6. Q1:- Physical or Virtual?
Running application in physical or virtual?
or

7. Q2:-Virtualize or Not Virtualize ?
Suitable candidate

 Low processor
 Low Memory VM 1- VM 3- 4 GB
14 GB VM 2- 4 GB
Unsuitable candidate VS VM 1- 2 GB
High processor

Physical Server (16 GB RAM)

8. Understand Your Application #1
Don’t virtualize everything !
Not ALL Applications are Inventory
suitable to be Virtualized
External Hardware (USB,
dongle, etc)
High Resource & Utilization Reporting Assessment
Check Microsoft Support
Policy
Use Microsoft Assessment
and Planning Toolkit (MAP)
6.0

12. Hardware Selection #2
CPU Memory Hard Disk Network
 Hardware  More  High RPM  More NIC
assisted RAM the (15K rpm) the better
Virtualization better  SAS  1Gbps/10Gb
 Hardware DEP  RAID 10 ps
 X64 Bit
 SLAT

13. Shared Storage Selection
NAS DAS iSCSI SAN FC SAN
 Not  Small  Small /  High
Supported scale Medium Performance
 2–4 scale  Expensive
nodes  Cheaper
than FC
SAN

14. Securable
Determine processor suitability for
virtualization

16. Stand-Alone or Cluster Hyper-V #3
Up to you to decide. But recommended, Cluster
Hyper-V
Stand alone

Cluster Hyper-V

17. Deployment

18. Host Setup Consideration
RAID ?
Antivirus?
Windows ?
Teaming / MPIO?

20. Use Server Core #4
Reduce surface attack, less patch
Not Recommended Recommended

21. Core Configurator
GUI to manage in
Server Core.
Mainly on system
settings on
Windows.

23. Avoid using the Root Partition #5
Avoid running services on the root partition
(host machine)
X
Just Hyper-V Roles…
DHCP
DNS
IIS
Directory
Services
…

24. Leave Memory for the Root #6
Leave at *least* 512MBs of RAM to the
root partition. 2GB or more
recommended. DM: 4 GB
VM 4- 4 GB
DM: 4 GB
VM 3- 4 GB
Hyper-V (0 GB)
Physical Server (16 GB RAM)
Hyper-V Host 1

25. Different Types of Virtual Machine Disk

26. Use Fixed Disk- Virtual Machine #7
Good: Dynamic and Fixed Size VHDs perform about
the same now.
Still Best: Pass-Through is best for performance.
The following charts are from WS08 R2:
Lower is better Higher is better

27. Antivirus
Configure exclusion

Virtual Machine VHD Directory
Snapshot Directory
VMMS.EXE
VMWP.EXE
Cluster Storage Volume (CSV)

28. Management

29. Close the Window on Managers #8
Hyper-V Manager, VMConnect, Wallpaper & screen Saver
sessions consume resources.
Close or minimize the Hyper-V Manager & VM Connect.
No Wallpaper & Screen Saver on Virtual Machine
Hyper-V Manager VMConnect Wallpaper/ScreenSaver

30. Disable Removable Media #9
Disable the removable media drives (floppy,
optical drive, etc.) when not in use.
Removable media is polled periodically.

31. Monitor VM CPU MEM
