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
