Abstract
This technology brief describes the architecture and the implementation of major technologies in HP
ProLiant G6 c-Class Server Blades based on AMD Opteron™ processors. Much of the content of this
paper is similar or identical to the content of a companion paper about the technologies in HP
ProLiant G6 server blades based on Intel® Xeon® processors because many of the same technologies
have been implemented in both.
It is assumed that the reader is familiar with HP ProLiant server technology and has some knowledge
of BladeSystem architecture. For more information about the infrastructure components and complete
specifications of each server blade, see the HP website: www.hp.com/go/bladesystem/.
ProLiant c-Class server blade architecture
An HP ProLiant c-Class Server Blade is a complete server that slides into an HP BladeSystem c-Class
Enclosure. Three different c-Class enclosures are available to meet the needs of large or small IT
environments:
• The HP BladeSystem c7000 rack enclosure is 10U high and holds up to 16 ProLiant c-Class server
blades.
• The HP BladeSystem c3000 rack enclosure is 6U high and holds up to 8 ProLiant c-Class server
blades.
• The HP BladeSystem c3000 tower enclosure is designed with casters for sites without racks. It holds
up to 8 ProLiant c-Class server blades inserted vertically.
The rack enclosures fit in HP 10000 series racks and can operate with as few as one server blade
installed. The greatest advantage of blade architecture, however, is the ease of adding more server
blades. ProLiant c-Class server blades are built in standard form-factors, referred to as half-height (4U)
and full-height (8U). Both half-height and full-height server blades fit into any device bay in a
1BladeSystem c-Class enclosure.
ProLiant G6 c-Class server blades based on AMD Opteron processors include enterprise-class
technologies:
• Two or four AMD Opteron processors
• Thermal Logic technologies
• Advanced memory technologies
• Multiple slots for I/O cards
2• Integrated multifunction Ethernet network adapters that support TCP/IP offload engine (TOE) and
iSCSI acceleration
• Hot-plug internal disk drives
• Power management
Half-height server blades support up to 2 processors, 8 to 16 DIMM slots, up to 2 hot-plug or non
hot-plug drives, 1 dual-port integrated Ethernet adapter, and up to 2 mezzanine slots. Optional
mezzanine cards support multiple types of I/O fabric connectivity to the interconnect bays (Figure 1).

1 More information about BladeSystem c-Class enclosure configuration options can be found at
http://www.hp.com/go/bladesystem/.
2 TOE technology moves processing transactions from the main processor on a server blade to a processor
embedded on the network interconnect card. This frees the main processor for other work.

Because of their larger size, full-height server blades support up to 4 processors, up to 32 DIMM slots,
2 hot-plug drives, 2 dual-port integrated Ethernet adapters, and 3 mezzanine slots for optional I/O
cards. Full-height server blades also provide twice as much I/O bandwidth to the interconnect
modules as half-height server blades (Figure 2).

Processor technologies
ProLiant G6 server blades that support two AMD Opteron processors contain six-core 2400 Series
processors (Figure 3). ProLiant G6 server blades that support four AMD Opteron processors contain
either quad-core 8300 Series or six-core 8400 Series processors. AMD Opteron quad-core and six-
3
core technology delivers high performance and reduced latency for multi-threaded and multi-tasking
environments. All ProLiant G6 server blades with AMD Opteron processors use ServerWorks®
HT-2100 and HT-1000 chipsets.

AMD Opteron processors use Direct Connect architecture, which replaces the traditional front side
bus with an integrated memory controller, dedicated memory banks for each processor, and point-to-
point HyperTransport™ technology links between the processors, memory, and I/O chipsets. The
integrated memory controller supports PC2-6400 (DDR2-800) or PC2-5300 (DDR2-667) DIMMs.
AMD Opteron processors feature HyperTransport 3.0 technology (HT3), a parallel, point-to-point
interconnect that provides a direct, scalable bandwidth interconnect between the processors, the I/O
subsystem, and the chipset. However, current chipset technology supports HT3 only for inter-process
communication between processors, and not for I/O data. HT3 is an enhancement of HT1. It
increases the interconnect rate from 2 gigatransfers per second (GT/s) available on previous AMD
processors to a maximum of 4.8 GT/s. HT Assist™ r
