Generally would affect the performance of the database operator, all guests at the same time perform resource-intensive tasks. Another drawback is that an impairment of the performance of a machine within a virtual platform also affected all other machines at same database operator. There are three key points, which are easily overlooked: I/O bottlenecks and -operation, a file to dismember and produced in widely scattered areas on the disk to write performance discount on virtual platforms by accelerating fragmentation. Virtual disks that are aligned on dynamic growth, not shrink when data is removed. Instead, they waste space. Virtual machines compete for shared I/O Resources and their use is not effectively prioritized on the platform. These obstacles would open a weaker performance of virtual machines and would be offsetting the whole purpose of the migration to a virtual platform again. The solution consists in the optimization of systems without loss of resources.

Removing the fragmentation of the file-system level would have generated less I/O to the result and would mean unnecessary surplus/divisions of I/O sent to the disk system. Less I/O requests lead to better standards of I/O performance and reliability. One of the key areas of every good Virtualisierungsprojekts is the performance optimization. Some tend to focus your optimization efforts on the CPU and data storage, but forget the effects that can have virtual machines and data fragmentation on a virtual environment. Defragmentisierung can help considerably if there are problems with the disk latency, and it may be many with the consolidation of Related problems and bottlenecks facilitate disk-I/O channels.” David Marshall, VMblog.com (vmblog.com) hard disk space is a precious resource and each space wasted in a virtual environment is absolutely unacceptable.

Continuous monitoring of the used space, especially in a dynamic environment, is necessary and each place within the content is not used must be returned to the available data base, to other machines that need it to be able to be used. Better performance as well as better space utilization are elements of the efficiency promised through virtualization. An increase of in efficiency in these areas can lead to a realization of this promise which far exceed expectations.
