Executive summary

For many types of computing, systems based on the Intel

Itanium

2 processor offer markedly superior

performance over other systems that utilize RISC or IA-32 processors—while still maintaining a very competitive

price. The HP Integrity rx1600, rx2600, rx4640, and rx5670 servers deliver price/performance that has

changed the 64-bit server market.

The Integrity rx1600, rx2600, rx4640, and rx5670 servers utilize the HP-designed Scalable Processor Chipset

zx1, which integrates the Intel Itanium 2 processor with industry-leading high-bandwidth and low-latency

connections to memory and I/O. HP continues to prove the Intel Itanium architecture concept of highly parallel,

64-bit performance with a line-up of servers that are full featured, have a unique high-bandwidth system

architecture, and use industry-leading commodity parts to ensure compatibility and economical pricing.

This white paper provides details about these HP Integrity servers, shows their features and benefits, discusses

their electrical architectures, and provides a breakdown of their unique high-availability features. What’s more,

this paper illustrates how HP simplifies the transition from RISC and IA-32 while preserving an IT user’s investment

in existing software.

Introducing the Intel

Itanium

2 processor

The Intel Itanium 2 processor is a milestone in the continuing evolution of microprocessors because it is the first

enterprise-class 64-bit processor that has the power to become pervasive. Let’s take a closer look at what this

means.

Today, 32-bit servers or proprietary 64-bit RISC servers are the norm. They have respectable price/performance

ratios but are either fundamentally limited in performance scalability or are exceedingly expensive.

Servers based on the Intel-architecture 32-bit (IA-32) processors, for example, are unable to address large

amounts of memory efficiently. Meanwhile, 64-bit RISC architectures have the necessary performance and

addressing, but they are more expensive and generally lock the customer into a proprietary operating

environment and a single computer vendor. End users and IT professionals alike are clamoring for high

performance and large addressing at an economical price. And they also are asking for pervasiveness so that

they do not have to deal with multiple architectures and complexity.

HP and Intel co-developed the Intel Itanium 2 microarchitecture. The result is a high-performance, parallel 64-bit

architecture that has the performance headroom to grow in the future and can be priced at a level to ensure its

widespread adoption. The Intel Itanium 2 microarchitecture fulfills both of these promises and is likely to become

pervasive very quickly. The Intel Itanium 2 processor is the fundamental building block of the entry-level

HP Integrity rx1600, rx2600, rx4640, and rx5670 servers.

Itanium 2–based HP Integrity rx1600, rx2600, rx4640, and

rx5670 servers

Itanium 2–based servers from HP are targeted at performance-hungry markets such as technical and scientific

computing, Secure Sockets Layer (SSL) Web serving, application serving, and database applications. What’s

more, these systems are highly affordable, making them extremely attractive to software developers. Read on to

learn about the system features that fulfill these promises.

HP Integrity rx1600 server at a glance

The HP Integrity rx1600 server uses the Low Voltage Intel Itanium 2 processor in a slim, 1U (3.5-inch height)

system package. It provides industry-leading performance in a dense form factor. The Low Voltage (LV) Intel

Itanium 2 processor delivers industry-leading $/FLOPS for compute-intensive workloads, at lower power levels,

where space is at a premium. The HP Integrity rx1600 server supports up to two 1.0 GHz LV Intel Itanium 2

processors with 1.5 MB of on-chip L3 cache and as much as 16 GB of RAM. This means that it has extraordinary

compute density. Fitting 41 servers into a 2-meter rack delivers an astounding 320 gigaFLOPS of potential

power.

The Integrity rx1600 server also leverages the same management features as the Integrity rx2600 server. It is

ideal for compute-intensive server farms in the high-performance technical and scientific computing markets, and

it is a perfect fit for the network edge, security, and software engineering fields. Features such as memory chip
