What is different between the DL785 G5 and the DL785 G6?
A1.
The DL785 G6 adds 6 core AMD Opteron processors, updates the power supply units and provides support for new Smart array options and SAS expander card option as well . It also supports enhanced power management functionality to reduce energy cost and reclaim trapped capacity.
Q2.
Can I upgrade HP ProLiant DL785 G5 server with six-core AMD Opteron 8400 series processors
A2.
Yes, Now you can upgrade your HP ProLiant DL785 G5 Server with the six-core AMD Opteron 8400 series processors kit available with HP ProLiant DL785 G6 Servers. You will need to upgrade to the latest version DL785 G6 firmware and following the "Processor Option Installation Instructions" that comes with processor kit.
Choose the processor kit that suits your business needs:
What is new about the Opteron 8400 Series processors?
A3.
In addition to supporting all 8300-series features, the 8400 series adds additional enhancements. These include:
-AMD CoreSelect™, allowing customers to select the number of software-visible cores per CPU. This can provide additional performance and price/performance benefits depending on workload. -HT Assist™, which works to reduce coherence traffic overload on the HT links. This can result in faster queries in both cache- and compute-intensive applications.
Q4.
What quantity processor configurations are supported on the DL785 G6?
A4.
The DL785 G6 will support increments of 4 and 8 processors only.
Q5.
What are the rules for populating DIMMs?
A5.
DIMMS must be installed in pairs, in addition:
-DIMMs installed in 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 capacity with the largest DIMMs installed in the banks furthest away from the processor -A minimum of two DIMMs (1 kit) must be installed per processor
Q6.
What is AMD CoreSelect™? How does it benefit the end user?
A6.
AMD CoreSelect allows a user to select a number of cores to be enabled per CPU (minimum one, up to full number supported). It can improve performance of applications not written to make use of the full number of CPU cores in the system. Gives them access to more cache and greater memory bandwidth per thread.
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 is Dynamic mode of Power Regulator for ProLiant?
A9.
Power Regulator is an innovative power management feature of HP ProLiant servers that offers alternatives to manage server power consumption and system performance to meet critical business needs. 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.
Q10.
Which Power Management functionalities are supported on DL785 G6?
A10.
Power monitoring, Power regulation and Power capping functionalities are supported on HP ProLiant Dl785 G6. These enhanced power management functionalities available through iLO and HP Insight Power Manager.
Q11.
What is Dual Dynamic Power Management?
A11.
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 DL785 G5 as well, uses a "split" power plane in the motherboard in order to deliver different voltages to different parts of the processor.
Q12.
What services do we recommended for DL785 G6 servers?
A12.
HP Services portfolio is well equipped to address a broad spectrum of customer needs, from reactive hardware and software support, to proactive mission critical service offerings that help customers plan, design, transition, operate and continually improve their infrastructure. For customers running their DL785 G6 systems to support critical business workloads we recommend HP's Proactive and Mission critical services to assist customers deliver business value through a reliable, stable and performance optimized infrastructure capable of rapidly coping to changing business needs.
Q13.
Are standard foundation HP Care Pack support services available for this product?
A13.
Yes both installation and start up deployment services and full portfolio of warranty upgrade offers are available for each grouping. 13×5 and 24×7 4 hour response plus 24x7 6 hour call to repair with 3,4 and 5 year coverage options available. In addition the option to include defective media retentions within service is available in America's and APJ.
Q14.
Will the DL785 G6 include or have the option for a pedestal kit?
A14.
No, the DL785 G6 is available as a racked server only.
