The goal of the project is to organize a fault-tolerant network infrastructure.

A public sector client in the Asian region is modernizing its corporate IT infrastructure. The new architecture should be geographically distributed in two different data centers, each of which will perform its function – the main one, regularly serving users, and the backup one, which provides fault tolerance. One of the key requirements for the architecture was the ability to provide L2 connectivity between data centers. In addition, the corporate network of the customer includes more than 100 geographically distributed offices, with each of which communication must be continuously maintained. The key is the reliable and uninterrupted operation of the company's server infrastructure. Designed and proposed solutions based on Hewlett-Packard Enterprise (HPE) equipment. HPE works successfully in the international IT market and specializes in the design and production of telecommunications equipment, servers and enterprise-class data storage systems.

Fields of application or industries for which this solution is suitable

  • A large enterprise-level company
  • Any other company that needs a fault-tolerant and reliable network perimeter

Tasks for the executor of the project

The choice of solution architecture is based on the following requirements of the customer:

  • High performance of the corporate data transmission network
  • High level of information security
  • Reliability and round-the-clock availability of network services
  • Convenience and simplicity of administration and operation
  • The need for continuous connectivity between two geographically distributed data centers


The core of the network in each data center is an HPE 7900 switch. At the access level, HPE 5900 switches are used for 1/10G server connections. At the perimeter of the network, HPE HSR 6602 routers are used. For security, two HPE TippingPoint S3020F gateways are used, managed by an HP vSMS server. To ensure connectivity between data centers, the EVI protocol is used based on HPE 7900 switches. ADVPN and the OSPF protocol are used for routing and security between data centers and remote sites, and HPE MSR 1008 routers are used at remote sites. A system was implemented to monitor and manage the network infrastructure HPE IMC.
