Data virtualisation is key for the data centre of the future

The average power density per rack will increase significantly in the coming years, creating new challenges in thermal management, a recent study by Emerson Network Power has revealed.

The study, which interviewed 800 global data centre specialists about the centre of the future, examined expectations of how power requirements would evolve between now and 2025. The results highlighted improvements in energy efficiency as a big issue for almost two thirds of respondents, with many expecting that data centres will leverage emerging technologies to consume significantly less energy over the next ten years while providing the same computing power.

According to the Emerson Network Power study, there is a lack of "transparency over the different systems". In many data centres, "silo-like structures" still prevail because individual systems communicate with different protocols. The big challenge is to "develop solutions that collect data across all systems, and translate them, so that one management solution can work with it." Data virtualisation makes it possible already today to control access to application data centrally, so automatically there is better transparency for data management.

Silo structures have much to do with the traditional approach of data management, where copies of the same data are held for different purposes: analysis, backup, development, testing, disaster recovery etc.

These data silos can be replaced by a central Copy Data Management platform. Data will then be recorded directly from within applications, centrally stored, managed and globally de-duplicated. A master ‘golden’ copy is created and saved. Changed blocks are always stored incrementally, so the master copy is always up to date. Whenever required, this master copy can generate countless virtual copies for any purpose. Fewer memory resources are used, since there is only storage space required for one physical master copy. Virtual data copies are available at any time - even faster than in conventional memory variants.
