Abstract The HP ProLiant DL585 server is a 4U rack-optimized, 4-way server created for large data center deployments requiring enterprise-class performance, uptime, and scalability, plus easy management and expansion. Based on AMD™ Opteron™ technology, the ProLiant DL585 server greatly improves the performance of standard 32-bit applications. Moreover, it includes AMD 64-bit extensions that add the capability to run 32-bit and 64-bit applications on the same x86 platform with no performance penalty.

Introduction The Opteron-based ProLiant DL585 server is a 4-way, x86 rack-optimized server delivering best-in-class performance, industry-leading management, and enterprise-class reliability for large data center deployments. The DL585 is a 4-way platform for high-performance 32-bit and 64-bit computing requirements. This capability allows IT organizations to protect their large x86 investments and manage their 32- to 64-bit transition.

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.

AMD-8000™ series chipset The ProLiant DL585 server uses the AMD-8000 series chipset with Direct Connect Architecture and HyperTransport™ technology. HyperTransport is a parallel point-to-point interconnect that replaces parallel front-side bus technology. Direct Connect architecture is AMD’s designation for the coherent HyperTransport connection between processors.

In the ProLiant DL585, processors access the memory controllers at core speed. Each onchip memory controller directly accesses the DIMMs on the same processor/memory board at the DIMM speed. The aggregate bandwidth for locally accessed memory increases with the number of processors. The Opteron chipset supports dual-channel memory, which reduces memory latency by increasing the bus width from 64 bits + check bit to128 bits + check bits.

• Node interleaving (SUMA) breaks memory into 4-KB addressable entities. Addressing starts with address 0 on node 0 and sequentially assigns through address 4095 to node 0, addresses 4096 through 8191 to node 1, addresses 8192 through 12287 to node 3, and addresses 12888 through 16383 to node 4. Address 16384 is assigned to node 0 and the process continues until all memory has been assigned in this fashion.

ProLiant DL585 PCI-X slots Performance balancing is the paired arrangement of expansion boards for optimal performance based on the bus architecture of the expansion slots. Properly balancing the boards across buses can improve performance.
PAGE 9
NIC teaming support The NC7782 supports two types of teaming: Network Fault Tolerance (NFT) teaming and Load Balancing teaming. NFT teaming increases system availability by providing failover between a primary and a secondary network port on a server. It also monitors the server connection to the network and automatically switches traffic to a redundant link in the event of a failure.

memory for code, transfer buffers, and read/write cache.3 Optional SCSI cable assembly kit 365483-B21 is required for connecting a Smart Array Controller in a PCI slot to the internal hard drive backplane. Duplex configuration requires two such kits. Management technologies The ProLiant DL585 server is a highly reliable machine designed for efficient remote management and control. It ships standard with a full complement of HP management tools.
PAGE 11
Serviceability The DL585 has a blue Unit ID light on the front and rear panels to assist technicians in locating a specific server within a rack. A front panel LED displays internal and external server health information.
