When emerged in the corporate world, data centers seemed to be ahead of its time. In the mid-90s, the idea of building large data centers was discredited. Research institutes indicated the implementation of powerful data warehouses with huge processing and storage volumes stratospheric as the new way forward. Theories aside, there were few limited projects. And most investment stopped in the middle. Although there was no technology infrastructure capable of supporting the wonders mentioned in market forecasts. It was not the time.

A decade later, the scene went back there designed to make perfect sense. And saw the data centers grow, mature and establish themselves globally. The impetus for the advancement of telecommunications say that technologies like internet, mobile, mobility and the companies won the fear of outsourcing.

Whatever segment of the company’s operations, partially or completely outsource the technology infrastructure. Few still cling to initial concerns about the quality of service and security of information, a result of services have become more professional, more comprehensive and complete. Fell business risks and costs. Rose, and much demands.

At the top of the wave, now the data centers remain highlighted. And with renewed amid a broad market expansion within and outside UK. Just look at some technologies that Gartner recently listed as the most influential segment: storage virtualization, cloud host, new server architectures, virtualization of PCs, enterprise mashups, hardware devices, software and social networks, unified communications and green IT.

And the current situation indicates more movement in the panel. New trends show that the proposal to centralize data can give rise to a hybrid model, where the great will to live with smaller structures, modular, decentralized. They come with enticing promises on issues such as lower power consumption and greater flexibility in updates.

Virtualization is one of the demands clearer today. With the prospect of strong demand for technology increases the supply of higher value-added services that help companies create and better manage their projects. Consolidation, optimization, management of high availability, redundancy requirements are in strong demand.

When the cloud host gain more muscles, it will be another major driver of data centers. In two or three years, with the concept that is more mature in the equation supply and demand, more resources will come. Interlinked projects on open platforms for software and social networks, and corporate trends like the use of mashups in business, call attention to a host of applications based on data center infrastructure. In short, long list of features and long life of service awaiting data centers.

green data center Geographically Located, Redundant Data Centers (Part III)Hi-protocol Fibre Channel, which is the basis SAN, you can send blocks of data at speeds up to 4 Gbit / sec. at distances up to 100 km. These characteristics allow you for synchronous data replication to a backup data center.

The valid period of recovery efficiency of IP also determines which of the regimes – a hot standby (hot standby) or as a gradual recovery (gradual recovery) – must operate redundant data centers. Hot backup mode means that the computational power back-up center is ready for action at any time. In this case, the transfer of operations to the backup power can be produced automatically. To use cluster technology, combining server systems primary and backup data centers into a single cluster complex with remote sites.

In addition to duplication of functions, the backup center could be used for partial discharge of computing a set of core data center. In this case, data centers will carry out mutual redundancy, and their resources are used optimally. In addition, backup data center can be used as a test site for training and testing software and hardware, planned for implementation.

Carrying out activities to create redundant data centers, it is necessary in parallel to solve organizational problems involving a number of operational measures for the detection and neutralization of emergencies. Emergency action plan (disaster recovery plan) to transfer information services at a power back-up center and disaster recovery data center core must be formed and perfected in advance. Similar activities should be conducted in case of an emergency at a secondary site.

During the recovery planning, conduct which would be in an accident on the main floor, includes the following:

  • Identification of critical functions of the ground data centers
  • Prioritizing rehabilitation
  • Strategy of rehabilitation
  • Verification of the strategy

In order to avoid repeated failures in the future, after elimination of the consequences arising from accidents is necessary to develop a set of measures to analyze the causes of the incident and assess the effectiveness of reconstruction.

Redundant data centers offer solutions that minimizes the risks in the event of various emergencies caused by natural disasters, intentional destruction or distortion of data, errors applied systems, inappropriate actions by service personnel, etc.
