SC 2012 SP1 – VMM provides the ability to deploy and manage third-party switch extensions, such as Cisco 1KV and InMon. For organizations that have investments in these third-party products, these can be integrated into VMM.
Configuring Fabric Resources in VMM - Storage SC 2012 SP – VMM now supports file shares that leverage the new 3.0 version of the Server Message Block (SMB) protocol that is introduced in Windows Server 2012. VMM in this release includes support for designating network file shares on Windows Server 2012 computers as the storage location for virtual machine files, such as configuration, virtual hard disk (.vhd/.vhdx) files and checkpoints.
SMB 3.0 file shares provide the following benefits when they are used with VMM in this release:
You can create SMB 3.0 file shares on standalone Windows Server 2012 file servers and on clustered Windows Server 2012 file servers. If you use a standalone file server, you can designate an SMB 3.0 file share as the virtual machine storage location on a Windows Server 2012 Hyper-V host cluster. However, this is not a highly available solution.
For more information about SMB 3.0 in Windows Server 2012, see Server Message Block Overview.
For more information about how to create a highly available SMB 3.0 file share, see Scale-Out File Server for Application Data Overview, and steps 1 and 2 of the Deploy Scale-Out File Server scenario that is linked to from that topic.
The new Windows Standards-Based Storage Management service replaces the Microsoft Storage Management Service in System Center 2012 – Virtual Machine Manager. The new service uses the Windows Storage Management application programming interface (API), a WMI-based programming interface that is included in Windows Server 2012. This new API enables you to discover storage by using multiple provider types.
The Windows Storage Management API supersedes the Virtual Disk Service (VDS) interface. Therefore, if you are using a storage array that uses only the VDS hardware provider (and not SMI-S), storage area network (SAN) transfer capabilities will no longer be available. A SAN transfer enables you to migrate a virtual machine from one location to another when the virtual hard disk is located on a storage array. The logical unit number (LUN) that contains the virtual machine is remapped from the source computer to the destination computer instead of transferring the files over the network.
In this release, VMM supports the following types of storage providers and arrays:
Configuring Storage Overview
Now with SP1 there is support for auto (dynamic) iSCSI target systems, such as the Dell EqualLogic PS Series. System Center 2012 – Virtual Machine Manager supports only static iSCSI target systems.
Thin provisioning of logical units through VMM is now possible. Your storage array must support thin provisioning and thin provisioning must be enabled for a storage pool by your storage administrator.
SC 2012 SP1 – VMM supports integration with third-party SANs and file-based storage on a Windows Server 2012 file server.
Configuring Fabric Resources in VMM - Hyper-V SC 2012 SP1 – VMM now supports using a virtual hard disk that is in the .vhdx format as the base operating system image.
Also new is operating system deployment that utilizes deep discovery and Consistent Device Naming (CDN). CDN allows VMM to predictably assign network interface controllers (NICs) to the correct networks and teams.
During the discovery process, you can run deep discovery to see more detailed information about the physical computer hardware before you deploy the operating system. In this release, deep discovery functionality is only partially enabled. You can view the physical network adapter information, information about the CPU, and the amount of memory. You can configure network options such as logical switches, and you can change the settings for the network adapter that VMM automatically designates as the management network adapter.

SC 2012 SP1 – VMM also provides support for
Virtual Machines and Services SC 2012 SP1 – VMM provides support for deployment of services to virtual machines in a domain or workgroup that does not have a trust relationship with the domain of the VMM management server.
Preparing to Create Services in VMM
In Hyper-V only, support is provided for the deployment of services to virtual machines that are not connected, where the service instance does not have network connectivity to the VMM management server, to a VMM library server, or to both.
Now in SC 2012 SP1 – VMM when you are deploying a virtual machine as part of a service and creating a SQL Server profile, there is added support for SQL Server 2012 as an instance of Microsoft SQL Server.

SC 2012 SP1 – VMM adds support for the new version of the virtual hard disk format that is introduced in Windows Server 2012. This new format is referred to as VHDX. Compared to the older VHD format, VHDX has a much larger storage capacity of up to 64 TB. The VHDX format also provides data corruption protection during power failures. Additionally, it offers improved alignment of the virtual hard disk format to perform well on large-sector physical disks.
Support for VHDX includes the following:
For more information about the benefits of the VHDX format in Windows Server 2012, see Hyper-V Virtual Hard Disk Format Overview.
Rapid Provisioning of Virtual Machines Using SAN Copy Overview
You can now provision a physical computer as a Hyper-V host. When you provision a physical computer as a Hyper-V host, you can use a Windows Server 2012-based virtual hard disk that is in the .vhdx or .vhd format as the base operating system image.
For background information about adding a physical computer as a Hyper-V host, see Adding Physical Computers as Hyper-V Hosts Overview.
Linux-based virtual machines are now fully supported with the following:
Important: These settings are supported only when the Linux virtual machine is deployed on Hyper-V.

Live Migration SC 2012 SP – VMM supports live migration outside a cluster. This is in addition to supporting live migration within a cluster. Live migration outside a cluster allows you to perform live migration between two standalone computers that are not cluster nodes.
For more information about live migration in Windows Server 2012, see the following topics:
Live migration between nodes in two different clusters is also now supported. You can migrate between nodes within a cluster, or between nodes in different clusters.
Migrating Virtual Machines and Storage Overview
How to configure live virtual machine and storage migration in System Center SP1 - Virtual Machine Manager
Storage migration, which allows for the migration of virtual machine storage is now supported. You can migrate storage in order to update the physical storage available in Hyper-V, or to mitigate bottlenecks in storage performance. Storage can be added to either a standalone computer or a Hyper-V cluster. Then, virtual machines can be moved to the new storage while they continue to run.
SC 2012 SP1 – VMM also supports live VSM. By using live virtual system migration (VSM) you can migrate both virtual machines and storage in a single action.
You can perform multiple concurrent live migrations of virtual machines and storage. The allowable number of concurrent live migrations can be configured manually. Attempted concurrent live migrations in excess of the limit will be queued.
VMM Console Integration of third-party user interface (UI) add-ins for the VMM console can now extend the functionality of the console. For example, you can create console add-ins that will allow you to do the following:
Virtual Machine Manager Add-in SDK in the TechNet Wiki.
There are several significant performance enhancements to the VMM console. Load times are decreased and the performance of sorting and filtering views is significantly improved. For viewing job history, jobs are now loaded incrementally and the views have a richer set of data-filtering options, reducing the effect of large sets of jobs on console performance.
Overview pages in the VMM console now display various reports about usage and capacity metrics for services, tenants and clouds.
