HP Integrity iLO 3
Integrity server blades include the Integrity iLO 3 management processor. Each individual blade in conjoined server
blades contains a physical iLO 3, but the management is aggregated into a single unified iLO 3 user interface. The c-Class
enclosure includes an Ethernet management network to aggregate all iLO 3 management communications across the
entire enclosure. This management network connects iLO 3 processors to the BladeSystem OA through the BladeSystem
OA tray. The BladeSystem OA provides direct access to each iLO 3 through the enclosure management network. The
BladeSystem OA uses this network to manage pooled enclosure power and cooling. In addition, every Integrity server
blade ships with an Integrity iLO 3 Advanced license key factory installed. This key enables advanced management
features of the iLO 3 such as virtual media and integration with Insight power management.
HP Insight Control for HP-UX
Insight Control for Integrity provides centralized management tools for deployment, performance analysis, power
management, and health monitoring. Full Insight Control functionality is included in the HP-UX 11i v3 Operating
Environments. Applications such as Software Assistant (SWA), Systems Management Homepage (SMH), and Insight Control
power management (ICpm) can be run from the Systems Insight Manager (SIM) consistent multi-system management and
provide an agile and resilient foundation to meet service levels continuously in an Adaptive Infrastructure.
• HP SIM provides a single tool for managing HP Integrity, ProLiant, and HP 9000 systems.
• HP SMH is a Web-based interface that consolidates and simplifies single system management for HP servers.
• SWA simplifies patch and security bulletin management on HP-UX systems.
• Ignite-UX is an HP-UX administration toolset that allows simultaneous installation of HP-UX on multiple clients,
creation of golden images and recovery media.
• Insight Control power management provides graphical power and thermal monitoring, power event response, and
intelligent discovery of power topology.
Details on Insight Control for OpenVMS and Windows

are expected to be provided when those OS platforms are
qualified on the HP Integrity server blades.
Power management technologies
Power meter
An integrated power meter in HP c-Class server blades analyzes actual server power use. The BladeSystem OA can
access the power meter through the Integrity iLO 3 and can communicate through external power management
software such as Insight Control power management. Insight Control power management also consolidates power
data for multiple servers to a central location. IT departments can use this information to charge business units or
third parties for the actual energy costs associated with workload processing. The BladeSystem OA provides instant
and time-averaged views of the power consumption of individual servers or of all servers within a c-Class
BladeSystem enclosure.
OS power regulation
HP-UX 11i v3 can realize a power savings of processor power on a system with the pwr_idle_ctl command, which
determines how aggressive the OS will be in keeping a processor idle once it has become idle. Some states have been
optimized to save power with practically no performance penalty. Active processors have power saving options with the
pstatectl command. Active processors can be set to a dynamic control mode that can change performance states to
match processor performance (and power consumption) with utilization requirements. A static control mode is also
available which allows a processor’s performance state to be set and maintained at a tunable value.
HP Dynamic Power Capping
Dynamic Power Capping can bring a server experiencing a sudden increase in workload back under its power cap in less
than one-half second. This fast response prevents any surge in power demand that could cause a typical data center
circuit breaker to trip. Dynamic Power Capping prevents tripping circuit breakers that have a specified trip time of three
seconds or longer at 50°C and 150 percent overload.
