Huawei DC²: Next Generation Innovative Data Center Architecture in Cloud Era

Gaia is a living organism that contains all the lifeforms and other non-living material in the galaxy, every piece of information is stored in its collective consciousness.


Galactic Empire by Isaac Asimov


Great science fiction writers are like prophets. They help readers cross the threshold of time and advance towards the future of the world. Verne's description of a moon landing a century ago was strikingly consistent with the later manifestation thereof, while Asimov's Three Laws of Robotics later became regarded as the golden rules for the entire field of robotics. As humanity's technological capabilities continue to develop, prophecy will become a reality.


Difficulties and Challenges of Data Center Carriers

The rapid development of ultra-wideband network, the emergence of software defined networking (SDN) technology, and the development of multiple technologies involved in cloud computing over more than a decade have all promoted a new round of changes in the data center. All data center carriers (carriers for short) have encountered the following challenges:


  • Grasp the opportunity to lead change, take advantage of existing systems, and introduce new architectures to meet the industry's demand.
  • Resolve the problems, such as high investment risk, long construction periods, high energy consumption, low resource utilization, system isolation, slow service response, and high operating expense (OPEX), caused by intensive construction of traditional data centers.


Technologies and other features of a traditional data center vary according to different construction stages. For example, there is a global carrier that has constructed over 85 data centers (equipment rooms) of different sizes in more than 20 years based on the technical capabilities and business demands in different development stages. This global carrier has more than 5,000 servers of different specifications, supporting over 4,000 types of applications and more than 10 types of heterogeneous databases. Diverse and heterogeneous IT data centers support the business and development of this global carrier, but also bring great management, upgrade, maintenance, and operating costs, and delay subsequent developments. This global carrier has to spend huge amounts of human resources to maintain the existing large-scale data centers and overall businesses, while at the same time carefully exploring new frameworks.


Science fiction masters foresee the future with their forward-looking visions, while technology masters respond: "The best way to predict the future is to create it." Gaia integrates all types of separated systems into a complete and unified wisdom. Similarly, with the support of new technologies, Huawei is able to integrate carriers' micro-, medium-, and macro-data centers across the globe into a physically dispersed but logically unified intelligent data center called Distributed Cloud Data Center (DC²). The DC² can make full use of carriers' capabilities to support long-term future development.


New-Generation Data Center in Cloud Era— DC²

The DC² end-to-end solution changes the traditional model of data centers, with scattered, hierarchical, and heterogeneous architectures, into distributed cloud data centers with a flat architecture, point-to-point interconnection, and unified resource management. The DC² solution virtualizes data centers in different regions, stages, and scales into a logical resource pool that incorporates physical and virtual resources. This allows carriers to achieve unified management, presentation, and operation.



Huawei DC² fulfills enterprise data center transformation with 2 key technologies bellowing:




Huawei FusionSphere is based on OpenStack and extends features required by carriers to construct their IT facilities and service platforms. Huawei FusionSphere can support third-party computing, storage, network, and security devices (including physical devices and virtualized products). In addition, Huawei FusionSphere provides extended services, such as backup, hot migration, resource scheduling between data centers, cloud customized extension, elastic service scheduling, smart pipe scheduling, distributed engines, and physical resource pools. Huawei FusionSphere is compatible with the OpenStack cloud bus, which helps resolve vendor lock-in problem and changes the construction mode of data centers.


  • Huawei ManageOne unified O&M management support platform compatible with heterogeneous systems


The ManageOne promotes easy management, agile operation, and energy conservation. The ManageOne realizes comprehensive management during the resource life cycle, including unified maintenance, unified management of cloud and non-cloud resources, automatic discovery and configuration, resource allocation and reclaiming, service application deployment, flexible product defining, and rapid service rollout.


DC²Facilities

The development of efficient modular data center technologies makes it possible to construct data centers that are physically distributed but logically integrated. The new-generation data center facilities must be integrated, efficient, and flexible. The Huawei DC² data center facility solution (CloudPower) adheres to the efficient modular construction concept by providing five subsolutions that flexibly combine basic components, including the cabinet, confined channel, refrigeration, power supply, and distribution components. CloudPower not only satisfies construction requirements for outdoor rapid deployment and mobile applications, but is also appropriate for micro, small, medium, and large data center service scenarios. The five subsolutions are distinctive and highly complementary, and fully meet the facility requirements of the DC² data center.


Benefits

Uses management efficiency as a core concept, improving ROI


  • Compatible with heterogeneous systems, supports unified management for physical and virtual resources, and makes full use of DC resources to reduce investments.
  • Supports seamless expansion, with up to millions of physical nodes.
  • Pools DC resources, thereby maximizing management efficiency and minimizing manual intervention.


Provides user-centric services, ensuring SLA


  • Focuses on user experience. For example, roaming users can enjoy excellent services when using applications.
  • Integrates service automation with the intelligent network channel to ensure the quality of service (QoS) and provide stable services.
  • Uses the hot and cold data separation deployment mode and DR system to ensure the reliability and sustainability of the DC².


Uses optimal resource scheduling and deployment as a target, reducing TCO


  • Integrates dispersed computing, storage, and network physical and virtual resources to construct a unified and logical cloud resource pool, thereby maximizing resource reuse rates.
  • Implements proper service deployment, sends intelligent and unified resource requests, and performs SDN scheduling across DC nodes, thereby achieving the maximum energy efficiency ratio (EER).
  • Supports multiple flexible and efficient resource management modes, including direct service release modes (such as the hosting mode) and indirect service modes (such as the VDC and PDC).


Conclusion: unification after prolonged division

There are high requirements for DCs due to new economic and environmental constraints on services. The goal of the Huawei new-generation DC² is to consolidate traditional DCs, introduce innovative technologies, maintain existing services, and exploit new opportunities. The Huawei DC² comes at a transformative moment for carriers' DC services and aspires to be part of this transformation.
