Microsoft® System Center Virtual Machine Manager 2012 Storage Automation With the IBM XIV Storage System Gen3

This technical white paper reviews key concepts and provides step-by-step implementation examples for Microsoft System Center Virtual Machine Manager (SCVMM) 2012 new storage automation features. Microsoft SCVMM 2012 now provides all administrators, including virtualization, database, systems, storage, etc., the ability to perform a full spectrum of core storage management tasks within a true central administrative interface. Within SCVMM’s graphical user interface (GUI), administrators can discover, classify, allocate, provision, map, assign and decommission storage associated with clustered and standalone virtualization hosts. A close examination of popular IBM XIV Storage System Gen3 enterprise-class storage solutions reveals extensibility and performance improvements which align with the Microsoft SCVMM 2012 new features.
