1. Virtual Fibre Channel for Virtual Machines
Traditional datacenters have invested a great deal of resources in the provision of storage
infrastructure. In Windows Server 2012, Microsoft makes it easy for you to ensure your
virtualized workloads can connect into your existing storage infrastructure.
Virtual Fibre Channel for Hyper-V, a new feature of Windows Server 2012, provides Fibre
Channel ports within the guest operating system, which provides a direct connection to Fibre
Channel from within your virtual machines. This feature allows you to virtualize your workloads
that require Fibre Channel storage—and also allows you to cluster guest operating systems in
virtual machines using Fibre Channel.
Poster Companion Reference: Hyper-V Storage Page 4
Some key features for using virtual Fibre Channel include:
• It allows you to leverage N_Port ID Virtualization (NPIV).
• Provides unmitigated access to your storage area network (SAN).
• Provides hardware-based I/O path to the Windows software virtual hard disk stack.
• Provides support for your live migration operations.
• It allows you to have a single Hyper-V host connected to different SANs with multiple
Fibre Channel ports.
• You can have up to four virtual Fibre Channel adapters on a virtual machine.
• You can use Multipath I/O (MPIO) to ensure high availability connections to your
storage.
2. Virtual Fibre Channel Adapters
In the past, your virtual machines that were located on a server running Hyper-V® never had the
capacity to directly access the storage hardware. In Windows Server 2012, virtual Fibre Channel
adapters provide port virtualization by exposing host bus adapter (HBA) ports in the guest
operating system. This provides your virtual machine with direct and unfiltered access to a
storage area network (SAN) by using a standard World Wide Name (WWN) that is associated
with your virtual machine.
Windows Server 2012 supports up to four virtual Fibre Channel adapters that can be assigned to
each of your virtual machines.
3. N_Port ID Virtualization (NPIV) Support
Consider a traditional non-virtual environment with respect to Fibre Channel and storage. On
your SAN, you would assign a storage LUN (logical unit number) to a server with an associated
zone. The zone allows a particular server to access that LUN. This relationship is formalized by
assigning the World Wide Name (WWN) of the SAN host bus adapter (HBA) to that LUN. Each
HBA now has its own unique identifier or WWN and this allows secure access to that LUN.
Poster Companion Reference: Hyper-V Storage Page 5
Consider a virtual environment. A zone is assigned to a
WWN on your host bus adapter, but the problem is
your physical Hyper-V server may support multiple
virtual machines. Each virtual machine shares access to
the Hyper-V server’s HBA and, as a result, has the same
WWN identification to the LUN. This does not present a
suitable solution, so a mechanism to identify the
individual virtual machines to the SAN is required. The
solution is known as N_Port ID Virtualization (NPIV).
The diagram on the right illustrates NPIV.
In Windows Server 2012, virtual Fibre Channel for
virtual machines utilizes NPIV technology. An NPIV port
is created on the server running Hyper-V and is
associated with the virtual Fibre Channel adapter. The
WWN assigned to the NPIV port allows all I/O to be
redirected to a specific virtual Fibre Channel adapter in
a virtual machine. In essence, NPIV allows you to have a zone in your SAN that only one virtual
machine can access, just like in the physical world.
4. Live Migration Support for Fibre Channel Connectivity
Hyper-V in Windows Server 2012 now supports live migration of virtual machines across
computers running Hyper-V while maintaining Fibre Channel connectivity (live migration with
failover clusters). This was not possible in previous
releases of Windows Server 2008 and Windows
Server 2008 R2.
The live migration process that maintains Fibre
Channel connectivity is illustrated in the diagram
(right).
Two World Wide Names (WWNs) are configured for
each virtual Fibre Channel adapter in your virtual
machine, Set A and Set B. Hyper-V automatically changes between Set A and Set B WWN
addresses during a live migration. Hyper-V ensures that all logical unit numbers (LUNs) are
available on the destination computer and then performs the live migration. No downtime
occurs during the migration.

5. MPIO Connectivity to Fibre Channel Storage
As more and more data is consolidated on storage area networks (SANs), the potential loss of
access to storage resources is unacceptable. To mitigate this risk, high availability solutions, like
MPIO, have been developed and now extended to virtualized environments.
