Assuring Performance in VDI Deployments – The paper focuses on VDI projects, and especially on performance and how to assure that the end users gets a correct performance to his desktop or how to make sure that the existing infrastructure delivers the best performance.
VDI projects are often complex with unpredictable performance results. With a recent survey reporting that 46% of VDI projects are being stalled due to cost and performance issues. This shows the importance of
Coupled with the extremely dynamic nature of virtual desktop workloads, which may be quickly spun up and down, IO demands on the virtual infrastructure can be highly volatile. IO “boot storms” can also be generated when multiple desktop virtual machines come online simultaneously, and significant spikes in IO can result from anti-virus scans across virtual machines.
Assuring Performance in VDI Deployments. VDI workloads needs real time monitoring and and resource allocation in order to match the best the demand. If not the performance suffers.
A proper planning before the project starts – VMturbo has a function which enables to setup a model of VDI desktop and simulate the compute, network or storage loads with this “template”, on existing environment, and get a results for future growths (ex. how many new hosts, or storage devices is necessary to accommodate the future VDI loads). The planning and forecasting can be based on existing infrastructure or planned on a green field deployment.
