12. Placement - Host Ratings Calculation
Microsoft Virtualization Deployment Summit
11/12/2018 3:42 AM
Placement - Host Ratings Calculation
Let us see how the rating calculation occurs,
The purple color indicates the resources that are already consumed by the host machine
The blue color indicates the resources that are required by the new Virtual Machine
There is a set of resources being kept as a buffer for the host machine and the resulting free resources are then converted into a number
and that number is then compared against the rating of importance that are set within the algorithm configurations when you ran the intelligent placement
Based on this calculation the final host numerical rating is given and that is the star rating which is presented to the administrator
As you change the slider or change the algorithm the end results of the star rating will change based on the numbers that you get from the calculation
Host Rating = (Free CPU * CPU Weight) + (Free Memory * Memory Weight) +
(Free Disk * Disk Weight) + (Free Network * Network Weight)
Host Rating equal 0 if any of the thresholds have been violated.

13. Demo Intelligent Placement
Let us have a quick demo on how the Intelligent placement helps administrators to make a easy decision for placing a virtual machine.

14. Performance And Resource Optimization (PRO)

15. Performance And Resource Optimization (PRO)
Workload and application aware resource optimization
Extensible through the Operations Manager 2007 MP framework
Create policies that VMM acts upon tips automatically or manually
Minimize downtime and accelerating time to resolution
Enables partners to deliver value add to our mutual customers

16. Performance And Resource Optimization (PRO)

17. Performance And Resource Optimization

18. Unified Management

19. Unified Management Powerful cross-platform virtualization management
Support for VMware VI3
Single management console across Virtual Server, Hyper-V and VI3
Manage and integrate multiple VMware environments
Streamline and automate all task using VMM
You decide where workloads should run across your environment
Co-exists with Virtual Center
Updates made in Virtual Center reflected in VMM in real time and vice versa

20. P2P and V2V Conversion
P2V is a core feature of Virtual Machine Manager, no additional costs per conversion
Wizard based experience, easy to use
Reconfigure storage, memory, CPU, etc
Efficient disk copy
Reserves network settings and MAC addresses
Automatable through PowerShell
Supported Platforms
Live (using VSS - Win XP, Win 2003, Win Vista and Win 2008)
Offline - Windows 2000 server
P2V online requires no reboot | P2V offline uses WinPE
V2V converts(offline) either a VMware disk or the whole VM to the Microsoft VHD\VM representation

21. P2V and V2V Migration
Demo

22. Cluster Management

23. Cluster Management – VMM 2008
Easy management of Hyper-V host clusters
Add entire Hyper-V host cluster in a single step
Automatic detection of node additions/removals
Support VMware host clusters
Cluster reserve
Specify the number of node failures to sustain while keeping all HA VMs running
Intelligent Placement ensures that new HA VMs will not over commit the cluster
Node failures automatically trigger over commit re-calculation

24. Configuring A VM To Be Highly Available

25. Virtualization And High Availability
Traditional Non- Virtualized Environment
Downtime is bad, but affects only one workload
Virtualized Environment
Value of the physical server goes up
Downtime is far worse because multiple workloads are affected
Virtualization and High-Availability Go Hand in Hand

26. 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

27. Quick Migration Fundamentals – Planned Downtime
1. Save state
Save entire virtual machine state
2. Move virtual machine
Move storage connectivity from origin to destination host
3. Restore state and Run
Restore virtual machine and run
VHDs
Shared Storage
Network Connectivity

28. Quick Migration Planned Downtime

29. Quick Migration Unplanned Downtime

31. Quick Migration Storage Considerations (1/2)
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

32. Quick Migration Storage Considerations (2/2)
SAN/ISCSI
Leverage MPIO solutions for path availability and I/O throughput
Leverage VM provisioning via GUID ID instead of drive letter
\\?\<GUID>\
Deploy KB cluster update to support:
Support for MountPoints or Volumes with no Drive Letter
GUID Volume Path Copy
Allow more than one virtual machine in a "Services or Applications" group

34. SCVMM 2008 Deployment Topology

35. Stand Alone Topology Single Server No SAN Used to
Segregate resources on a server
Test and Develop Solutions
As a temporary solution in a migration
Single Windows Server 2008 running all the SCVMM components such as SQL DB, IIS Web services and Library server
There is no Separate SAN, all the VMs are running in its own host
Typically this approach would be useful in the situations where
You would need to segregate resources on a server
Testing and Development
Temporary solution during the migration

36. Corporate Topology Library Server Guest VMs Guest VMs
Windows® PowerShell
Administrator Console
Library Server
Web-based Delegated Provisioning UI
Moving to next deployment approach – corporate Topology is a centralized management topology where organizations wanted to host and manage their virtual infrastructure at the central location
In this approach, you would essentially distribute the various components into individual servers in the same LAN
To obtain the high availability and performance you would typically configure host clustering and SAN storage

37. Enterprise Topology London Singapore External Network (DMZ)

Web-based Delegated Provisioning UI
External Network (DMZ)
London
Singapore
The 3rd type deployment topology is the Enterprise topology.
Where organizations wanted to host the Virtual infrastructure resources spread across their enterprise network and manage them from a central location.
Let me take a small design example for explaining this topology.
Assuming, XYZ company’s corporate office is based in India and 2 of its branch offices are based out in London and Singapore.
And there are multiple satellite offices spread across the globe with small user base(2/3 users) and they would be connecting through internet.
As a first step toward the deployment,
I will install a remote Library server and virtual machine hosts at the branch office locations both in London and Singapore.
Since the remote users are spread across the globe and they would be connecting to the corporate office through internet, I will host separate Library server and virtual machine hosts in the De-Militarized Zone for the remote user to connect and access the corporate resources
I would also configure port 80 and 443 on the firewall for the communication to take place between the SCVMM server, remote library and the virtual machines hosts
