  • Page 3: Abstract

    Abstract This technology brief describes the underlying architecture of the BladeSystem c-Class and how the architecture was designed as a general-purpose, flexible infrastructure. The HP BladeSystem c-Class consolidates power, cooling, connectivity, redundancy, and security into a modular, self-tuning system with intelligence built in. The brief describes how the BladeSystem c-Class architecture solves some major data center and server blade issues.

  • Page 4: Evaluating Requirements For Next-Generation Server And Storage Blades

    Evaluating requirements for next-generation server and storage blades More critically than ever, data center administrators need agile computing resources that they can use fully but can change and adapt as business needs change. Administrators need 24/7 availability and the ability to manage power and cooling costs, even as systems become more power hungry and facility costs rise.

  • Page 5: Component Overview

    An HP BladeSystem c-Class enclosure accommodates server blades, storage blades, I/O option blades, interconnect modules (switches and pass-thru modules), a NonStop passive signal midplane, a passive power backplane, power supplies, fans, and Onboard Administrator modules. The BladeSystem c-Class employs multiple signal paths and redundant hot-pluggable components to provide maximum uptime for components in the enclosure.

    The HP BladeSystem enclosures can accommodate half-height or full-height blades in single- or double-wide form factors. The HP website lists the available products: www.hp.com/go/bladesystem/. Optional mezzanine cards within the server blades provide network connectivity by means of the interconnect modules in the interconnect bays at the rear of the enclosure. The connections between server blades and a network fabric can be fully redundant.

    variety of memory technologies that give customers options when weighing memory capacity, power use, and cost. Interconnect form factors HP selected a single-wide/double-wide interconnect form factor to achieve efficient use of space and improved performance. A single interconnect bay can accommodate two smaller interconnect modules in a scale-out configuration or a larger, higher-bandwidth interconnect module for scale-up performance (Figure 5).

    modules. For example, within a given enclosure, all mezzanine cards in the mezzanine 1 connector of the server blades must support the same type of fabric. HP developed the electronic keying mechanism in Onboard Administrator to assist system administrators in recognizing and correcting potential fabric mismatch conditions as they configure each enclosure.

    For detailed information about the c-Class server blades, see the technology brief titled “HP ProLiant c-Class server blades,” available at http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01136096/c01136096.pdf. NonStop signal midplane scalability The NonStop signal midplane is capable of conducting extremely high signal rates of up to 10 Gb/s per lane (that is, per set of four differential transmit/receive traces).

  • Page 18: Power Backplane Scalability And Reliability

    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. Figure 12.

  • Page 19: Server Blades And Processors

    Server blades and processors At the processor level, HP Power Regulator for ProLiant is a ROM-based power management feature of HP ProLiant servers. Power Regulator technology takes advantage of the power states available on x86 processors to scale back the power to a processor when it is not needed. Because the c-Class architecture shares power among all server blades in an enclosure, administrators can use Power Regulator technology to balance power loads among the server blades.

  • Page 20: Dynamic Power Saver Mode

    Dynamic Power Saver Mode Most power supplies operate inefficiently when lightly loaded and more efficiently when heavily loaded. When enabled, Dynamic Power Savings mode will save power by running the required power supplies at a higher rate of utilization and putting unneeded power supplies in a standby mode.

  • Page 21: Configuration And Management Technologies

    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.
  • Page 22 enclosure to act as a redundant controller in an active-standby mode. In the future, HP plans to offer redundant Onboard Administrator capabilities for the c3000 enclosure. Onboard Administrator collects system parameters related to thermal and power status, system configuration, and managed network configuration. It manages these variables cohesively and intelligently so that IT personnel can configure the BladeSystem c-Class and manage it in a fraction of the time that other solutions require.

  • Page 23: Virtualized Network Infrastructure With Virtual Connect Technology

    Figure 13. The main menu on the Insight Display IT technicians and administrators can access the Onboard Administrator in any of three ways: through the Insight Display, through a web graphical user interface (GUI), or through a command-line interface (CLI). A fourth access method is available for the c3000 enclosure: The optional c3000 KVM Module provides the Onboard Administrator CLI, Insight Display, and KVM console connections to all the server blades in the enclosure.
  • Page 24 Figure 14. HP Virtual Connect technology provides server-edge virtualization From the perspective of the network and storage administrators, the LAN and SAN connections are established with the pool of servers, and the administrators see no changes to their networks. This allows moving workloads and adding or replacing servers without affecting the LAN or SAN.

  • Page 25: Availability Technologies

    Availability technologies The BladeSystem c-Class incorporates layers of availability to enable the 24/7 infrastructure needed in data centers. Using redundant configurations eliminates single points of failure, and the c-Class architecture reduces the risk of component failures and the time required for changes. Redundant configurations The BladeSystem c-Class minimizes the chances of a failure by providing redundant power supplies, fans, and interconnect modules.

  • Page 26: Reduced Logistical Delay Time

    Finally, Onboard Administrator’s thermal monitoring of the entire system ensures that the Active Cool fans deliver adequate cooling to the entire enclosure. Because the fan design uses a high-performance motor and impeller, it consumes less power and uses less airflow to cool an enclosure than a traditional fan design would.
