Avanade virtualized its databases and consolidate them on fewer servers connected to a 50TB storage solution from NetApp. Overall, they reduced servers by 85% and improved performance by 50%. NetApp, released a whitepaper that discusses their testing with consolidation of multiple workloads: Exchange Server 2007 (2000 heavy users; 250 MB Mailbox), SharePoint 2007 (3000 users; 500MB user quota) and SQL Server 2008 (3000 users using OLTP workloads such as CRM). They used Windows Server 2008 R2 Hyper-V with its Clustered Shared Volume (CSV) technology. They used LiveMigration along with NetApp MetroCluster software for high availability and cross-site disaster recovery. In these their tests, they were able to achieve 100% up-time!
