1-Introduction System Center Virtual Machine Manager Machine Manager 2008 R2, helps realize the vision of the dynamic data center. Follow this link to learn about Microsoft Windows Server 2008 R2 Hyper-V: http://www.microsoft.com/windowsserver2008/en/us/hyperv-r2.aspx System Center Virtual Machine Manager System Center Virtual Machine Manager (VMM) 2008 R2 is a comprehensive, heterogeneous management solution for the virtualized data center.
1-Introduction N_Port ID Virtualization (NPIV) This document focuses on NPIV SAN migration. N_Port ID Virtualization (NPIV) N_Port ID Virtualization, or NPIV, is a Fibre Channel technology that allows multiple N_Port IDs to share a single physical N_Port. N_Port sharing allows multiple Fibre Channel initiators to utilize a single physical port, reducing hardware requirements in SAN design, especially where virtual SANs are used.
1-Introduction Value of NPIV in IT Strategy and Best Practices Value of NPIV in IT Strategy and Best Practices Fibre Channel NPIV technology maps effectively to Microsoft‘s key IT strategies driving today‘s data centers. Effective deployment of NPIV-based Fibre Channel SANs in a Windows Server 2008 R2 Hyper-V data center delivers the following strategic IT requirements: Agility. VM migrations are accomplished flexibly without having to reconfigure the SAN cabling.
1-Introduction QLogic Fibre Channel Adapter NPIV Solution With the combined QLogic and Microsoft solution, storage administrators can create virtual adapter ports and assign them to VMs for migration without having to reconfigure any zoning or LUN masking settings. This solution creates a virtualized network that is easy to manage and maintain. Benefits of the QLogic NPIV solution include: Lower TCO. One physical adapter can support multiple virtual WWNs.

2-NPIV SAN Migration: Server Preparation Sample Solution Configuration Sample Solution Configuration Figure 2-1 Quick Migration Configuration Example is an example of an NPIV configuration that uses all of the system elements discussed earlier in this section. A real-life data center is a more complex version of the same configuration. Figure 2-1.
2-NPIV SAN Migration: Server Preparation Installing the Software 1. Install Windows Server 2003 R2 SP2 and set it up as the domain controller and DNS server. Details for this setup are beyond the scope of this document. In this example, domain ―hypernpiv.com‖ has been created. NOTE: Windows Server 2008 or Windows Server 2008 R2 can also be used and configured for this purpose. 2.
2-NPIV SAN Migration: Server Preparation Installing the Software 3. Activate the required Windows Server 2008 R2 roles, services, and features, as shown in the Figure 2-3 to 2-6. Figure 2-3. Roles Installed in Each Hyper-V Host Server NOTE: Each Hyper-V host server that will host the VM needs to have at least three key server roles installed. These include Hyper-V, File Services, and Web Server (IIS).
2-NPIV SAN Migration: Server Preparation Installing the Software Figure 2-4.
2-NPIV SAN Migration: Server Preparation Installing the Software The installed server features are summarized in Figure 2-5. They are consistent with the VMM2008 R2 (RC) requirements. The required and recommended features include: Windows Multipath IO .NET Framework 3.5.1 Background intelligent transfer service (BITS) Remote Server administration tools Storage manager for SANs Remote assistance Figure 2-5.
2-NPIV SAN Migration: Server Preparation Installing the Software NOTE: In addition to enabling the Multipath I/O feature, ensure that the storage array is added as a device within the MPIO Properties dialog box, as shown in Figure 2-6. Figure 2-6. MPIO Properties 2-8 4. Install the QLogic driver and SANsurfer agent on the Hyper-V hosts. 5. Install the HP VDS hardware provider on the Hyper-V host servers. 6.
