Huawei Reckons It Can Build You A New Data Center In Half The Usual Time

­­Enterprises usually build multiple information centers to ensure Disaster Recovery (DR). The active data heart transmits users’ core services. Backup data centers transmit some not-primal services, and backup data, configurations, and services of the active information eye. The active data center and the fill-in data centers piece of work independently. If a disaster occurs and the agile data center cannot provide its core services, then the backup data centers tin can quickly recover data and applications. This reduces any losses caused by the disaster.

A Data Center Interconnect (DCI) network plays a disquisitional role past transmitting services with one of three interconnection methods: Layer i optical transmission interconnection, Layer two interconnection, and Layer 3 IP interconnection. Different services accept different interconnection requirements. Hierarchical interconnection and disaster recovery create data centers that feature High Availability (HA) interconnection and service continuity. In add-on, server clusters can be installed in unlike information centers to enable disaster recovery for application systems.

Data-level and service-level disaster recovery take different requirements. For example, storage networks  require low latency, large bandwidth, and loftier reliability, and service networks require link backup and fast route convergence.

Layer 1 interconnection:

Features low latency, big bandwidth, high security, and reliability to provide real-time data centre disaster recovery

The rapid development of deject calculating and Big Data requires that enterprises provide ‘uninterrupted services’ and ‘no information loss.’ To exercise this, data centers

must provide real-time backup mode to ensure data synchronization between the storage systems of active and backup information centers. This ensures that customers will non experience any latency in service processing speed and that data is not lost.

Layer 2 interconnection:

  • Signaling:
    For HA clusters in different sites, the states of cluster nodes are maintained and controlled through heartbeat signaling and data synchronization.
  • Cross-site VM migration:
    Virtualization technology is becoming increasingly important for disaster prevention. Virtual Motorcar (VM) migration plays an important role in the expansion of information heart capacity. Information center services transmitted by VMs must non be interrupted during VM migration. Land synchronization and maintenance sessions require that physical servers be located in the same subnet prior to and subsequently VM migration. Therefore, cross-site VM migration
    also requires Layer 2 network interconnection.
  • Problems:
    Still, at that place still are problems that must be solved; Poor adaptability does not allow Ethernet technology expansion based on different networks; just a limited number of information eye interconnections are possible; Flooding of unknown IP address traffic and suboptimal paths causes a considerable waste of WAN link bandwidth; Multi-homing admission is non available. Traffic forwarding does non enable load balancing; Network configurations are tedious, and Operations and Maintenance (O&M) is complex.

    Layer three interconnection:

  • Layer iii admission networks interconnect by means of IP technnology
  • Internal and external users admission data center services through a Layer 3 gateway on a campus network or Wide Area Network (WAN)
  • Layer three service access among unlike data centers includes active and disaster recovery centers. If a disaster occurs in the active data center, the Layer iii disaster recovery network quickly takes over services of the afflicted information center, ensuring that customers are continuously provided with all data center services.
  • Preventing risks:

    Preventing disruption of services caused past a single information centre disaster has go the focus of enterprise users. Data centers require high levels of protection against risks that include loftier volumes of information aggregation and natural disasters such equally storms and earthquakes. Data center disaster recovery is divided into data heart, service-, and application-level disaster recovery. Specific disaster recovery mechanisms can exist selected based on users’ investment and service growth demands.

    Optical Transport Network (OTN) Interconnection

    Huawei CloudFabric uses a large-capacity, depression-latency optical transmission interconnection solution to provide Fibre Channel Storage Area Network (FC SAN) and Internet Protocol Storage Area Network (IP SAN) arrangement interconnection and disaster recovery.

    Huawei Optical Switch Node (OSN) serial OTN devices provide manufacture-leading WAN transmission capabilities. These devices tin form loftier-speed, existent-time Wavelength Partition Multiplexing (WDM) optical networks. They also tin can exist used by disaster recovery systems that require large capacity and low manual latency, and can transmit massive amounts of data. For example, a single cobweb provides upwardly to 8 Tbit/s bandwidth. OSN series devices support xiv types of SAN interfaces (such as FC, FICON, and ESCON) and have earned compatibility certificates from seven mainstream storage device vendors. OSN series devices can establish a SAN that enables the longest disaster recovery distance in the industry (3,000 km). They also provide carrier-grade (50 ms) protection switching.

  • Disquisitional DR Indicators

    The 2 almost critical indicators for measuring disaster recovery are Recovery Time Objective (RTO) and Recovery Signal Objective (RPO). The ultimate goal of all disaster recovery solutions is for the value of these ii indicators to exist as close to zero as possible.

    RTO indicates the time from when services are interrupted due to an IT organization breakdown to the time when the IT arrangement recovers and can support operations of all departments. RPO indicates a recovery indicate at which both system and awarding data can be recovered to support service operations of the entire department. The extent to which the system and application data are recovered can be the final week’southward backup information or real-fourth dimension data of the latest transaction.
