What is different between the DL585 G2 and the DL585 G5?
A1.
The DL585 G5 adds quad-core AMD Opteron processors, plus support for Dual Dynamic Power Management, to the award-winning feature set of the DL585 G2. In addition, new ROM and firmware based management features (such as Dynamic Mode of Power Regulator for ProLiant) are included. The I/O subsystem (including chipset, I/O slots, and power supplies) remain consistent with the DL585 G2.
Q2.
Is there a DL585 G3 or DL585 G4?
A2.
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.
Q3.
What is new about the Opteron 8300 Series processors?
A3.
The AMD Opteron 8300 series of processors introduce native quad-core to the Operton family. Other features of the 8300 series of processors include:
- Independent Dynamic Core Technology, which generates power savings from independent control of frequency per core - AMD CoolCore™ Technology, which yields power savings through coarse & fine transistor control inside the processor; - Dual Dynamic Power Management™, 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
Q4.
What are the rules for populating DIMMs?
A4.
DIMMs must be installed in pairs. In addition:
- 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.
Q5.
What is Dual Dynamic Power Management?
A5.
Dual Dynamic Power Management™ is a feature that yields power savings and/or increased performance by providing independent voltage planes for cores and memory controllers. The feature, which is supported in the DL585 G5, uses a "split" power plane in the motherboard in order to deliver different voltages to different parts of the processor.
Q6.
Does the DL585 G5 support dual- or single-core processors?
A6.
No. The Opteron 8300 series does not include dual- or single-core processors.
Q7.
What is Average CPU Power (ACP)?
A7.
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.

Q8.
Do I need a driver to utilize AMD PowerNow! technology?
A8.
AMD PowerNow! is a technology within some AMD processors that enables enhanced power management by offering multiple processor power states. HP offers multiple ways to enable PowerNow!, including the BIOS-controlled Dynamic mode of Power Regulator for ProLiant, which does not require an OS driver.

Q9.
What benchmarks are available that show the performance of the DL585 G5?
A9.
ProLiant DL585 G5 benchmarks are available on the ProLiant benchmark website and Opteron specific benchmarks can be found on AMD's website.
Q10.
What service offerings are recommended?
A10.
A full range of hardware and software support offerings are available ranging from installation services to 7/24 on-site repair coverage. HP recommends 4 hour same day response and software technical support to maximize uptime, improve system performance, and increase the productivity of system managers/operators.
