    DATA CENTER Virtual Fibre Channel for Hyper-V Virtual Fibre Channel for Hyper-V, a new technology available in Microsoft Windows Server 2012, allows direct access to Fibre Channel (FC) shared storage by multiple guest virtual machine (VM) partitions. Combined with the Brocade cloud-optimized Fibre Channel Storage Area Network (SAN) infrastructure, this new capability simplifies connectivity between Fibre Channel SAN storage and Hyper-V applications and offers unprecedented levels of availability, scalability, and operational efficiency for virtualized workloads and cloud architectures.  DATA CENTER TECHNICAL BRIEF Virtual Fibre Channel for Hyper-V 2 of 11 CONTENTS Contents ................................................................................................................................................................................................................................................ 2   Introduction ......................................................................................................................................................................................................................................... 3   Technology Overview ........................................................................................................................................................................................................................ 4   Technology Requirements .............................................................................................................................................. 4   Use Cases ........................................................................................................................................................................ 4   Distributed Workload Clustering .................................................................................................................................... 4   Live Migration .................................................................................................................................................................. 5   MPIO Functionality .......................................................................................................................................................... 5   Virtual SAN Support ......................................................................................................................................................... 6   The Brocade Advantage ................................................................................................................................................................................................................. 7   Highest Levels of Availability .......................................................................................................................................... 7   Unmatched Performance and Scalability ...................................................................................................................... 7   Operational Efficiency ..................................................................................................................................................... 9   Conclusion ......................................................................................................................................................................................................................................... 11    DATA CENTER TECHNICAL BRIEF Virtual Fibre Channel for Hyper-V 3 of 11 INTRODUCTION To gain the full benefits of server virtualization and cloud architectures, virtualized workloads need to connect easily and reliably to existing SANs. For many enterprise organizations, Hyper-V deployments were limited in scale and scope because they lacked the ability to directly connect VMs to Fibre Channel SAN storage from inside a VM. Hyper-V in Windows Server 2012 now provides virtual Fibre Channel Host Bus Adapter (HBA) ports within the guest operating system that runs the virtual machine, connecting virtual machines directly to Fibre Channel SAN Logical Unit Numbers (LUNs). Virtual Fibre Channel for Hyper-V provides several important advantages for Hyper-V environments: ã   Simplifies storage connectivity for virtualized workloads to ultra-reliable, high-performance Fibre Channel SAN storage ã   Enables new solutions that require shared storage, such as failover clustering, live migration, and multipath I/O ã   Leverages and protects existing investments in Fibre Channel storage ã   Enables advanced FC SAN storage functionality for VMs o   Facilitates migration of FC workloads into the cloud o   Enables improved monitoring and troubleshooting, with visibility from the VM to the FC SAN storage o   Enables centralized management of Ethernet and FC-based virtualized workloads Combining Virtual Fibre Channel for Hyper-V and the Brocade ®  Fibre Channel SAN infrastructure greatly simplifies connectivity between Fibre Channel SAN storage and virtualized applications, enabling enterprise IT and hosting providers to achieve new levels of availability, reliability, and scalability for cloud-based services.  DATA CENTER TECHNICAL BRIEF Virtual Fibre Channel for Hyper-V 4 of 11 TECHNOLOGY OVERVIEW Virtual Fibre Channel for Hyper-V (also referred to as Synthetic Fibre Channel) provides VM guest operating systems with direct access to a Fibre Channel SAN by using a standard World Wide Name (WWN) associated with a virtual machine. With this new capability, Hyper-V users can now use Fibre Channel SANs to virtualize workloads that require direct access to SAN LUNs. Fibre Channel SANs also allow you to deploy new solutions, such as running the Failover Clustering feature inside the guest operating system of a virtual machine connected to shared Fibre Channel storage. Mid-range and high-end storage arrays are capable of advanced storage functionality that helps offload certain management tasks from the hosts to the FC SAN. Virtual Fibre Channel presents an alternate hardware-based I/O path to the Windows software virtual hard disk stack, allowing the use of advanced functionality offered by FC SAN storage directly from Hyper-V virtual machines. For example, you can use Hyper-V to offload storage functionality—like taking a snapshot of a LUN--on the FC SAN hardware by using a hardware-based Volume Shadow Copy Service (VSS) provider from within a Hyper-V virtual machine. Virtual Fibre Channel for Hyper-V guests use the existing N_Port ID Virtualization (NPIV) T11 standard to map multiple virtual N_Port IDs to a single physical Fibre Channel N_Port. A new NPIV port is created on the host each time you start a virtual machine that is configured with a virtual HBA. When the virtual machine stops running on the host, the NPIV port is removed. Technology Requirements Brocade SAN environments using Virtual Fibre Channel for Hyper-V require the following: ã   One or more installations of Windows Server 2012 with the Hyper-V role installed. Hyper-V requires a computer with processor support for hardware virtualization. ã   A computer with one or more Fibre Channel HBAs with HBA driver support for Virtual Fibre Channel. While the solution works with any HBA that supports Virtual Fibre Channel, updated Brocade HBA drivers are included in-box with Windows Server 2012 to simplify deployment. The HBA ports to be used with virtual Fibre Channel should be set up in a Fibre Channel topology that supports NPIV. ã   A Brocade NPIV-enabled SAN ã   Virtual machines configured to use a virtual Fibre Channel adapter, which must use Windows Server 2008, Windows Server 2008 R2, or Windows Server 2012 as the guest operating system ã   Storage accessed through virtual Fibre Channel support devices that present LUNs. Virtual Fibre Channel LUNs cannot be used as boot media. Use Cases Virtual Fibre Channel for Hyper-V allows the direct connection to Fibre Channel LUNs from within a virtual machine, allowing the use of existing Fibre Channel investments for Hyper-V virtualized workloads. Virtual Fibre Channel for Hyper-V also enables the use of any advanced storage functionality directly from the VMs. In addition, Virtual Fibre Channel enables many new related capabilities, including distributed workload clustering, live migration, Multipath I/O (MPIO), and virtual SANs, which are briefly discussed later in this document. Distributed Workload Clustering Clustering applications such as Microsoft Exchange or SQL Server that are running on multiple VMs allows workloads to be distributed between VMs. Clustering high availability applications in this way allows workload balancing for increased utilization and efficiency, as well as performing routine maintenance of individual VMs without disturbing the workload. In the event of an application failure, the application can be migrated to another VM without any disruption. The new Virtual Fibre Channel feature allows VM clustering across a Fibre Channel SAN, allowing clustered Microsoft Exchange, SQL Server and other key applications to leverage a highly available, highly resilient, and highly scalable FC SAN infrastructure.
