One of the most exciting new features in Windows Server 2008 R2 is the ability to live migrate virtual machines between nodes of a Failover Cluster. In contrast to Windows Server 2008’s Hyper-V this enables admins to failover virtual machines without noticeable downtime.
Admins can use the built-in Cluster Admin (GUI) tools to failover virtual machines at any time. Virtual Machine Manager (VMM), a member of Microsoft’s System Center family, allows for more pro-active deployments and management, beyond the built-in tools.
System Center Virtual Machine Manager (SCVMM) offers:
- A web interface to manage virtual machines, that enables admins to start and stop virtual machines. (Power) Users can also use this functionality, transforming the web interface into a self-service portal.
- PowerShell cmdlets to manage virtual machines from the command line and scripts.
- A library in which you can store virtual machine templates, virtual machine disks and (PowerShell) scripts to easily and fast produce new virtual machines.
- Performance & Resource Optimization (PRO) tips, to integrate with System Center Operations Manager (SCOM) 2007. These tips provide the ability to pro-actively perform actions / run scripts, kicked off by events detected by System Center Operations Manager (SCOM) 2007.
- Intelligent placement and consolidation candidate functionality to make more informed decisions where to place new virtual machines and/or migrate virtual machines to.
- Management of VMWare ESXi and ESX hosts the Microsoft way.
A server license for System Center Virtual Machine Manager (SCVMM) can be purchased as any other Microsoft product, but System Center Virtual Machine Manager (SCVMM) doesn’t require Client Access Licenses (CALs), or Management Licenses (MLs) as they are called in the System Center universe. Virtual Machine Manager (SCVMM) can also be purchased as part of the Systems Management Suite Enterprise (SMSE).
