Page 8: Hyper-V Architecture
Hyper-V Architecture Microsoft® Hyper-V is a hypervisor-based virtualization technology from Microsoft that is integrated into Windows Server 2008 x64 editions of the operating system. Hyper-V allows a user to run multiple operating systems on a single physical server. To use Hyper-V in Windows Server 2008, enable the Hyper-V role on the Microsoft Windows Server 2008 server. -
Page 9: Windows Hypervisor
Windows Hypervisor The Windows Hypervisor is a thin layer of software that allows multiple operating systems to run simultaneously on a single physical server, and is the core component of Hyper-V. The Windows Hypervisor is responsible for the creation and management of partitions that allow for isolated execution environments. As shown in Figure 1, the Windows Hypervisor runs directly on top of the hardware platform, with the operating systems running on top. -
Page 10: Emulated And Synthetic Devices
Integration Components Integration components (ICs) are sets of drivers and services that enable guest operating systems to use synthetic devices, thus creating more consistent child partition performance. By default, guest operating systems only support emulated devices. Emulated devices normally require more overhead in the hypervisor to perform the emulation and do not utilize the high-speed VMBus architecture. -
Page 11: Disk Interface
Because dynamic VHDs have more overhead, best practice is to use fixed VHDs in most circumstance. For heavy application workloads such as Exchange or SQL, create multiple fixed VHDs and isolate applications files such as database and logs on their own VHDs. Pass-through Disks A Hyper-V pass-through disk is a physical disk or LU that is mapped or presented directly to the guest OS. -

I/O. Setting queue depth correctly allows the controllers on the Hitachi storage system to optimize multiple I/Os to the physical disk. This can provide significant I/O improvement and reduce response time. -

512 command data blocks ÷ 16 LUs presented through the front-end port = 32 HBA queue depth setting Basic Storage System Setup The Hitachi Adaptable Modular Storage System 2000 family has no system parameters that need to be set specifically for a Hyper-V environment. With the 2000 family’s Dynamic Load Balancing Controllers that feature... - Page 14 Dedicated VHD Deployment Figure 2 shows dedicated VHDs for the application files and the mapping within the 2000 family storage system to the mapping within the Hyper-V parent partition, and the child partition. Note that this scenario uses synthetic SCSI controller interface for the application LUs. Figure 2.
- Page 15 Shared VHD Deployment This scenario utilizes a shared VHD disk, with that single VHD disk hosting multiple child partitions. Figure 3 shows a scenario where Exchange and SQL child partitions share a VHD disk on a 2000 family storage system and SharePoint and BizTalk child partitions also share a VHD disk on the 2000 family storage system.
- Page 16 Pass-through Deployment This scenario uses pass-through disks instead of VHD disks. A dedicated VHD LU is still required to host virtual machine configuration files. Do not share this VHD LU with other child partitions on the Hyper-V host. Figure 4 shows a scenario in which virtual machine configuration files, guest OS binaries, the page file and SQL Server application libraries are placed on the VHD LU, and the application files are deployed as pass- through disks.
- Page 17 HSDs. Zoning defines which LUs a particular Hyper-V server can access. Hitachi Data Systems recommends creating an HSD group for each Hyper-V server and using the name of the Hyper-V server in the HSD for documentation purposes.
- Page 18 Key considerations: • For increased availability due to dynamic addition of LUs to the child partition, choose the direct connection configuration. • For simpler physical to virtual conversions (because reconfiguration of the iSCSI initiator and targets is not required), choose the iSCSI direct connection configuration. •...

Page 19: Storage Provisioning
Because all LUs on a particular RAID group share the performance and capacity offered by the RAID group, Hitachi Data Systems recommends dedicating RAID groups to a Hyper-V host or a group of Hyper-V hosts (for example, a Hype-V failover cluster) and not assigning LUs from the same RAID group to... -
Page 20: Hyper-V Protection Strategies
Create VHDs on the LUs as needed. • Monitor and measure the capacity and performance usage of the RAID group with Hitachi Tuning Manager software and Hitachi Performance Monitor software. Monitoring and measuring the capacity and performance usage of the RAID group results in one the following cases: •... -
Page 21: Storage Replication
Data replication and control are handled by the Hitachi Storage Cluster (HSC) software and the storage system controllers. This has little effect on the applications running in the child partition and is fully automated. -

IP networks and the 2000 family storage system using tools such as Windows Performance Monitor (PerfMon) and Hitachi Performance Monitor feature. Note that while PerfMon provides good overall I/O information about the Hyper-V parent and the guests under the Hyper-V parent, it cannot identify all possible bottlenecks in an environment. -
Page 23: Hitachi Performance Monitor Feature
Figure 8. Hitachi Performance Monitor Feature You can measure utilization rates of disk subsystem resources, such as load on disks and ports, with Hitachi Performance Monitor feature. When a problem such as slow response occurs in a host, an administrator can use Hitachi Performance Monitor feature to quickly determine if the disk subsystem is the source of the problem. - Page 24 Contact Information: + 44 (0) 1753 618000 www.hds.com / info.uk@hds.com Hitachi is a registered trademark of Hitachi, Ltd. in the United States and others countries.
