  6. 6. 64-Bit processors with hardware virtualization extensions enabled Intel-VT AMD-V Hardware enabled Data Execution Prevention (DEP) required AMD (NX no execute bit) Intel (XD execute disable) RAM Parent Partition 1GB Each Guest + ~21MB overhead Disk Parent Partition Space to store VHDs Space to store VSS snapshots Space to store VM snapshots Network 1 NIC for parent partition management 1+ NICs for Virtual Networks Guest usage 1 NIC for iSCSI (optional)
  7. 7. Choosing the building blocks Build a balanced system Best Practices Windows Server 2008 x64 Edition EE/DTC Server Core Installation Quad processor/Quad Core (16/24 cores) AMD-V or Intel VT Memory 2 GB per core minimum (32 GB) 4 GB per core recommended (64 GB) Storage 4 Gb Fibre Channel 1/10 Gb Iscsi Networking 1 Gb/E NIC (onboard) for VM management/cluster heartbeat/migration 1 quad-port Gb/E PCI-E for VMs 7
  8. 8. Windows Server frequently deployed for a single role Must deploy and service the entire OS in earlier Windows Server releases Server Core a new minimal installation option Provides essential server functionality Command Line Interface only, no GUI Shell Benefits Fundamentally improves availability Less code results in fewer patches and reduced servicing burden Low surface area server for targeted roles More secure and reliable with less management 8
  9. 9. 9
  10. 10. Hyper-V Storage Best Practices Performance wise from fastest to slowest… Fixed Disk VHDs/Pass Through Disks Slight performance difference Dynamically Expanding VHDs Grow as needed Do not use for production workloads Pass Through Disks Pro: VM writes directly to a disk/LUN without encapsulation in a VHD Cons: You can’t use VM snapshots Dedicating a disk to a vm 10
  11. 11. Hyper-V Storage Best Practices Leverage MPIO solutions to provide SAN path and bandwidth advantages Use Pass thru disks for I/O intensive workloads Database workloads OLTP/DSS File Servers Leverage ISCSI on the Host (Best Performance) Leverage TOE and offload cards Use ISCSI in the guest for guest clusters 11

  19. 19. Microsoft Hyper-V Quick Migration Provides solutions for both planned and unplanned downtime Planned downtime Quickly move virtualized workloads to service underlying hardware More common than unplanned Unplanned downtime Automatic failover to other nodes (hardware or power failure) Not as common and more difficult 19
  20. 20. Quick Migration Fundamentals – Planned Downtime VHDs 1. Save state Shared Storage a) Save entire virtual machine state 2. Move virtual machine a) Move storage connectivity from origin to destination host 3. Restore state and Run Network Connectivity a) Restore virtual machine and run 20
  21. 21. Quick Migration Storage Best Practices Pass-through Disks in a cluster Provides enhanced I/O performance Requires VM configuration file to be stored separate from the virtual machine file Create file share on the cluster and store VM configuration files for virtual machines that use pass-thru. VHD Based One LUN per VM best practice Ability to provision more then one VM per LUN but all failover as a unit 3rd part solutions offer the ability to provision a LUN with multiple virtual machines with granular failover 21
  22. 22. Quick Migration Storage Best Practices SAN/iSCSI Leverage MPIO solutions for path availability and I/O throughput Leverage VM provisioning via GUID ID instead of drive letter ?<GUID> Use Mountvol.exe to find GUID of provisioned LUN 22
  23. 23. 23
  24. 24. Ensure your backup solution supports VSS Support for the VSS writer in Hyper V specifically Virtual Machine Backup Best practices Leverage the Hyper V VSS writer to take online snapshots of virtual machines System Center Data Protection Manager Will provide Hyper V VSS snapshots Ability to quickly recover virtual machines Replicate snapshots to backup location for DR 24
  25. 25. 25
  26. 26. Performance Things to Understand Guest OS processors/cores are not bound (affinitized) to physical processsors/cores Physical Memory Must match the Combined Memory of All of the Guest Computers 2GB for parent partition + memory of VM +21MB The parent partition is a Virtual Machine Only run Ecosystem applications (backup, Antivirus) Measure Hyper V and Virtual machine performance using new Hyper Performance counters 29 new Hypervisor related performance counters 26