3 Fibre Channel SAN Preparation Introduction This section assumes that you are familiar with QLogic‘s SANsurfer FC HBA Manager tool and have already created a virtual host bus adapter port on the Fibre Channel host bus adapter installed in hostservera. NOTE: The host name hostservera is alternatively displayed as HostserverA in other applications within this document. Details of this procedure are available in the Fibre Channel HBA & VM Migration Guide for Hyper V & SC VMM2008.
3-Fibre Channel SAN Preparation Virtual Host Bus Adapter Port Creation and SAN Zoning Alternatively, the SAN can be configured as two zones, with one host server and storage array in Zone 1 and the second host server and storage array in Zone 2. This configuration ensures that both host servers can see any LUNs presented (mapped) to them through the storage array. In Figure 3-1, the virtual adapter port is created on the adapter installed on hostservera. Figure 3-1.
3-Fibre Channel SAN Preparation Host Presentation (Mapping) of Storage LUN The zoning configuration in Figure 3-2 shows two adapter ports: one virtual adapter port and one storage controller port in a single zone, for a total of four Fibre Channel ports. NOTE: As a best practice, place all servers in a single zone to ensure that the storage is visible across the entire SAN. The virtual host bus adapter port in this example is 21:f9:00:1b:32:16:fe:ec Figure 3-2.
3-Fibre Channel SAN Preparation Host Presentation (Mapping) of Storage LUN After creating a LUN, mount a volume in the LUN. (For more information, see the HP storage array documentation). NOTE: The LUN must be an NTFS formatted LUN. The LUN is then mapped (or presented/masked) to the host server. For the HP MSA array, this is accomplished by mapping the LUN to the host bus adapter port, as shown in Figure 3-3. Figure 3-3.
3-Fibre Channel SAN Preparation Host Presentation (Mapping) of Storage LUN In Figure 3-4, the LUN is mapped/presented/masked to the host 21:f9:00:1b:32:16:fe:ec . Figure 3-4.
3-Fibre Channel SAN Preparation Host Presentation (Mapping) of Storage LUN View the Storage Manager for SANs snap-in to confirm that the LUN is visible to the host hostservera (see Figure 3-5). Figure 3-5.
4 VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration Microsoft System Center VMM2008 R2 is used for the creation and migration of Virtual Machines (VMs) with configurations based on user requirements. The key steps to enable and execute an NPIV SAN migration are: 1. Adding Hyper-V hosts to VMM2008 R2. 2. Creating a NPIV SAN migration-capable VM on the previously created storage LUN. 3. Performing an NPIV SAN VM migration from the source to the destination Hyper-V host using NPIV technology. 4.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Creation Figure 4-1. Hosts Added to VMM2008 R2 In Figure 4-1, the hosts win-3f1kc24knkr.hypernpiv.com and HostServerA.hypernpiv.com have been added. VM Creation This section describes the additional steps needed to create a VM on a Fibre Channel SAN LUN presented to a virtual adapter port.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Creation VMM2008 R2 automatically mounts the appropriate volumes during the migration process. Do not try to manually mount volumes that have previously been migrated using Disk Manager. To create an NPIV SAN migration-capable VM: 1. In the VMM2008 R2 Actions pane, click New virtual machine to begin the creation of a virtual machine. 2.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Creation In this example, a new VM will be created on a blank virtual hard disk (VHD)—the VHD that will be stored on the SAN LUN. The wizard steps you through the process by following the list shown on the left frame of the dialog box beginning with Select Source and concluding with Summary. 3. Enter the VM name, as shown in Figure 4-3. Figure 4-3.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Creation 4. Configure the hardware profile for the VM (see Figure 4-4). Figure 4-4.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Creation 5. Click Next until the Select Destination dialog box opens. Ensure that the Place Virtual Machine on host button is selected (see Figure 4-5). Figure 4-5. Select Destination 6. Click Next. The Select Virtual Machine Host dialogue box opens. Verify that the Transfer type column has a SAN entry for the host you want to select. Check the SAN Explanation tab to ensure that there are no warnings other than for iSCSI.