MP
provides increased system availability.  If one CPU fails, MPE/iX
notes the failure upon reboot, deconfigures the failed processor,
and continues normal boot and operation.

In-Cabinet Processor Upgrades
Add-on processor modules and simple processor board replacements
allow you to grow your CS 99X system from one performance level
to another.  Through an easy processor addition today and/or a
future processor upgrade tomorrow, you can increase your system
performance, protecting your initial investment in the HP 3000
Corporate Business System.

Virtual memory
The PA-RISC architecture allows for virtual address of 64 bits.
The CS 99x implements virtual addresses of 48 bits in length,
ensuring ample expandability to meet your growing software needs
of today.  Virtual memory is divided into 65,535 spaces with each
space 4 Gbytes in length.  Spaces are further divided into fixed-
length 4 Kbyte pages, with a page holding either code or data.  A
single data structure can be up to 1 Gbyte in length and the
virtual memory scheme can accommodate memory of more than 260,000
Gbytes.

Virtual-to-physical address translation is done by the
Transaction Lookaside Buffers (TLB) that cache recently accessed
virtual page translations and convert the 48-bit virtual address
into a 32-bit physical address.  When virtual addresses are
missing from the TLB, the CS 99x has a hardware assisted TLB miss
handler which reduces the software overhead associated with
handling these misses resulting in higher system performance.

All HP 3000 high-end systems provide page-level access
protection, and the TLB hardware supports protection mechanisms
to ensure that the currently executing process has sufficient
authorization to perform the requested data, code, or I/O access.

Advanced Processor Technology

Cache
The use of cache memory enhances system performance by minimizing
CPU requests for instructions or data stored in memory.  By
storing frequently used instructions and data in a high-speed
cache memory instead of relying on system memory, the CPU can
execute instructions or process data without overloading the
Processor Memory Bus.  This is particularly important for
multiprocessor systems.

The HP CS 99x processor board uses a 1 Mbyte instruction cache
and a 1 Mbyte data cache per processor module.  These caches
operate in a write-back mode.  Write-back means that the cache
writes modified data to system memory only when the processor
needs the cache location for other data or when the operating
system flushes the cache location due to a direct memory access
operation.  This efficient cache operation provides maximum
system throughput.  Parity checking protects the cache to insure
that there is no undetected data corruption.

Instruction Pipelining
Instruction pipelining is a technique that overlaps instruction
processing so that one instruction can begin to execute before
the previous one has finished.  The net effect is that one
instruction completes with essentially every instruction clock
cycle.  The efficient use of pipelining greatly increases system
performance.  The HP 3000 CS 99x systems utilize five-stage
pipelines with fast 11.1 nanosecond cycle times.

Floating Point and Superscalar Operation
Single and double precision floating point calculations are
performed by an on-CPU chip floating point coprocessor (FPC).
The coprocessor significantly decreases the time required to
perform floating point calculations.  Superscalar operation is a
technique that allows floating point operations to be executed
concurrently with other non-floating point operations in the same
instruction cycle.  The next effect of superscalar operations is
greater systems performance for floating point applications.

System Organization

Memory and I/O subsystems
The HP 3000 Corporate Business System uses 4 Mbit dynamic RAMs
and is expandable in 64, 128 and 256 Mbyte increments.  Up to 2
Gbytes of main memory are supported.  Refer to the Table of
Specifications for specific memory sizes.

The HP 3000 CS 99x has a mainframe-class bus structure which
provides high system throughput to handle very heavy processing
and I/O demands.  This bus structure is two-tiered to provide an
optimum balance between processor and I/O requirements.  An
important augmentation to system hardware performance is MPE/iX's
ability to reduce disk I/O significantly when compared to
traditional mainframes.  MPE/iX employs an improved disk caching
capability referred to as "mapped files", which enables the
system to take advantage of large memory sizes to increase
performance in I/O intensive applications by using main memory as
a buffer for disk.  This ability to minimize disk I/O is a
crucial factor in providing responsive systems for critical
application processing, and provides our customers with a
competitive advantage by improving system performance without
costly peripherals or complex system administration.

