HP ProLiant DL585 Server Technology - Technology Brief

ProLiant DL585 architecture

The ProLiant DL585 server is a powerful, 4U enterprise server incorporating technologies that

extend the capabilities of industry-standard x86 computing. This server provides high

performance and the capability of running both 32-bit and 64-bit applications

simultaneously with no performance penalty when using an operating system that supports

64-bit extensions. This is possible because the x-86-64 instruction set architecture is a super-

set containing the x86-32 instruction set architecture.

For the ProLiant DL585 server, HP designed a new system architecture that supports Opteron

processors and other advanced technologies that enterprise customers have come to

expect from ProLiant servers. The ProLiant DL585 is the first links-based x86 server platform. It

provides excellent system performance by using powerful processors, on-chip memory

controllers, a large memory footprint, and processor-to-processor communication to

significantly reduce latency. Figure 1 is a block diagram of ProLiant DL585 architecture.

The essential features of the ProLiant DL585 architecture include:

• AMD Opteron 800 series, single-core or dual-core processors and the AMD-8000™ series

chipset supporting up to 1 GHz HyperTransport™

• Embedded memory controllers and 144-bit wide memory bus

• AMD-8111 HyperTransport I/O hub (south bridge)

• Eight full-length, 64-bit PCI-X I/O slots