  27. 27. Measuring Processor Usage Measuring the physical host computer’s (Root Partition) Processor Capacity Hyper-V Hypervisor Logical Processor(*)% Total Run Time: The percentage of time spent by the processor in guest and hypervisor code. Measuring Guest Computer Processor Utilization HyperVisor Hyper-V Logical Processors(*)% Guest Run Time: 27
  28. 28. Measure Memory usage Measuring Available Memory on the Hyper-V Host Computer: MemoryAvailable MBytes: Available MBytes is the amount of physical memory available to processes running on the computer, in Megabytes. Same for measuring memory usage in the Virtual machine 28

  31. 31. VMM 2008 Requirements VMM 2008 Server requires Windows Server 2008 x64 for installation PowerShell feature should be added before install VMM 2008 Console will install on Windows Server 2003, Windows Vista, and Windows Server 2008 x86/x64 Non-Windows Server 2008 installations will require local installation of PowerShell 1.0 VMM 2008 Agent install on Windows Server 2003/2008. Windows Server 2008 installs require WinRM locally 31
  32. 32. VMM 2008 Installation VMM 2008 Server requires requires Active Directory for security Can manage non-AD computers, but needs AD for installation Each VMM 2008 component can be separate servers or on a single server (demo/test) VMM 2008 can be run inside a VM Just be aware of the chicken & the egg issue (understand you will need Server Manager to start the VMM VM) 32
  33. 33. VMM 2008 Scalability Support 400 hosts 8000 virtual machines per VMM Server. Best practice VMM server per datacenter Split host management by location Create library servers close to hosts In branch offices load the library server on the VM host Assign to separate spindles for I/O Replication of library servers VMM does not provide a built in replication mechanism Leverage DFS-R 3rd party replication tools (Doubletake) 33
  34. 34. VMM 2008 Overview 34
  35. 35. Host and Cluster Configuration Remote enable the Hyper-V role or Virtual Server installation Hyper-V can be remotely enabled rather than using Server Manager Virtual Server can be installed on Windows Server 2003 hosts, but WinRM needs to be installed first on the host Easy management of Hyper-V host clusters Add entire Hyper-V host cluster in a single step Cluster needs to be created outside of VMM Automatic detection of node additions/removals Management of Windows Server 2008 Failover clusters for Hyper-V Specify number of node failures you want to sustain but still have all your HA VMs running Intelligent Placement ensures that new HA VM creation will not overcommit the cluster Node failures automatically trigger overcommit re-calculation 35
  36. 36. Placement and Cluster Reserve Cluster reserve = 1 node Can the cluster sustain 1 node failure? YES Place the VM Clustered Host 1 Clustered Host 2 Clustered Host 3 36
  37. 37. Delegation and Self Service Administrators control access through policies which designate capabilities Delegated Administrators Manage a scoped environment using main UI Self service user Web user interface Manage their own VMs Quota to limit VMs Scripting through PowerShell 37
  38. 38. Understanding User Roles Membership Membership Determines which users are part of a particular user role Members may be individual users or groups Members may be in multiple user roles including user Profile roles based on different profiles Profile determines Scope Which actions are permitted Which user interface is accessible How the scope is defined User Role Scope determines Which objects a user may take actions on 38
  39. 39. Built-in Profiles Administrators Full access to all actions Full access to all objects Can use the Admin console or PowerShell interface Delegated Administrators Full access to most actions Scope can be limited by host groups and Library servers Can use the Admin console or PowerShell interface Self-Service Users Limited access to a subset of actions Scope can be limited by host groups and Library share Can use the Self-Service Portal or PowerShell interface 39
  40. 40. Customizing Scopes Administrators No scope customization available, Administrators have access to all objects Delegated Administrators Can be limited to one or more host groups including all child objects Can be limited to one or more Library servers including all child objects Self-Service Users Can be limited to a single host group where new virtual machines may be created Can be limited to a single Library share where new virtual machines can be stored Can be limited to specific templates to use for new virtual machines 40
