Because the enclosures are designed to include separate physical cooling zones, the Active Cool fans
provide cooling for their own zone and redundant cooling for the rest of the enclosure. One or more
fans can fail and still leave enough fans to adequately cool the enclosure.
To ensure scalability, HP designed both the fans and the power supplies with enough capacity to
meet the needs of compute, storage, and I/O components well into the future.
HP optimizes the cooling capacity across the entire enclosure by optimizing airflow and minimizing
leakage through the use of a relatively airtight central plenum, self-sealing louvers surrounding the
fans, and automatic shut-off doors surrounding the device bays.

Configuration and management technologies

One of the goals of the BladeSystem c-Class architecture was to dramatically reduce the amount of
time that IT personnel must spend to deploy and manage new systems. To achieve this design goal,
HP provided an intelligent infrastructure that makes essential power and cooling information available
to administrators and helps automate infrastructure management. Implementing the c-Class Onboard
Administrator is the result of these goals.
The BladeSystem c-Class architecture also reduces the complexities of switch management in a blade
environment. Blade environments provide distinct advantages because their direct backplane
connections between switches and blades reduce the number of cables, and therefore cost and
complexity. However, early generations of blade environments created the challenge of managing
many additional small switches. HP solved this in an innovative way by developing Virtual Connect
technology. Virtual Connect technology provides a way to virtualize the server I/O connections to
Ethernet or Fibre Channel networks.

Integrated Lights-out technology

Each ProLiant server blade designed for the BladeSystem c-Class includes an iLO 2 management
processor. The iLO 2 processor monitors thermal and operational conditions within each server blade
and forwards this information on to the Onboard Administrator. Regardless of a server blade's
operating condition, the iLO 2 management processor enables the remote management capabilities
that customers have come to expect from ProLiant servers: access to a remote console, virtual media
access, virtual power button, and system management information such as hardware health, event
logs, and configuration. The iLO 2 device provides a higher-performance remote console (virtual
KVM) as well as virtual media functionality that administrators can access from a web browser,
command line, or script. The virtual KVM uses an architecture that acquires video directly from the
video controller and uses an enhanced compression and refresh technology that reduces the amount
of traffic on the network (thereby improving network efficiency).

Onboard Administrator

Onboard Administrator is a management controller module that resides within the BladeSystem
c-Class enclosure. The Onboard Administrator controller communicates with the iLO 2 management
processors on each server blade to form the core of the management architecture for BladeSystem
c-Class. Customers have the option of installing a second Onboard Administrator board in the c7000
6 The number of fans that can fail depends upon the number of blades, the number of fans, and the location of
the blades. The OA reports thermal subsystem status and redundancy level, and will provide alerts when the
thermal subsystem status changes.
