Introduction

New chassis/rack architecture

The new line of HP ProLiant SL6500 Scalable Server, HP ProLiant DL1000/DL2000 Multi-Node Server,

and HP ProLiant SL6000 Scalable Servers implement entirely new chassis/ rack architecture in the

industry standard server market space, producing the most power efficient and power manageable

servers in the world. Each 2U chassis consists of up to 4 nodes, up to 24 HDDs, and up to 4 fans. Each

4U chassis consists of up to 8 nodes, up to 16 HDDs, and up to 8 fans. Each chassis also contains an

embedded microcontroller that provides power metering and throttling capabilities for the entire chassis.

Power Interface Controller

As depicted in the above diagram, the embedded Power Interface Controller is able to monitor power

consumption for all aspects of the 2U/4U chassis and throttle the speed of the processors and memory in

each node within the 2U/4U chassis in order to maintain a pre-set power budget.

Power Control Configuration 5

Power Control Configuration

Power Interface Control modes

Mode Configuration

0 No Redundancy, Power throttling disabled.

1 AC Redundancy with throttling- This provides Maximum Performance with PS Redundancy. Power

control logic will only throttle the performance of each node in the case where the chassis only

has one operational power-supply. In this mode, the box is expected to survive an unexpected

AC Power loss to one of the power supplies. (This is the default.)

2 Full AC/DC Redundancy- Power control logicl maintains a power cap value at the DC rating of a

single power supply (Example: 460W, 750W, or 1200W), such that if one power supply

experiences a DC or AC failure, the chassis remains on-line and operational. User must be

cognizant of the minimum power consumption of the chassis and this must be less than the rating

of a single power supply. Running the PPIC utility with the -c option provides this information.

3 User Configurable- User specifies the power envelope for the chassis, within the capabilities of

the HW installed. Before setting this mode, it is required that the user run the PPIC utility with the -

c option in order to calibrate the minimum and maximum power consumption envelope for the

chassis. For accuracy,run the -c command after installing and configuring all HW, and bringing

all nodes on-line in the chassis. In order to avoid punitive performance due to throttling,do not set

a User configurable power cap limit value below or within 20% of the minimum power value

provided by the PPIC -c option.

Note: The User Configurable power capping mode is included with the LO100/iLO 3 Advanced

Pack.

Supported OSs 6

Supported OSs

OS utility versions

Versions of this utility are available for Microsoft Windows Server OS (2008 and 2008 R2) and Linux OS

(RHEL5 and SLES11) with the requirement that the OS IPMI Driver be installed.

PPIC Utility and Usage 7

PPIC Utility and Usage

Command line utility

HP provides a simple command line utility, called PPIC, for reading and configuring the power control

logic of the SL product lines. Running the PPIC utility from the command line without any command-line

options provides a dump if the usage as shown below.

The PPIC utility must only be executed through one server node per chassis.

HP ProLiant Power Interface Configuration Utility v.1.2.0.0