Microsoft Multipath I/O (MPIO) provides the logical facility for routing I/O over redundant
hardware paths connecting server to storage. These redundant hardware paths can be made
up of components such as the cabling, host bus adapters (HBAs), switches, and storage
controllers and possibly even mains power. MPIO manages these redundant connections so
that I/O requests can be rerouted in the event that a component along one path fails—for
example, a hardware adapter.
6. MPIO on the Virtual Machines
Hyper-V in Windows Server 2012 can use Multipath I/O (MPIO) functionality to ensure
continuous connectivity to Fibre Channel storage from within a virtual machine. You can use
MPIO on virtual machines in co-existence with MPIO on a server running Hyper-V.
7. MPIO on the Server Running Hyper-V
You can also install multiple Fibre Channel ports on the server running Hyper-V and can use
MPIO to provide highly available connectivity to the LUNs that are accessible by the server. This
ensures you are able to cope with a storage component failure that would normally prevent
your system from continuing its normal operations.
8. Device-Specific Modules
Microsoft Multipath I/O (MPIO) is a Microsoft-provided framework that allows storage providers
to develop multipath solutions that contain the hardware-specific information needed to
optimize connectivity with their storage arrays. These modules are called Device-Specific
Modules (DSMs).
9. Hyper-V Using Server Message Block (SMB)
The Server Message Block (SMB) protocol is a network file sharing protocol, as implemented in
the Windows operating system, and is known as the Microsoft SMB protocol. You may also hear
it referred to as the Common Internet File System (CIFS).
Poster Companion Reference: Hyper-V Storage Page 7
Historically, SMB file shares have been perceived as having unreliable connections and
unreliable storage on file servers. However, in Windows Server 2012, this has all changed and
SMB 3 is now a major functionality for inclusion in enterprise customer environments.
In Windows Server 2012, Hyper-V can store virtual machine files (configuration files, virtual hard
disk files, and snapshots) on file servers by using SMB 3. This is supported for both non-
clustered and clustered servers running Hyper-V where file storage is used as shared storage for
the failover cluster.
If you configure virtual machine storage on a central SMB share, you can also perform a live
migration of this virtual machine even when you have not configured a cluster. During the live
migration, the virtual machine is moved from one physical server to another while the storage
remains on the central SMB share.
Storage migration is also possible. If you want to update the physical storage available to your
server running Hyper-V, you can move virtual hard disks both on shared storage subsystems
and on non-shared storage as long as a Windows Server 2012 SMB 3 network shared folder is
visible to both Hyper-V hosts.
SMB 3 allows you to use your file storage resources across virtualization environments. Storing
Hyper-V data on inexpensive, easy-to-manage file servers provides the benefits that you would
expect from a storage area network (SAN)—continuous availability, high performance, and
manageability.
10. Understanding Virtual Hard Disks
A VHD (virtual hard disk) is a file format used in Microsoft virtualization that represents a virtual
hard disk drive. Virtual hard disks allow multiple operating systems to reside on a server running
Hyper-V. It allows your developers to test software on different operating systems without the
cost or hassle of installing a second hard disk or creating a separate partition on a single hard
disk.
Just like a regular disk, a virtual hard disk can contain disk partitions and a file system, which in
turn can contain files and folders. This is the exact same appearance and behavior of the hard
disk of a virtual machine. You can configure virtual machines to use either a fixed-sized virtual
hard disk or a dynamically expanding virtual hard disk or to directly access a physical disk. The
virtual hard disk file functions as a set of disk blocks and is stored as a regular file using the
NTFS file system.
A fixed-size virtual hard disk is a file stored in an NTFS partition that uses the full amount of
space specified when the virtual hard disk was created. However, you can always increase the
Poster Companion Reference: Hyper-V Storage Page 8
size of a fixed-size VHD by using Hyper-V Manager or by running a Windows PowerShell™
script.
