HP ProLiant DL585 G5 Server series - questions & answers

Questions

Answers

In order to better communicate the similar sets of features and options available to concurrent ProLiant products, HP has aligned the generation designator (G5) for the DL585 to match other servers that are currently available. There is no DL585 G3 or DL585 G4 generation.

• Independent Dynamic Core Technology, which generates power savings from independent control of frequency per core;
• AMD CoolCore^TM Technology, which yields power savings through coarse & fine transistor control inside the processor;
• Dual Dynamic Power Mangement ^TM, which yields power savings and/or increased performance by providing independent voltage planes for cores and memory controllers;
• AMD Wide Floating Point Accelerator, which provides increased floating point performance though a 128-bit floating-point pipeline;
• Rapid Virtualization Indexing, increasing virtualization performance though Nested Page Tables and Tagged TLBs

• Processor models 8384, 8382, 8380, and 8378 can support either PC2-6400 (800MHz) or PC2-5300 (667MHz) memory modules. If PC2-6400 memory modules are used with any other supported CPU, the maximum frequency of the memory will be 667MHz.
• DIMMs installed on the same memory bank must have the same part number.
• DIMMs installed in different banks can be different sizes.
• DIMMs must be installed in decreasing capability with the largest DIMMs installed in the banks furthest away from each processor.
• DIMM banks are only active when the corresponding processor socket is populated.

Average CPU Power (ACP) is a new metric designed by AMD to give customers a more accurate idea of the power consumed by the processor, allowing customers to more realistically forecast their power budget assessments to estimate how much power might actually be consumed at the wall and more accurately allow them to plan their data center power and cooling infrastructure. ACP measurements were taken on specially instrumented internal engineering server platforms. Thermal Design Power (TDP), is used to represent the maximum power for the processor.

Power Regulator enables dynamic or static changes in CPU performance and power states. In dynamic mode, it automatically adjusts server processor power usage and performance to match CPU application activity. This improves energy efficiency by giving CPUs full power for applications when they need it and enabling power savings without performance degradation when application activity is reduced. Power Regulator executes automated policy-based power management at the individual server level. In addition, a unique static low power mode allows servers to run continuously in a system's lowest power state.

Power Regulator is an innovative operating system-independent power management feature of HP ProLiant servers that offers alternatives to manage server power consumption and system performance to meet critical business needs.

This power management technology enables dynamic or static changes in CPU performance and power states. In dynamic mode, Power Regulator automatically adjusts the server's processor power usage and performance to match CPU application activity. This improves server energy efficiency by giving CPUs full power for applications when they need it and enabling power savings without performance degradation when application activity is reduced. Power Regulator effectively executes automated policy-based power management at the individual server level. In addition, a unique static low power mode allows servers to run continuously in a system's lowest power state.

In addition to Power Regulator, ProLiant servers also support operating system based power management using AMD Opteron's PowerNow!. A driver is required to use operating system based power management.
