Lab Validation: EMC Symmetrix VMAX and Microsoft Server Virtualization Scalability
While a growing number of organizations have taken advantage of the tremendous efficiency and savings that can be realized with server virtualization technology, broad-based adoption throughout the data center often stalls due to a number of challenges including scalability, reliability, and ease of deployment. This report documents how EMC VMAX storage, combined with Microsoft Cluster Shared Volumes (CSV) and Hyper-V R2 server virtualization technology, can be used to addresses those challenges as it supports up to 1,024 virtual machines running on a consolidated, enterprise-class infrastructure.
Server virtualization has made giant strides over the past decade, creating heroes inside IT organizations. Accordingly, it’s no surprise that interest in server virtualization remains as strong as ever. Indeed, respondents to a recent ESG survey ranked “increased use of server virtualization” as their number one IT priority over the next 12- 18 months.1 However, despite the broad success of server virtualization, nagging issues and challenges exist. As a result, a low percentage of the potential workloads that can be virtualized have been migrated to virtual machines and the consolidation ratios of virtual machines per physical server remains relatively low. Challenges that are blocking the next wave of virtualization and consolidation include concerns about scalability, performance, reliability, and ease of deployment.
A recent ESG survey of North American enterprise and larger midmarket IT professionals explored the storage challenges associated with server virtualization.2 Given the rapid growth in the number of virtual machines being deployed, it’s no surprise that scalability, performance, and the overall volume of storage capacity have been identified as key challenges.