High speed Processor Memory Bus
Central Processing Units access main memory over a 1 Gbyte/second
(peak) high-speed Processor Memory Bus (PMB).  Its separate
address and data paths have been designed to maximize speed and
throughput of memory bound transactions.  Additionally, the PMB
was designed to minimize bus contention for high-performance
multiprocessing applications by having special hardware to ensure
processor cache coherency.  The bus speed and cache coherency
hardware allow for efficient performance scaling for
multiprocessing applications such as OLTP.

HP-Precision Bus
The HP-Precision Bus supports I/O expansion cards for interfacing
to peripheral devices and providing data communications
functions.  The PMB supports up to 8 HP Precision Busses (HP-PB)
through separate dual bus converters.  One dual bus converter
connects to two HP-PBs.  The Precision Bus provides a 32-bit data
path and can support a peak data transfer rate of 32 Mbytes/sec.
In the maximum Precision Bus configuration, aggregate I/O
throughput is 256 Mbytes/sec.

Peripheral connections
Disks are connected via Precision Bus Fiber Optic Link interfaces
(PB-FL), which support up to eight disk drives each.  Disks,
tapes and system printers can be connected either via an industry
standard SCSI channel card or a Precision Bus Adapter Interface
Bus (PBA-IB) channel card which supports the 8 bit wide, IEEE-488
standard Hewlett-Packard Interface Bus (HP-IB).  One SCSI channel
card is integrated into the system and provides connection for up
to seven peripheral devices.  One PB-FL is integrated into the
system for support of up to eight disk drives, and one PBA-IB is
included for support of up to 6 peripheral devices.  In addition
to peripheral interface cards, the HP-PB card cage supports
Programmable Serial Interface (PSI) cards, allowing HP 3000 99x
systems to be linked to other computers in a distributed
computing environment, and an 802.3 Local Area Network Interface
Channel (LANIC) for system-to-system datacommunications.  A
Corporate Business System with a full complement of card cages
supports a maximum of 40 PB-FL cards, 40 SCSI cards, 16 PBA-IB
cards or 8 PSIs.

Workstation and serial printer connection
Connections for workstations, serial printers and other serial
devices are provided via Datacommunications and Terminal
Controllers (DTCs) that are distributed over an IEEE 802.3
standard Local Area Network (LAN).  This flexible connection
scheme allows DTCs to be situated in the department that they
serve, saving the cost and effort of running cables from the
system processing unit to each workstation.  The DTC72MX can
support up to 72 direct or modem connected ports while the DTC16
can support up to 16 direct or modem connected ports.  A
LAN/Console card is integrated into the system for connection to
the DTC LAN, connection to the system console and system-to-
system datacommunications, if desired.

PCs can also be connected to the HP 3000 through HP LAN Manager
and Novell Netware LANs.  Physical connections can be via HP
EtherTwist which is a local area networking scheme using
unshielded twisted pair (or phonewire).  Both workstations that
are connected via a DTC, and PCs that are connected via a LAN can
communicate with HP 3000 systems and servers sharing the same
LAN.

Systems Management

The HP 3000 Corporate Business Systems have robust functionality
for managing large data center environments.  Available from
Hewlett-Packard and its third party partners is a wide variety of
systems management solutions in the areas of performance
management, system accounting and configuration, security,
availability, operations control and storage management.

