Data Centers India | Dedicated Servers

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.

In order to regulate the functions of management and to minimize costs, companies and organizations seeking to optimize existing business processes on the relations parameters prices, performance, availability and scalability. This information becomes the most important asset, and its accessibility and relevance is a key factor for success in a competitive environment. Such a situation encourages the development of large-scale storage technologies which we get with data center services.

Modern data centers india services are providing secure storage of information resources, which also provide quick access to them. Such systems are based on disk arrays, infrastructure access, hardware and software for storage management (migration) of data and systems backup / archiving.

Network storage

Infrastructure access to storage devices is responsible for the rapid provision of information for applications and end users, so this subsystem is developing most rapidly: from the traditional direct connection of disk arrays to servers (DAS – Direct Attached Storage) to a rapidly spreading technology using the network as an access infrastructure to the data.

SAN (Storage Area Network) Technology  uses a dedicated network-based protocol Fibre Channel and makes the exchange of data at the block level. Devices NAS (Network Attached Storage), in fact, specialized file server, as transport involve the existing IP-based network, and operates at the file level. The best option is the use of SAN as a consolidated storage infrastructure, including NAS-devices, where the type of data access is determined based on specific requirements.
