Nadat eerder al Microsoft een rapport had gepubliceerd over de performance-effecten van SQL Server in een Hyper-V omgeving, heeft nu ook VMware een performance studie uitgevoerd. In dit geval gaat het uiteraard om de ESX hypervisor en over de vraag hoe schaalbaar zo’n omgeving is bij de inzet van SQL Server.
De conclusie van het onderzoek luidt:
Experiments discussed in this paper demonstrate the highly scalable virtualization platform provided by ESX 3.5 for consolidating servers running SQL Server databases. Results shown indicate the efficiency of ESX in distributing the processing power available on modern large multi-way servers among multiple virtual machines, resulting in a very high utilization of the systems. While doing so, ESX provides each virtual machine a near-native experience through isolation and guaranteed resource allocation. ESX seamlessly handles variations in demand for resources when the application load in the virtual machines fluctuate, while at the same time preventing resource hogging by a few virtual machines causing starvation for others in a shared environment. Just like native platforms, applications continue to meet or exceed their service levels on a virtualized platform using ESX 3.5, but at much lower cost. All these traits make ESX 3.5 an excellent choice for consolidating servers running SQL Server databases.
