Abstract

This technology brief describes the key technologies implemented in Intel-based HP ProLiant 100-series
G6 servers. The 100-series family includes the ProLiant DL100-series, the ML100-series, and the
DL1000 Multi Node architecture. As of this writing, the Intel-based 100-series G6 servers include the
ProLiant DL120, DL160, DL180, ML110, ML150, DL170h, DL2x170h, and DL4x170h. Links to the
QuickSpecs for each of these servers are listed in the "For more information" section at the end of this

technology brief.

Introduction

HP ProLiant G6 servers have been the focus of extensive engineering and development.
Characterized by increased performance, better power efficiency, and more powerful management
tools, the servers include these new technologies:
• The Intel® Xeon® Processor 5500 Series
• The Intel Xeon Processor 3400 Series
• Double Data Rate-3 (DDR-3) memory DIMMs
• Thermal sensors incorporated throughout the ProLiant100-series G6 servers
• ProLiant Onboard Administrator Powered by Lights-Out 100i (LO 100i)
• I/O technologies such as PCIe generation 2 (PCIe 2.0) and faster Smart Array controllers that
incorporate common form factor components
• "Right Size" Common Slot power supplies in multiple sizes to provide the required amount of power
and improve power efficiency
• Management options accessed from the BIOS setup utility that can reduce power and thermal use
by power supplies, I/O, processors, and memory
The technologies discussed in this paper are implemented in all Intel-based ProLiant 100-series G6
servers. Exceptions are noted where different levels of technology implementation or service exist
among individual ProLiant 100-series G6 platforms.

Intel Xeon 5500 Series processor technology

Some ProLiant Intel-based 100-series G6 servers contain the Xeon 5500 Series processors. The
processors include an integrated memory controller and Intel QuickPath technology to boost
bandwidth between processors, memory, and I/O subsystems. Three memory channels from each
integrated memory controller to its dedicated memory provide a total bandwidth of 32 gigabytes per
second.
The Xeon 5500 Series microarchitecture is built on hafnium-based, 45 nanometer high-k metal gate
silicon technology to reduce electrical leakage. These small, energy-efficient, high-performance
processors support distributed shared memory, Intel Hyper-Threading technology, and Intel Turbo
Boost Technology with Intelligent Power Technology.
