and Compaq have continued a two-decade-long partnership to deliver one of the most
. .
stable and reliable industry-standard computing platforms in the market by working hand
. .
. .
in hand to develop the Windows 64-bit server family. Aside from the tight integration
. .
work with Intel and Microsoft, Compaq has been collaborating with independent software
.
. .
.

. .
.
applications on the new ProLiant platform.
. .
. .
. .
The ProLiant DL590/64 server represents the official entry from Compaq into the world
.
. .
of high-performance industry-standard 64-bit computing. With this introduction of the
. .
Itanium-based server, Compaq strengthens its enterprise product portfolio by delivering
.
. .
an industry-standard platform with enterprise-class performance.
.
. .
. .
This technology brief gives an overview of 64-bit computing. It explains the technologies
.
. .
implemented in the ProLiant DL590/64 server and describes development efforts Compaq
. .
.
. .
has taken to ensure that reliable and stable 64-bit solutions are available.

- Page 3 ECHNOLOGY RIEF (cont.) 6 4 - B O M P U T I N G V E R V I E W At its simplest level, 64-bit processing means the registers and execution units within the processor can access addresses and manipulate data that are 64 bits wide. Although 32-bit microprocessor architecture has 64-bit data paths, its internal registers and execution units only access addresses and manipulate data that are 32 bits wide.
- Page 4 ProLiant DL590/64 Server Architecture The ProLiant DL590/64 server is Compaq’s first Itanium-based product. The architecture (Figure 1) uses the Intel 82460GX chipset. The chipset includes a 133-megahertz (MHz) front-side bus that uses both edges of the clock cycle to produce 266 megatransfers per second and supports dual memory boards and up to four Intel Itanium processors.
- Page 5 ECHNOLOGY RIEF (cont.) In addition, the floating point performance of Itanium processors is significantly better than that of today’s IA-32 processors. The Itanium processor has two extended-precision and two single-precision floating point units, capable of executing up to four extended-precision or eight single-precision floating point operations per clock cycle.
- Page 6 Memory is expandable, four DIMMs at a time, to a maximum total of 64 GB. Compaq strongly recommends using DIMMs supplied by Compaq because of the rigorous testing they undergo in ProLiant systems. However, the ProLiant DL590/64 supports industry-standard 168-pin PC100 CL2 ECC Registered DIMMs with some restrictions .
- Page 7 ProLiant DL590/64 server. Compaq also required that these connectors be placed on one side of the board. This enhances cooling by allowing the processor board to plug into a side plane instead of a midplane, which would restrict front-to-back airflow.
- Page 8 ECHNOLOGY RIEF (cont.) Figure 6: Compaq designed the ProLiant DL590/64 server's I/O board. Distributed Power System Historically, most ProLiant servers have been powered by one or more AC-to-DC, multiple output power supplies. Power from the power supplies is cabled or routed to all components of the server.
- Page 9 A lightly loaded ProLiant 590/64 server may operate satisfactorily using low-line power; however, if low-line power is used, redundancy of the power supplies may be sacrificed and the server power demand may exceed the total amount of power available. Compaq strongly recommends using high-line power to operate ProLiant DL590/64 servers when possible.
- Page 10 A second fan (Figure 9) was designed to cool the system power modules, media bay, and PCI area of the server. Engineers modified an existing Compaq fan design so that it could be hot plugged from the top and placed in an optimal position to cool these components. The ProLiant DL590/64 server uses four of these hot-pluggable, redundant 6-inch fans.

Page 11: Pci Hot Plug Technology
The ProLiant DL590/64 server incorporates industry-standard PCI Hot Plug technology. This technology, pioneered by Compaq, adds hot-plug capabilities to existing PCI adapters for increased system availability and serviceability. Compaq led the industry by licensing its PCI Hot Plug implementation, thus broadening customer access to this industry-standard technology. -
Page 12: Redundant Power System
ECHNOLOGY RIEF (cont.) Redundant Power System The power subsystem in the ProLiant DL590/64 server is completely redundant. Redundant line cords allow customers to provide two AC feeds to the server from different power grids (see Figure 10). The line cords connect to a switch in the back of the server that senses when AC power from the primary feed is beginning to fail. -
Page 13: Redundant Hot-Plug Fans
ECHNOLOGY RIEF (cont.) Figure 12: Three redundant, hot-plug system power modules provide DC power to the server’s components. The primary power supplies and their associated system power modules are N+1 redundant and load balancing. Two primary power supplies and system power modules can support a fully loaded ProLiant DL590/64 server;... -
Page 14: Integrated Smart Array Controller
ECHNOLOGY RIEF (cont.) Integrated Smart Array Controller The ProLiant DL590/64 server is equipped with an integrated Smart Array controller (Figure 13). The integrated controller, also known as RAID on a chip, or ROC, is an embedded hardware-based RAID solution that enhances system reliability and improves host processor utilization. It is ideal for data center servers where internal storage is optimized for OSs and swap space. - Page 15 ECHNOLOGY RIEF (cont.) The Array Configuration Utility is provided for more advanced configuration support. The Array Configuration Utility is an easy-to-use graphical configuration utility to help users set up and change the drive array configurations. It can be used to configure the standard internal drive controller as well as any optional controller boards that are installed.
- Page 16 ECHNOLOGY RIEF (cont.) An accessible side plane eliminates the need to replace the system board when SCSI, video, memory, or port repairs are needed. Thumbscrews, easy access panels, and board release levers allow quick access to modular, removable, hot-plug components. The ProLiant DL590/64 server power subsystem was designed for quick and easy maintenance.

- Page 18 To take advantage of the full performance capabilities of the Itanium processor, customers will need to run 64-bit OSs. Compaq will support the use of 64-bit versions of Windows Advanced Server, Limited Edition (Windows Enterprise Server in the .NET production version), Red Hat Linux 7.2, and SuSE Linux Enterprise Edition.