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Creation 7 Click Next. The Select Path dialog box opens (see Figure 4-6). By default, a path on the local hard drive of the host server is shown. The path specified in this box determines where the virtual hard drive that contains the operating system image of the VM resides. Figure 4-6. Select Path NOTE: The VM files are on the storage LUN that was previously masked/presented to the virtual host bus adapter port created on this host.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Creation Figure 4-7 is an example of the Summary page that displays the VM settings. Figure 4-7. Summary Best Practices to Configure LUNs and Volumes Follow these best practices to configure a LUN and a volume for each VM you want to transfer on a SAN. 4-8 Configure each LUN as a fixed disk. A VM on a LUN mapped to dynamic disks cannot be transferred on a SAN. Create a single volume on each disk.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Creation Format the volume with the NTFS file system. When performing SAN transfers, ensure that the selected destination path is on a volume that is also formatted with NTFS. Place a single VM and all its associated files on each volume. Store only one VM on a volume, since all files are relocated during a SAN transfer. In Figure 4-8, the newly created VM on host HostServerA is now visible in the Virtual Machines view. Figure 4-8.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Creation Similarly, as shown in Figure 4-9, there are no VMs on the second host win3fikc24knkr. Figure 4-9.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Migration VM Migration As shown in Figure 4-10, VM migration is invoked by right-clicking the selected VM (vm22 in this example), and then selecting Migrate from the drop-down menu. Figure 4-10.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Migration The Migration Virtual Machine Wizard opens and leads you through the following steps: 1. Select the location to migrate (destination host) from the list in Figure 4-11. Note that the current host is HostServerA. In this example, the VM will be migrated to server win-3f1kc24knk3. Note that the transfer type for each host is SAN. Figure 4-11. Select Host – Virtual Machine Wizard 2. 4-12 Click Next when you are done.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Migration The Select Path dialog box opens (Figure 4-12). Figure 4-12. Select Path – Virtual Machine Wizard 3. Select the storage locations on the host for the virtual machine files in the Virtual machine path box by either typing the path or clicking Browse and navigating to the path (Figure 4-12). Do not select the Transfer over the network option. This ensures that the VM transfer (migration) will be a SAN transfer.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Migration 4. Click Next when you are done. 5. The Summary dialog box opens (Figure 4-13). Figure 4-13. Summary – Virtual Machine Wizard Review the summary. 6. 4-14 Click Move to initiate the NPIV SAN migration.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration VM Migration 7. Click Jobs to see the details of the migration (see Figure 4-14) before completing the VM migration. The job details screen clearly indicates a SAN migration from the selected host server to the selected target server. Figure 4-14.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration NPIV SAN Migration Confirmation NPIV SAN Migration Confirmation After migration, use QLogic‘s SANsurfer FC HBA Manager tool to confirm that the virtual port, initially created on the physical adapter that was installed in server HostServerA, has now moved to Server win-3fikc24knkr (see Figure 4-15). Figure 4-15.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration NPIV SAN Migration Confirmation After migration, the selected VM (vm22) is now hosted on the server win3fikc24knkr (see Figure 4-16). This is the server that was previously selected as the destination host for the migration. Figure 4-16.
4-VMM2008 R2 Setup, VM Creation, and NPIV SAN Migration NPIV SAN Migration Confirmation Windows Server Disk Management validates that the volume originally associated with host HostServerA is now on the server win-3fikc24knkr (see Figure 4-17). Figure 4-17.

Part II Resolving Fibre Channel Adapter Saturation on Hyper-V Workloads This part of the document contains the following section: Section 5, QLogic Management PRO Pack and NPIV Technology, explains why combining the QLogic Management PRO Pack (for VMM2008 R2) and NPIV technology resolves Fibre Channel adapter saturation on Hyper-V workloads.
