Virtualization Essentials

Tuning Practices for VM Storage

As mentioned earlier, storage is one area where performance issues often arise. The reasons are manifold but usually due to a misunderstanding of how virtualization will affect the overall storage throughput of the environment. These issues are not isolated to any particular storage choice or connection protocol. The main reason performance issues occur in a virtual environment is consolidation. The same benefit that allows data centers to remove hundreds of physical servers creates the problem that causes the most headaches. By moving multiple workloads in the form of virtual machines to a single physical host server, we’ve not only aggregated the memory and processing requirements for those workloads, but the ...
