Storage Live MigrationLM in WS2012 has multiple aspects
Failover Cluster Live Migration
Shared nothing Live Migration
Storage Live Migration
Only supported when using VHD/VHDX/AVHD/AVHDXPass-through disks are not supported
VM data files can be moved to the same or different locationsLive Storage migration without Virtual Machine Manager (VMM2012)Simultaneous Live storage migration (Customizable)

21.Disk reads and writes are to
the source virtual hard disk when the migration is initiated
2.While reads and writes are still to the source, the disk contents are copiedto the new destination
3.After initial copy completes, reads and writes are mirrored to both sourceand destination
4.When the disks are synchronized, the virtual machine is switched over to the destination
5.The source virtual disks are deleted
Windows Server 2012 adds no downtime migration of VM Storage

New Virtual Hard Disk Format
Native 4K Disk Support Take advantage of enhanced density and reliability
Data TrimmingUnmap support to release SAN space
Larger Block Sizes 32 MB for fixed and dynamic and 2 MB for differential disks
64TB VHDX Increased capacity, protection and alignment optimization
Can be managed using PowerShell

ation ODX
• Data transfer between intelligent storage arrays
• Token based
Benefits• Rapid virtual machine provisioning
and migration• Faster transfers on large files• Latency minimization• Less CPU and network usage• Performance not limited by network
throughput or server usage• Improved data center capacity and
scale• Automation
Restrictions• Requires Storage vendor support• Bitlocker volumes not supported• Only applies to SCSI attached
devices• Compressed or encrypted files not
supported