II-Resolving Fibre Channel Adapter Saturation on Hyper-V Workloads Notes II-2
5 QLogic Management PRO Pack and NPIV Technology Overview Increasing server consolidation results in multiple workloads exercising the capabilities of the host server Fibre Channel adapter. High I/O workloads, such as Microsoft® SQL Server® data management software or Microsoft Exchange Server e-mail messaging and collaboration software, may coexist with high throughput workloads, such as backup, on the same host running Microsoft Hyper-V virtualization technology.
5-QLogic Management PRO Pack and NPIV Technology Solution http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/SearchByProduct.
5-QLogic Management PRO Pack and NPIV Technology PRO Pack Benefits A PRO Tip is generated when a virtual or physical port‘s IOPS or data rate Mbps activity exceeds a configurable threshold level for a defined time trend/period. Whether the tip is generated by the virtual or physical port depends on the configuration used by the administrator. The threshold is a function of the adapter‘s capacity.

Part III Using the Hyper-V Pass-through Disk Option This part of the document contains the following section: Section 6, Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology, explains the advantages of using a pass-through disk and how to deploy this method with Hyper-V pass-through storage and QLogic Fibre Channel NPIV technology.
III-Using the Hyper-V Pass-through Disk Option III-2
6 Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology Overview A Hyper-V host server running Windows Server 2008 R2 supports several types of storage connectivity options, including direct-attached storage (SATA, SAS) and SAN storage (Fibre Channel, iSCSI). After the storage disks are exposed to the host, they can be exposed to the guest virtual machine (VM) in different ways.
6-Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology Configuration The combination of QLogic Fibre Channel adapters (with NPIV technology) and Hyper-V‘s pass-through disk option deliver the following benefits: Application isolation, consistent with storage best practices, when the VM runs a single application. Near-native storage I/O performance for virtual machine workloads. (See http://www.qlogic.com/promos/products/hyper-v.aspx for more details.
6-Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology Configuration Steps Configuration Steps Follow these steps to present pass-through storage to two VMs on NPIV-masked Fibre Channel storage LUNs (as shown in Figure 6-1). 1. Create two virtual NPIV ports on a single QLogic 4/8Gb Fibre Channel adapter using the QLogic SANsurfer application.
6-Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology Configuration Steps 3. Create two VMs using the Windows Server 2008 R2 Hyper-V Manager MMC snap-in console (see Figure 6-3). Figure 6-3. Two VMs (VM1 and VM2) Created Using the Hyper-V Manager MMC (Alternately, use Microsoft System Center VMM2008 R2). The VM VHDs are located on two of the LUNs created in Step 2.
6-Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology Configuration Steps 4. Initialize the two storage LUNs on the Hyper-V parent host, and then take them offline (see Figure 6-4). Figure 6-4.
6-Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology Configuration Steps 5. Add the LUNs as pass-through storage disks for each VM, attached to a SCSI controller. In Figure 6-5, VM1 is configured for pass-through storage to Disk 2, which is offline in the host server. Figure 6-5.
6-Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology Configuration Steps 6. Map (present) each of the two VM LUNs to each of the Fibre Channel adapter‘s NPIV ports (see Figure 6-6). Figure 6-6.
6-Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology Configuration Steps 7. Map the two pass-through storage LUNs to the same corresponding NPIV ports of the Fibre Channel adapter, as shown in Figure 6-7. Figure 6-7. Storage LUN (Pass-through 1) Mapped to the Same Virtual Adapter Port (21-F9-00-1B-32-16-FE-EC) that Maps VM1 8. 6-8 Initiate and run storage I/O from each VM to its configured pass-through storage.
6-Hyper-V Pass-Through Storage and QLogic Fibre Channel NPIV Technology Viewing and Managing Storage I/O Quality of Service NOTE: Ensure that the host and the guest are not trying to use the pass-through disk concurrently; Hyper-V requires that the disk be offline on the host. Therefore, the pass-through storage must be offline in the Hyper-V host server (parent partition) before the VM guest can be configured to access it using the pass-through method. Maintain one VM per LUN for I/O isolation.