Alternatively, a dynamically expanding virtual hard disk is a file stored on an NTFS partition that
grows in size each time data is added. It provides an efficient use of available storage and is the
most commonly used type of virtual hard disk. Keep in mind that you can always compact a
dynamically expanding virtual hard disk, which reduces the size of the virtual hard disk
(represented by the .vhd file) by removing unused space left behind when data is deleted from
the virtual hard disk.
A differencing virtual hard disk is a special type of virtual hard disk that stores changes to an
associated parent virtual hard disk for the purpose of keeping the parent virtual hard disk intact.
Changes continue to accumulate in the differencing virtual hard disk until it is merged to the
parent disk. The parent virtual hard disk of a differencing virtual hard disk can either be a fixed-
size virtual hard disk, a dynamically expanding virtual hard disk, or a differencing virtual hard
disk (differencing chain).
You also have the option of using disk storage that is configured as a physical disk directly
attached to a virtual machine. In addition, disk storage can be configured as a storage area
network (SAN) logical unit number (LUN) attached to a virtual machine. You might also hear
these disks referred to as pass-through disks. From the management operating system
perspective, the disk is in an offline state, which means direct read and write access to the disk is
not available. These disks do not support dynamically expanding virtual hard disks, differencing
virtual hard disks, or virtual machine snapshots.
The main VHD
types are illustrated

11. New Virtual Hard Disk Format
Customer environments are dynamic in nature and storage systems are always evolving. This is
especially true for customers requiring increased reliance on virtualized enterprise workloads. To
address this, Hyper-V in Windows Server 2012 contains an update to the virtual hard disk format
called VHDX. This new format is designed to allow enterprise environments the capacity to cater
for current and future workloads.
The new VHDX format delivers the following capabilities for virtualizing enterprise-class storage
and their associated workloads:
• Supports up to 64 terabytes (TB) of storage capacity.
• Logs updates to the VHDX metadata structures. This provides added resiliency to the
VHDX file in the case of power outages.
• Supports larger block sizes for dynamic and differencing disks, which allows the disks to
be tuned to the needs of virtualized workloads.
• Increases performance for applications and workloads, especially on physical disks that
have a larger sector size than 512 bytes.
• Supports storing custom metadata. For example, you might want to record your
operating system version or any patches you have applied.
• You can also configure and manage virtual hard disks on a computer running Hyper-V
using Windows PowerShell commands.
• Reliably protects against issues for dynamic and differencing disks during power failures.
• Provides efficiency (called trim) in representing data, which results in smaller files and
lets the underlying physical storage device reclaim unused space. (Trim requires pass-
through or SCSI disks and trim-compatible hardware.)
To take advantage of the new version of the new VHDX format, you need the following:
• Windows Server 2012 or Windows 8.
• Server running Hyper-V with the Hyper-V server role.
• Trim-capable hardware.
Poster Companion Reference: Hyper-V Storage Page 10
12. Support for Virtual Hard Disks on Native 4-KB Disks
If you look at disk storage architecture today, you will find the format is to have 512 bytes per
sector. In fact, this has been the case for many years. If you have a sector format where storage
exceeds 512 to 520 bytes per sector, this is referred to as an advanced format. Changing the
sector format to the new 4,096-byte structure (or 4-KB disks) uses the storage surface area more
efficiently. This is true for larger files but less efficient for smaller files. However, you still gain
powerful error correction technology (or algorithms) to maintain the integrity of your data at
much higher storage densities.
In Windows Server 2012, Hyper-V introduces support for 4,096-byte sectors (4-KB disk sectors)
in virtual disks. The 4-KB disk sector format is a standard to which the industry will move toward
over the next few years to support increasing storage requirements.
Introducing a new disk sector format means that methods are required to maintain backward
compatibility with older disk sector formats, especially since 512K sectors are so entrenched in
existing hardware. One approach is to use a new standard known as 512-byte emulation (512e).
Hard drives configured with 4,096-byte physical sectors with 512-byte firmware are often
referred to as 512 emulation drives.
Hyper-V in Windows Server 2012 also provides enhanced performance of the transitional 512-
byte emulation (512e) standard. Support for 4-KB disk sectors and 512e helps ensure that your
virtualization infrastructure keeps pace with industry innovations in storage.