HP OpenView Systems and Network Management
HP OpenView System Manager provides a flexible, integrated
approach to systems and network management and a consistent
management framework for an organization's entire network of
information and computing resources.  Through exception-based
system management, operators are notified of system events
graphically and automatically by the HP OpenView network map.
Operators can define which events to report, providing
flexibility and eliminating unwanted notifications.  The HP
OpenView console is a version of HP OpenView System Manager that
provides the benefits of OpenView for a single HP 3000 system.
Task-based filtering of events lets the operator focus on
specific categories of messages all at once, e.g.  all tape
messages or all printer messages, and an automatic response
feature brings the system one step closer to being self-managing.
The HP OpenView console is standard on the DX version of the
Corporate Business System.

High Availability
The HP 3000 Corporate Business System meets the high availability
requirements of mission critical applications through a variety
of hardware and software elements.  The system features error
correction for the system bus and main memory, memory page
deallocation, redundant I/O channels, and power protection using
HP PowerTrust UPSs.  Memory page deallocation automatically
detects and corrects memory failures.  The memory is scanned and
corrected in background mode and if not correctable, the bad page
of memory is deallocated on-line by the system without
interrupting applications.  In the event of a power loss, the HP
PowerTrust UPS provides power protection for the system.  If AC
power is lost, the state of the processor is secured in memory
for at least 15 minutes with no loss of data.  If all elements of
the system are protected by HP PowerTrust UPSs, operation can
continue during this 15 minutes allowing for orderly system
shutdown.

Hardware redundancy also extends to on-line storage since HP disk
arrays can provide RAID-3 level data protection for disk
mechanisms.  Mirrored Disk/iX provides an even higher level of
system availability through redundancy of I/O controllers, disk
mechanisms, power supplies and cabling.  SPU Switchover/iX
detects system failures and allows for switchover from a primary
to a secondary processor in the event of a processor failure.

Unplanned downtime due to software failures can be minimized by
using AutoRestart/iX, Threshold Manager/iX and/or TurboSTORE/iX
II.  AutoRestart/iX will immediately save the system state after
a software failure and automatically restart the system.
Threshold Manager/iX, specifically developed for the Corporate
Business Systems, monitors vital system tables which if depleted,
could cause a system failure.  If a failure mode is anticipated,
Threshold Manager/iX warns the operator and limits the system
usage until the vital resource is out of danger.  System
availability can be further improved by TurboSTORE/iX, which
provides high speed, unattended, on-line backup.  TurboSTORE/iX
II and AutoRestart/iX are standard on the DX version of the
Corporate Business System while Threshold Manager/iX comes
standard with all Corporate Business Systems.

Performance Management
HP GlancePlus, a performance monitoring and diagnostic software
tool for the HP 3000, provides information on current system
resource usage and process activity to help system managers and
operators quickly isolate and resolve performance bottlenecks
when they occur.  HP LaserRX software provides the comprehensive
system activity information needed to manage your HP 3000 system
for optimal performance, helping to contain costs, streamline
data processing operations, and efficiently deliver defined
levels of service.  RXForecast works with LaserRX to support
ongoing capacity planning and to allow you to perform regular
system resource forecasting.  All three of these performance
management tools are standard on the DX version HP 3000 Corporate
Business System.

Security
Operating system security is an essential component of systems
management.  To protect your system from unauthorized access and
data corruption, the HP 3000 provides robust system security.
The operating system is designed so that the user capabilities,
the account structure, the file system, and system security are
integrated.  Every file and device can optionally have an access
control definition (ACD), which specifies which users have access
to that file or device.  An ACD can restrict read, write, and
append access, and can restrict printing access to a particular
device, to a specific user or set of users.  System security is
further augmented with multi-level logon access security and
auditing.  Security Monitor/iX, shipped standard on the DX
version of the HP 3000 Corporate Business System, can be used to
provide further protection against unauthorized access to
sensitive data and system resources through stronger password
protection, improved audit trails, tighter access security and
the monitoring of security breaches.

Open Systems Functionality

All HP 3000 900 systems provide OLTP performance and
functionality while also supporting industry and de facto
standards.  The HP 3000 provides interoperable networking (ARPA,
OSI and IBM SNA services) and application portability through
