NPIV with Brocade HCM and Microsoft Hyper-V 2 of 12    DATA CENTER TECHNICAL BRIEF I NTRODUCTION   This document is a guide to configuring Microsoft ®  Hyper-V using NPIV with a Brocade ®  Fibre Channel to PCIe Host Bus Adapter (HBA). It will help you understand what you need to consider before deploying this solution and how to implement and diagnose NPIV with Hyper-V. It is designed for Windows System Administrators and Storage Administrators. A basic understanding of how to use Windows, Microsoft System Center Virtual Machine Manager (SCVMM), Fibre Channel (FC) storage, and zoning is assumed. About NPIV NPIV stands for N_Port ID Virtulization. It provides a simple, high-availability capability. NPIV uses Host Bus  Adapter (HBA) technology, which creates virtual HBA ports on hosts by abstracting the underlying physical port. This support enables a single physical Fibre Channel HBA port to function as multiple logical ports, each with its own identity. Each virtual machine can then attach to its own virtual HBA port and be independently zoned to a distinct and dedicated World Wide Port Name (WWPN). (http://technet.microsoft.com/en-us/library/cc764269.aspx)) For more information about NPIV and HBA technology, refer to your HBA vendor documentation. There are three options for High Availability (HA) in your Storage Area Network (SAN):    Microsoft Clustering Services (MCS)    Virtual Disk Service (VDS)    NPIV Microsoft SCVMM determines how to migrate a machine based on the following criteria:    If Clustering is enabled, it uses MCS to migrate the guest and re-configure the clustering storage.    If Clustering is not enabled, it uses VDS to re-configure the storage to re-map that LUN to the new World Wide Name (WWN) of the target machine.    If neither Clustering nor VDS is enabled, it uses NPIV to migrate the guest.    If none of these options is available, it copies the data across the LAN. Using Microsoft Clustering Service with Hyper-V requires Windows 2008 Enterprise Edition. With NPIV, you can get nearly the same level of availability, but you can use Windows 2008 Standard. The advantage to Clustering is the automatic level of HA; without it, you must migrate a guest manually. Using NPIV allows for a SAN migration that is much quicker than a LAN-based migration. Virtual Disk Service provides the same capability. Setting Up NPIV with Brocade HCM and Microsoft Hyper-V 3 of 12    DATA CENTER TECHNICAL BRIEF T EST C ONFIGURATION   The test infrastructure, shown in Figure 2, included four servers:    Windows Domain Controller (DC)    Microsoft SQL Server, SCOM, and SCVMM server (referenced as the “management server”) on Windows 2008 Standard (64 bit)    Two servers with Hyper-V on Windows 2008 Enterprise Edition (64 bit) All servers had patches applied that were available on 2/26/2009, with the Hyper-V servers having additional patches as recommended in Microsoft KB articles. Installed in the Hyper-V servers were  Brocade 825 (dual ports) 8 Gbps Fibre Channel to PCIe HBAs  with firmware version 1.1.0.1 and driver version 1.1.0.1 and Brocade Host Connectivity Manager (HCM) version 1.1.0.1. Each port was connected to a Brocade 5100 Switch with Fabric OS ®  (FOS) 6.1.1d. The storage used in the testing was a Hewlett-Packard MSA 2000; components in your production environment should be chosen to meet your company’s availability requirements..

Guest Files Several files are associated with the guest in addition to the virtual disk (if you are using one):    <vmguid>.bin file  The .bin file is used to allocate enough space to store the contents of the memory for the Virtual Machine if it needs to be saved; it will be the size of memory defined for the child partition.    <vmguid>.vsv file.  The .vsv file is the saved state for devices. When a VM is rebooted, 20 MB is reserved for the .vsv. When the VM is placed into a saved state, this file can shrink or expand to 50 MB, depending on the number of devices configured for the VM.    .VHD file . The VHD file is the file that stores the disk when you use a virtual disk. Setting Up NPIV with Brocade HCM and Microsoft Hyper-V 4 of 12
