Abstract This technology brief describes the architecture and the implementation of major technologies in HP ProLiant DL585 G5/G6 servers based on AMD Opteron® processors. These technologies include processors, memory, connections, power, management, and the latest serial input/output (I/O) technologies.

DL585 G5 processor architecture The DL585 G5 is a powerful, 4U enterprise server incorporating technologies that extend the capabilities of industry-standard x86 computing. This high performance server can run 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 AMD64 instruction set is a super-set containing the x86 instruction set architecture.

HyperTransport® technology. Direct Connect architecture is the AMD designation for the coherent HyperTransport connection between processors. It eliminates the bottlenecks inherent in front-side bus technology by integrating the memory controller into the processor and directly connecting CPUs to the I/O subsystem and other processors. HyperTransport is a parallel, point-to-point interconnect that replaces parallel front-side bus technology.

cache and reduces coherence traffic overload on the HT links, resulting in faster queries in both cache- and compute-intensive applications. AMD Dual Dynamic Power Management™ AMD Opteron processors feature AMD Dual Dynamic Power Management. This feature powers the processor core and memory controller voltage planes independently and delivers increased performance and improved power management.

Figure 3. Processor installation tool NVIDIA NForce Professional 2200 and 2050 chipsets The ProLiant DL585 makes use of both the NVIDIA nForce Professional 2200 and 2050 chipsets to offer a large number of expansion slots for enhanced flexibility. The 2050 chipset connects to the AMD-8132 HyperTransport tunnel with a 16-bit, 1-GHz HyperTransport interface. It provides 20 lanes of PCIe support divided into three x4 slots and one x8 slot.

Figure 4. Block diagram of DL585 G5/G6 architecture Memory technologies Typical multiprocessor PC server architecture connects IA-32 processors to memory DIMMs by means of a north bridge chip, which provides the memory controller function. However, in AMD Opteron architecture, the memory controller is integrated into the processor chip for enhanced performance. The on-die memory controller reduces memory latency by eliminating the bus contention between memory and I/O cycles on a typical north bridge.

will clock down in order to compensate for the additional load. Table 1 lists available memory configurations for the DL585. Table 1. Memory configuration options in the DL585 G5 & G6 DIMMs per processor Maximum memory speed 2, 4 800 MHz 6 667 MHz 8 533 MHz I/O technologies The DL585 supports two types of I/O expansion slots: PCI-X and PCI Express. The server includes two 64-bit, 100-MHz, PCI-X slots (one full-length, one half-length) that provide a 64-bit, 100-MHz interface for expansion devices.

Some configurations of the DL585 G5 include a battery-backed write cache (BBWC) on the P400 controller.

Smart Array P410 controller The DL585 G6 includes the Smart Array P410 controller. The HP Smart Array P410 is the HP PCI Express 2.0 (PCIe) Serial Attached SCSI RAID controller. The low profile, half height card has 8 ports and utilizes DDR2-800 memory. The P410 is ideal for RAID 0/1, 1+0, and 5+0. It can be upgraded with the 512MB BBWC module and Smart Array Advanced through the license key for RAID 6 and 6 +0. The P410 supports up to 12 drives and up to 2TB of total storage (6 x 500GB HDD).

available offline. The user must boot to the Smart Start CD and run ACU from there. Typically this feature is used when testing out a software patch. The user could split the mirror as a means to save the current data and then perform any type of destructive software update necessary, keeping the resulting data set or reverting back to the old data. BBWC is not required for this feature to be enabled. Capacity expansion is the process of adding physical drives to the array that has already been configured.
PAGE 12
Networking technologies The DL585 includes two BC5706i multifunction gigabit Ethernet (GbE) network adapters. Technologies supported by the BC5706i include TCP Offload Engine, Receive Side Scaling (RSS), and accelerated iSCSI. TCP Offload Engine Network bandwidth has improved steadily since the early days of TCP/IP networking. Along with this improvement in speed has come increased demand for CPU cycles to manage the network protocol stack.
