BizTalk Virtualization Licensing
•
•
•
•
License required for each physical
processor
License for each virtual processor in each
virtual operating system
Exception: BizTalk Enterprise Edition
− License for the number of physical processors
in the server
− Enables unlimited virtual processors

Hyper-V Supportability Overview
•
•
•
•
BizTalk Server 2004/2006/2006 R2 fully
supported
− http://support.microsoft.com/kb/842301
SQL Server 2005 provides commercially
reasonable support
BizTalk Server 2009 will provide full HyperV support
SQL Server 2008 will provide full Hyper-V
support
Hyper-V Performance Overview
•
•
•
•
Our results indicate that performance is
good
Virtual processors scale well
Storage design should be considered
carefully
Hyper-V provides more pieces to monitor:
− Performance counters
− xPerf/ETW should be used for performance
analysis

~80% of the throughput relative to when the
virtual BizTalk Server and SQL Server
machines were hosted on separate
hardware
~10% overhead of running both groups
simultaneously
Networking performs well
Running two groups only placed ~40% CPU
load on the physical server
Adding additional virtual machines
increases load on Hyper-Visor

Processor Lessons Learned
•
•
% Processor Time on the Host does not
measure physical processors
For high processor usage:
− Most Efficient: 1:1 Logical to Virtual
Processors
− Better Performing, Less Efficient: 2:1 Logical
to Virtual Mapping of Processors

Disk Lessons Learned
•
Use PassThrough disks for high disk I/O:
−
−
−
−
BizTalk MessageBox Database
BizTalk Tracking Database
BizTalk File Adapter
%temp directory if BizTalk is streaming large
files
Memory Lessons Learned
•
•
•
Virtual machines require non-paged
memory (physical memory)
Ensure you have enough physical memory
on both the host and guest computers
Use Traditional Counters:
−
−
−
−
<RootPartition>\Memory\Available Mbytes
<Guest>\Memory\Available Mbytes
<RootPartition>\Memory\Pages/sec
<Guest>\Memory\Pages/sec
Network Lessons Learned
•
•
For high network I/O:
− Use a 1:1 mapping of physical to virtual
network adapters
For measuring network adapters use:
− <RootPartition>\Network Interface
− Bytes Total Per Second
− Output Queue Length
− <RootPartition>\Hyper-V Virtual Network
Adapter
− Bytes Per Second
− <RootPartition>\Hyper-V Virtual Switch

BizTalk Hyper-V Summary
•
•
•
•
Fundamental BizTalk design decisions have not
changed
Performance or efficiency driven
− To maximize performance use Fixed VHD not Dynamic
or Differencing disks
− >1:1 Virtual:Logical processors can degrade
performance
Pass-through for High I/O
− BizTalk – file receive locations, %temp folder
− SQL Server – System and User Databases