Windows Server Component Architecture Posters To download the poster, see the Windows Server 2012 Hyper-V Component Architecture Poster in the Microsoft® Download Center. This is a free resource. 1. Virtual Fibre Channel for Virtual Machines Traditional datacenters have invested a great deal of resources in the provision of storage infrastructure. In Windows Server 2012, Microsoft makes it easy for you to ensure your virtualized workloads can connect into your existing storage infrastructure. Virtual Fibre Channel for Hyper-V, a new feature of Windows Server 2012, provides Fibre Channel ports within the guest operating system, which provides a direct connection to Fibre Channel from within your virtual machines. This feature allows you to virtualize your workloads that require Fibre Channel storage—and also allows you to cluster guest operating systems in virtual machines using Fibre Channel.
  • 4. Poster Companion Reference: Hyper-V Storage Page 4 Some key features for using virtual Fibre Channel include: • It allows you to leverage N_Port ID Virtualization (NPIV). • Provides unmitigated access to your storage area network (SAN). • Provides hardware-based I/O path to the Windows software virtual hard disk stack. • Provides support for your live migration operations. • It allows you to have a single Hyper-V host connected to different SANs with multiple Fibre Channel ports. • You can have up to four virtual Fibre Channel adapters on a virtual machine. • You can use Multipath I/O (MPIO) to ensure high availability connections to your storage. 2. Virtual Fibre Channel Adapters In the past, your virtual machines that were located on a server running Hyper-V® never had the capacity to directly access the storage hardware. In Windows Server 2012, virtual Fibre Channel adapters provide port virtualization by exposing host bus adapter (HBA) ports in the guest operating system. This provides your virtual machine with direct and unfiltered access to a storage area network (SAN) by using a standard World Wide Name (WWN) that is associated with your virtual machine. Windows Server 2012 supports up to four virtual Fibre Channel adapters that can be assigned to each of your virtual machines. 3. N_Port ID Virtualization (NPIV) Support Consider a traditional non-virtual environment with respect to Fibre Channel and storage. On your SAN, you would assign a storage LUN (logical unit number) to a server with an associated zone. The zone allows a particular server to access that LUN. This relationship is formalized by assigning the World Wide Name (WWN) of the SAN host bus adapter (HBA) to that LUN. Each HBA now has its own unique identifier or WWN and this allows secure access to that LUN.
  • 5. Poster Companion Reference: Hyper-V Storage Page 5 Consider a virtual environment. A zone is assigned to a WWN on your host bus adapter, but the problem is your physical Hyper-V server may support multiple virtual machines. Each virtual machine shares access to the Hyper-V server’s HBA and, as a result, has the same WWN identification to the LUN. This does not present a suitable solution, so a mechanism to identify the individual virtual machines to the SAN is required. The solution is known as N_Port ID Virtualization (NPIV). The diagram on the right illustrates NPIV. In Windows Server 2012, virtual Fibre Channel for virtual machines utilizes NPIV technology. An NPIV port is created on the server running Hyper-V and is associated with the virtual Fibre Channel adapter. The WWN assigned to the NPIV port allows all I/O to be redirected to a specific virtual Fibre Channel adapter in a virtual machine. In essence, NPIV allows you to have a zone in your SAN that only one virtual machine can access, just like in the physical world. 4. Live Migration Support for Fibre Channel Connectivity Hyper-V in Windows Server 2012 now supports live migration of virtual machines across computers running Hyper-V while maintaining Fibre Channel connectivity (live migration with failover clusters). This was not possible in previous releases of Windows Server 2008 and Windows Server 2008 R2. The live migration process that maintains Fibre Channel connectivity is illustrated in the diagram (right). Two World Wide Names (WWNs) are configured for each virtual Fibre Channel adapter in your virtual machine, Set A and Set B. Hyper-V automatically changes between Set A and Set B WWN addresses during a live migration. Hyper-V ensures that all logical unit numbers (LUNs) are available on the destination computer and then performs the live migration. No downtime occurs during the migration.

