Pentium II X eo n Processor Techn o logy

.

The P enti u m II Xeon processor uses t he same core architectu re as p revious Penti um II p rocessors ,

.

and it continues the same 32-bit technology line, which makes it fully software compatible with

.

all current Pentium Pro and Pentium II processors. Like the Pentium Pro and Pentium II

.

processors, the Pentium II Xeon uses dynamic execution techniques and a dual independent bus

.

structure. Th e dual independent bus structure provides a separate bus between the processor and

.

the s econdary level 2 (L2 ) cache. S ee the t echnol og y brief

100-MHz AGTL+ System Bus

.

An important enhancement is the move from the 66-MHz GTL+ bus used by the Pentium Pro and

.

Pentium II processors to the higher frequency 100-MHz AGTL+ bus. This provides faster data

.

pathways between t he processor and ran d om access memory (RAM), an d bet ween th e p rocessor

.

and system peripherals.

.

400- and 450-MHz Core Processor Frequencies

.

One of the most significant differences between the Pentium II Xeon processor and current

.

Pentium Pro processors is the much higher processor frequency. Pentium II Xeon processors,

.

currently at 400 MHz, are expected to reach 450 MHz by the end of 1998, and to incr ease beyond

.

450 MHz in later versions.

Larger Cache Sizes

.

The Pentium II Xeon processor supports larger L2 caches than previous Intel processors.

.

Pentium II Xeon processors are initially available in 512-KB and 1-MB configurations with future

.

plans for a 2-MB cache. I n cont rast, the Pen tium P ro pr ocess or ha s a max imum 1 - M B ca che.

.

The la rge r data c ach e provides a si gnificant performance boost, es pecially in s ym metric

.

multiprocessing (SMP) configurations and systems used in memory-intensive applications, such

.

as on-line transaction processing.

.

Full-Speed L2 Cache Bus

.

Previou s P enti u m II processors have a hal f-s p eed L2 cache bus that connect s the ca che mem ory

.

and the centr a l processing unit (CPU) core. Thi s mean s a 266-MHz Pentium II actual ly transfers

.

data between the L2 cache and CPU core at 133 MHz. In contrast, the Pentium II Xeon processor

.

has a full-speed cache bus, which means that a 400-MHz Pentium II Xeon processor transfers

.

data between the L2 cache and pr ocessor core at a full 400 MHz. The combination of the full-

.

speed cache bus and t he la rger cache size greatly enha nces the performa nce of th e P enti u m II

.

Xeon processor relative to the Pentium Pro and previous Pentium II processors, especially in

.

larger SMP configurations and memory-intensive applications.

.

Slot 2 Cartridge

.

Pent ium II processors ar e packa g ed in a s ingle edge con tact ( S EC) cartridge. The SEC ca rtridg e

.

for a Pentium II processor inserts into the Slot 1 connector on the motherboard, while the Pentium

.

II Xeon ’ s SEC cartridge inserts i nto the Slot 2 connector. The for m factor of the Slot 2 cartridg e

.

is larger than that of the Slot 1. Compared with the Slot 1 cartridge, the Slot 2 cartridge has

.

The lar g er cartridge and corres p onding mot herboa rd con nector for th e P enti u m II Xeon process or

.

require more pins. The additional pins on the Slot 2 cartridge provide support for a four-

.

processor (4P) multiprocessing system bus. Load and signal integrity modifications in the new

.

design allow a Pentium II Xeon processor to drive up to four main loads on the AGTL+ bus—

.

three other processors and a memory and I/O controller. This allows the Pentium II Xeon to scale

.

to 4P configurations. The extra pins also provide the additional power and ground connections

.

needed to support th e larger, full-speed L2 cache.

.

64-GB Cacheable Address Space

.

The Pentium II Xeon processor is able to access up to 64 GB of RAM; however, the memory

.

controller chipset determines the actual size of supported memory. Initial Pentium II Xeon

.

chipsets support memory configurations up to 8 GB.

.

MMX Technol ogy

.

The Pentium II Xeon processor supports MMX instructions, which allow certain applications to

.

operate on multiple data locations with a single instruction call to the processor. The MMX

.

functions are primarily used in multimedia applications such as audio and video manipulation;

.

however, increasing numbers of specialized business applications are being written to take

.

advantage of MMX capabilities.

industry-standar d benchma rks: the TPC-C benchmark test and the TPC-D version 1.3.1

.

benchmark test. The TPC-C benchmark measures performance in an on-line transaction

.

processing environment, while the T P C - D benchm ark repr es ents a broad range of decisi on

support (DS) applications that r equire complex, long-runnin g quer i es against large complex data

.

structures. Real-world business questions were written against this model, resulting in 17

.

complex queries.

Tables 1 and 2 show the configurations used for these benchmark tests and t he performance

.

results, which set new industry-wide performance levels for a single-node Intel-based system. For

.

Thermal Design

.

Compaq has designed an innovative thermal cooling solution for the Pentium II Xeon processor

.

that contributes to increased system reliability and future performance scalability to 8-way

.

archit ectures . Heat pipes transfer heat away from the Slot 2 cart rid g e thermal pla te to cooling

.

fins mounted atop the cartridge (Figur e 1).

.

This top-mounted position and the direction of the cooling fins are advantageous in two important

.

ways. First, this design cools efficiently regardless of the direction of air flow (vertical or

.

horizontal). Therefore, the same Slot 2 cartridge and heat sink combination used in the ProLiant

.

7000 4-way configuration can also be used in future 8-way configurations by simply reorienting

.

the p rocessor s. Second , because t he heat fins are top mou nted, th e redundant p rocessor p ower

.

module can be placed in its optimal position, next to the processor, to maintain short signal trace

.

lengths across the 100-MHz system bus (Figure 2). The resulting improvements to power supply

.

regulation and system bus signal quality increase system reliability. Moreover, the smaller

.

spacing between processor sockets makes possible future upgrades to 8-way Pentium II Xeon

.

archit ectures u s ing the same ch assis d esign.

ProLiant 7000 Architecture

The ProLiant 7000 ar ch it ecture all ows customers to scale the processor and memory subsystems to run their mission-critical applications. The following sections describe the ProLiant 7000 architecture—the processor board, memory expansion boards, input/output (I/O) board, and standard per i pheral board.

Processor Board

The p rocessor board (F i gure 2 ) ha s four sockets for Pentium II Xeon p rocessor s, four sock ets for redundant processor power modules, and two slots for memory expansion boards. The redundan t processor power modules maintain the precise voltage requirements of the processors. The memory expansion boards allow customers to scale system memory up to 8 GB. The ProLiant 7000 ships with one Pentium II Xeon processor, one redundant processor power module, and two memory expansion boards. Processor terminator cards are also provided with the server. A processor terminator card mus t rem ain in ea ch pr ocess or socket not occupi ed by a processor.

Memory Expansion Boards

The ProLiant 7000 ships with t wo memory expansion boards instal l ed on th e pr ocessor board. As shown in Figur e 3, each memory expansion board has si x teen m emory sockets ( four ban ks of four sockets) for Dual In-Line Memory Modules, or DIMMs. The DIMMs must be installed in sets of
