Power Backplane Scalability And Reliability; Power And Cooling Architecture With Hp Thermal Logic - Compaq BL10e - HP ProLiant - 512 MB RAM Configuration

Power backplane scalability and reliability

The power backplane is constructed of solid copper plates and integrated power delivery pins to
ensure power distribution with minimum losses (Figure 12). Using solid copper plates reduces voltage
drops, provides high current density, and high reliability.

Power and cooling architecture with HP Thermal Logic

Power conservation and efficient cooling were key design goals for the BladeSystem c-Class. To
achieve these goals, HP consolidated power and cooling resources, while efficiently sharing and
managing them within the enclosure. HP uses the term Thermal Logic to refer to the mechanical
features and control capabilities throughout the BladeSystem c-Class that enable IT administrators to
optimize their power and thermal environments.
Thermal Logic encompasses technologies at every level of the c-Class architecture: processors, server
blades, Active Cool fans, and the c-Class enclosure. Through the Onboard Administrator controller, IT
administrators can access real-time power and temperature data, allowing them to understand their
current power and cooling environments. Onboard Administrator allocates power to the device bays
based on the specific configuration of each blade in the enclosure. As blades are inserted into the
enclosure, the Onboard Administrator discovers each blade and allocates power accordingly, based
on actual measured power requirements.
Onboard Administrator also allows customers to dynamically and automatically adjust operating
conditions to meet their data center requirements. This allows them to maximize performance based
on their power and cooling budgets and to forestall expensive power and cooling upgrades.
The technology briefs titled "HP BladeSystem c-Class c7000 enclosure technologies" and "HP
BladeSystem c-Class c3000 enclosure technologies" give additional information about HP Thermal
Logic technologies. Both are available on the HP technology website at