  • 6. Poster Companion Reference: Hyper-V Storage Page 6 5. MPIO Connectivity to Fibre Channel Storage As more and more data is consolidated on storage area networks (SANs), the potential loss of access to storage resources is unacceptable. To mitigate this risk, high availability solutions, like MPIO, have been developed and now extended to virtualized environments. Microsoft Multipath I/O (MPIO) provides the logical facility for routing I/O over redundant hardware paths connecting server to storage. These redundant hardware paths can be made up of components such as the cabling, host bus adapters (HBAs), switches, and storage controllers and possibly even mains power. MPIO manages these redundant connections so that I/O requests can be rerouted in the event that a component along one path fails—for example, a hardware adapter. 6. MPIO on the Virtual Machines Hyper-V in Windows Server 2012 can use Multipath I/O (MPIO) functionality to ensure continuous connectivity to Fibre Channel storage from within a virtual machine. You can use MPIO on virtual machines in co-existence with MPIO on a server running Hyper-V. 7. MPIO on the Server Running Hyper-V You can also install multiple Fibre Channel ports on the server running Hyper-V and can use MPIO to provide highly available connectivity to the LUNs that are accessible by the server. This ensures you are able to cope with a storage component failure that would normally prevent your system from continuing its normal operations. 8. Device-Specific Modules Microsoft Multipath I/O (MPIO) is a Microsoft-provided framework that allows storage providers to develop multipath solutions that contain the hardware-specific information needed to optimize connectivity with their storage arrays. These modules are called Device-Specific Modules (DSMs). 9. Hyper-V Using Server Message Block (SMB) The Server Message Block (SMB) protocol is a network file sharing protocol, as implemented in the Windows operating system, and is known as the Microsoft SMB protocol. You may also hear it referred to as the Common Internet File System (CIFS).
  • 7. Poster Companion Reference: Hyper-V Storage Page 7 Historically, SMB file shares have been perceived as having unreliable connections and unreliable storage on file servers. However, in Windows Server 2012, this has all changed and SMB 3 is now a major functionality for inclusion in enterprise customer environments. In Windows Server 2012, Hyper-V can store virtual machine files (configuration files, virtual hard disk files, and snapshots) on file servers by using SMB 3. This is supported for both non- clustered and clustered servers running Hyper-V where file storage is used as shared storage for the failover cluster. If you configure virtual machine storage on a central SMB share, you can also perform a live migration of this virtual machine even when you have not configured a cluster. During the live migration, the virtual machine is moved from one physical server to another while the storage remains on the central SMB share. Storage migration is also possible. If you want to update the physical storage available to your server running Hyper-V, you can move virtual hard disks both on shared storage subsystems and on non-shared storage as long as a Windows Server 2012 SMB 3 network shared folder is visible to both Hyper-V hosts. SMB 3 allows you to use your file storage resources across virtualization environments. Storing Hyper-V data on inexpensive, easy-to-manage file servers provides the benefits that you would expect from a storage area network (SAN)—continuous availability, high performance, and manageability. 10. Understanding Virtual Hard Disks A VHD (virtual hard disk) is a file format used in Microsoft virtualization that represents a virtual hard disk drive. Virtual hard disks allow multiple operating systems to reside on a server running Hyper-V. It allows your developers to test software on different operating systems without the cost or hassle of installing a second hard disk or creating a separate partition on a single hard disk. Just like a regular disk, a virtual hard disk can contain disk partitions and a file system, which in turn can contain files and folders. This is the exact same appearance and behavior of the hard disk of a virtual machine. You can configure virtual machines to use either a fixed-sized virtual hard disk or a dynamically expanding virtual hard disk or to directly access a physical disk. The virtual hard disk file functions as a set of disk blocks and is stored as a regular file using the NTFS file system. A fixed-size virtual hard disk is a file stored in an NTFS partition that uses the full amount of space specified when the virtual hard disk was created. However, you can always increase the
