Hi, I work with organizations that use both, properly configured both hypervisors perform well. From a cost perspective ESX is more expensive<http://www.microsoft.com/en-us/server-cloud/windows-server/hyper-v-benefits.aspx> to license, you get live migration and clustering for free with Hyper-V Server 2008 R2.
Whether you are physical or virtual you may still want to cluster your SQL Server, if a node fails the virtual machines on that node effectively reboot on another node in the cluster. I have done both types of clustering and the answer is always it depends on your requirements, you can achieve near bare metal performance with a hypervisor now-a-days. Making sure your SQL Server is configured properly<http://technet.microsoft.com/en-us/library/cc298801.aspx> has to be done regardless of whether your SQL Servers are virtual or bare metal. Here you can find more resources about virtualizing SharePoint: http://sharepoint.microsoft.com/en-us/product/Related-Technologies/Pages/virtualize-sharepoint.aspx Wes From: ozmoss-boun...@ozmoss.com [mailto:ozmoss-boun...@ozmoss.com] On Behalf Of Trevor Andrew Sent: February-23-12 10:13 PM To: ozmoss@ozmoss.com Subject: RE: Virtualization preferences for a new SharePoint Farm Hi All, I should preface my questions by saying that I am *not* an infrastructure specialist, but a SharePoint Architect and Conslultant, and am in the process of specifying the infrastructure for a new SharePoint 2010 production farm within the organisation I work, and the question of any virtualization preferences for the farm have arisen in two senses: 1. We are free to choose either VMWare ESX Server Technology, or Microsoft HyperV. I'd appreciate any feedback positive or negative on either platform. I have personally had a recent bad experience in the VMWare world with the VMWare "Ballooning" memory management causing a SharePoint installation to run very poorly, but I assume that was simply inadvisable resource allocation by those managing the environment. However any advice one way or the other about the preferred virtualization platform would be much appreciated. 2. My recollection from several years ago, is that it would generally have been considered wise to recommend that the SQL Server cluster supporting such a SharePoint Farm remain on physical servers. What are others doing these days? Are you tending to virtualise your SQL Server Server clusters supporting SharePoint, or also virtualizing these as well? This cluster will be a new SQL Server 2008 R2 cluster, as the other SQL Server instances / clusters within the organisation are not of an appropriate version or architecture to support SharePoint 2010. Any feedback on these issues would be much appreciated. Cheers, Trevor Andrew
