30 C H A P T E R 2 | Compute Figure 2-25: VM Configuration Version For SOFS servers that have completed the cluster operating system rolling upgrade process, you will also want to upgrade the functionality of the storage pools. They will still be limited to the functionality in Windows Server 2012 R2 until you run the Update-StoragePool cmdlet. Specify the name of the storage pool that you want to update in this process. When you have completed the cluster operating system rolling upgrade on all nodes, updated the cluster functional level, and updated the VM configuration version and storage pool to Windows Server 2016 Technical Preview functionality, you are all done! Gone are the days when you needed to create a new cluster and recreate or move workloads. Cluster Operating System Rolling Update simplifies long-term cluster management and makes those complexities a thing of the past. Hyper-V improvements By Robert Mitchell, Deepak Srivastava, Shabbir Ahmed, and Ramnish Singh Microsoft Hyper-V virtualization technology has been enhanced in a number of ways in Windows Server 2016 Technical Preview, and this section describes several of these improvements. Robert Mitchell demonstrates a new feature called Virtual Machine Groups and also describes the new cross- version VM mobility capabilities of the platform. Deepak Srivastava walks you through the new VM configuration version, new configuration file format, and new support for using checkpoints in production environments. Finally, Shababir Ahmed and Ramnish Singh demonstrate the new hot add and remove capability for network adapters and memory that is now supported by the Hyper-V role. VM groups To make the management of multiple VMs easier, Windows Server 2016 Technical Preview has added support for groupings of VMs. VM groups are exactly what the name implies: logical groupings of VMs. There are two different types of groups: VM collections Management collections A VM collection group is a logical collection of VMs. This type of group makes it possible for administrators to carry out their tasks on specific groups, rather than having to carry them out on each individual VM separately. A management collection group is a logical collection of VM collection groups. With this type of group, administrators can nest VM collections as needed. In Hyper-V Manager, it is possible to carry out operations on multiple VMs simply by selecting multiple objects, as illustrated in Figure 2-26.