  • 8. Poster Companion Reference: Hyper-V Storage Page 8 size of a fixed-size VHD by using Hyper-V Manager or by running a Windows PowerShell™ script. Alternatively, a dynamically expanding virtual hard disk is a file stored on an NTFS partition that grows in size each time data is added. It provides an efficient use of available storage and is the most commonly used type of virtual hard disk. Keep in mind that you can always compact a dynamically expanding virtual hard disk, which reduces the size of the virtual hard disk (represented by the .vhd file) by removing unused space left behind when data is deleted from the virtual hard disk. A differencing virtual hard disk is a special type of virtual hard disk that stores changes to an associated parent virtual hard disk for the purpose of keeping the parent virtual hard disk intact. Changes continue to accumulate in the differencing virtual hard disk until it is merged to the parent disk. The parent virtual hard disk of a differencing virtual hard disk can either be a fixed- size virtual hard disk, a dynamically expanding virtual hard disk, or a differencing virtual hard disk (differencing chain). You also have the option of using disk storage that is configured as a physical disk directly attached to a virtual machine. In addition, disk storage can be configured as a storage area network (SAN) logical unit number (LUN) attached to a virtual machine. You might also hear these disks referred to as pass-through disks. From the management operating system perspective, the disk is in an offline state, which means direct read and write access to the disk is not available. These disks do not support dynamically expanding virtual hard disks, differencing virtual hard disks, or virtual machine snapshots. The main VHD types are illustrated below. Differencing VHD Parent VHD Stores changes Fixed VHD Dynamic VHD Server Running Hyper-V
  • 9. Poster Companion Reference: Hyper-V Storage Page 9 11. New Virtual Hard Disk Format Customer environments are dynamic in nature and storage systems are always evolving. This is especially true for customers requiring increased reliance on virtualized enterprise workloads. To address this, Hyper-V in Windows Server 2012 contains an update to the virtual hard disk format called VHDX. This new format is designed to allow enterprise environments the capacity to cater for current and future workloads. The new VHDX format delivers the following capabilities for virtualizing enterprise-class storage and their associated workloads: • Supports up to 64 terabytes (TB) of storage capacity. • Logs updates to the VHDX metadata structures. This provides added resiliency to the VHDX file in the case of power outages. • Supports larger block sizes for dynamic and differencing disks, which allows the disks to be tuned to the needs of virtualized workloads. • Increases performance for applications and workloads, especially on physical disks that have a larger sector size than 512 bytes. • Supports storing custom metadata. For example, you might want to record your operating system version or any patches you have applied. • You can also configure and manage virtual hard disks on a computer running Hyper-V using Windows PowerShell commands. • Reliably protects against issues for dynamic and differencing disks during power failures. • Provides efficiency (called trim) in representing data, which results in smaller files and lets the underlying physical storage device reclaim unused space. (Trim requires pass- through or SCSI disks and trim-compatible hardware.) To take advantage of the new version of the new VHDX format, you need the following: • Windows Server 2012 or Windows 8. • Server running Hyper-V with the Hyper-V server role. • Trim-capable hardware.
  • 10. Poster Companion Reference: Hyper-V Storage Page 10 12. Support for Virtual Hard Disks on Native 4-KB Disks If you look at disk storage architecture today, you will find the format is to have 512 bytes per sector. In fact, this has been the case for many years. If you have a sector format where storage exceeds 512 to 520 bytes per sector, this is referred to as an advanced format. Changing the sector format to the new 4,096-byte structure (or 4-KB disks) uses the storage surface area more efficiently. This is true for larger files but less efficient for smaller files. However, you still gain powerful error correction technology (or algorithms) to maintain the integrity of your data at much higher storage densities. In Windows Server 2012, Hyper-V introduces support for 4,096-byte sectors (4-KB disk sectors) in virtual disks. The 4-KB disk sector format is a standard to which the industry will move toward over the next few years to support increasing storage requirements. Introducing a new disk sector format means that methods are required to maintain backward compatibility with older disk sector formats, especially since 512K sectors are so entrenched in existing hardware. One approach is to use a new standard known as 512-byte emulation (512e). Hard drives configured with 4,096-byte physical sectors with 512-byte firmware are often referred to as 512 emulation drives. Hyper-V in Windows Server 2012 also provides enhanced performance of the transitional 512- byte emulation (512e) standard. Support for 4-KB disk sectors and 512e helps ensure that your virtualization infrastructure keeps pace with industry innovations in storage.
