Processor technologies

HP BladeSystem ProLiant G5 c-Class server blades use multi-core technologies from Intel and AMD. A

multi-core processor has two or more separate execution cores on one or more physical dies so that it

can perform more work within a given clock cycle. To take advantage of multi-core processing,

software must be multi-threaded to distribute the work across multiple execution cores.

Intel-based ProLiant G5 server blades use one of the following processor chipsets:

• Intel 5000P chipset (5200, 5300, and 5400 Series)

• Intel 7300 chipset (7300 and 7400 Series)

Depending on the server model, ProLiant G5 server blades contain either Intel Xeon 5000 Sequence

or 7000 Sequence processors based on the Intel Core™ microarchitecture. They use less power and

produce less heat than previous-generation Intel processors. To avoid saturation of the front side bus

(FSB), the Intel 5000 chipsets widen the interface by providing dual independent buses. Intel Core

microarchitecture features additional technologies that improve per-watt performance and energy

efficiency: Hardware Virtualization, Enhanced Intel Speed-Step® Technology, Supplemental

Streaming SIMD Extension 3 (SSSE3), and Intel Execute Disable Bit technology.

ProLiant G5 server blades with two Intel processors use the Intel 5000P chipset. This chipset contains

two main components: the Memory Controller Hub (MCH) and the I/O controller hub. The

Northbridge MCH supports DDR2 fully-buffered DIMMs.

The 64-bit Intel Xeon 5200 Series processors have two complete processor cores, including caches,

buses, and execution states. The Xeon 5200 Series processors operate at a maximum frequency of

3.33 GHz (1333 MHz FSB), with 3 MB of L2 cache per core (6 MB total).

Intel Xeon 5300 and 5400 Series processors were the first quad-core processors for dual-socket

platforms (Figure 4). Each Xeon 5300 and 5400 Series processor has two dual cores that share L2

cache. The 5300 processor operates at a maximum frequency of 3.0 GHz (1333 MHz FSB) with a

total of 8 MB of L2 cache. The 5400 processor operates at a maximum frequency of 3.16 GHz

(1333 MHz FSB) with a total of 12 MB of L2 cache.
