“By the time we hit our fifth virtual machine on a
host, we’ve usually paid for the host. Long term,
we will be able to reduce our total data center
holdings by 75 percent.”
Robert McSkinsky, Senior Systems Administrator,
Dartmouth-Hitchcock Medical Center
“We can no longer tolerate service interruptions.
With virtualization, we are creating a redundant
data center in Normandy to ensure business
continuity”
Amaury Pitrou, Projects Architecture,
Desktops and Mobility Director Bouygues Constructions
“Building a physical server took almost four
hours before virtualization. Hyper-V™ has
helped decrease this time to 20 minutes.”

Microsoft Business Server Applications
Deployment Scenarios – SharePoint
Understanding the Environment for
Virtualization – SharePoint Farm
What is a SharePoint® Farm?
A collection of one or more SharePoint Servers
and SQL Servers® providing a set of basic
SharePoint services bound together by a single
configuration database in SQL Server
Key Components:
• Web Front End (WFE) Servers:
o Windows® SharePoint Services
o Web Application Service
• Application Servers:
o Office SharePoint Server Search Service
(Index or Query)
o Document Conversion Launcher Service
o Document Conversion Load Balancer Service
o Excel Calculation Services
• SQL Server
19
SharePoint Key Roles and
Virtualization Considerations
Role
Virtualization
Decision
Considerations and Requirements
Ideal
• Easily provision additional servers for load balancing and fault
tolerance
Query Role
Process Search Queries
Ideal
• For large indexes, use physical volume over dynamic expanding
VHD
• Requires propagated copy of local index
Application Role
Excel Forms Services
Ideal
• Provision more servers as resource requirements for individual
applications increase
Web Role
Render Content
Index Role
Crawl Index
Database Role
Consider
Consider
• Environments where significant amount of content is not crawled
• Requires enough drive space to store the index corpus
• Environments with lower resource usage requirements
• Implement SQL Server® alias for the farm required

Best Practices for Configuring
SharePoint with Hyper-V
Best Practices and Recommendations
CPU
• Configure a 1-to-1 mapping of virtual processor to logical processors for best performance
• Be aware of “CPU bound” issues
Memory
• Ensure enough memory is allocated to each virtual machine
Disk
• Be aware of underlying disk read write contention between different virtual machines to their virtual
hard disks
• Ensure SAN is configured correctly
Network
• Use VLAN tagging for security
• Associate SharePoint® virtual machines to the same virtual switch
Others
• Ensure that integration components are installed on the virtual machine
• Do not use other host roles (use server core)
• Avoid single point of failure: load balance your virtual machines across hosts and cluster virtual machines

Microsoft Server Applications
Deployment Scenarios – SQL Server
SQL Server Consolidation with Virtualization
CPU utilization
Scenario Description:
• Reduce servers by consolidating virtualized
SQL Server® instances on fewer servers
File Server
• Start with departmental applications with low
server utilization
Applications Server
CRM Applications
• Deploy mission critical apps – evaluate case-bycase and determine if Service Level Agreement
(SLA) is met after virtualization
Web Server
SQL Server + Print Server
Solution Benefits:
• Help realize a higher ROI and lower TCO by
reducing:
o Hardware costs
o Energy costs
o Data center space
o Management overheads
• SQL Server Enterprise Edition offers unlimited
virtualized SQL Server instances if licensed for
all processors on physical server, therefore
potentially reducing licensing costs
• Fewer licenses due to greater licensing
mobility across servers in a farm
• Centralize data services on fewer servers

Virtualization for BI Infrastructure
High Availability with Live Migration
Remote Site Consolidation with DB
Mirroring
High Availability with Guest Clustering
Using iSCSI
Optimizing for SQL Server
Running SQL Server workloads within Hyper-V guest VM’s is a viable
option for production environment
Assuming limitations of Guest VM meet requirements of the workload.
Hyper-V guest VMs are limited to a maximum of 4 virtual CPU’s (limit of
2 virtual CPU’s on Windows 2003 guest VMs)
When compared against native the same throughput can be
achieved within a guest VM at a cost of slightly increased CPU
utilization
Assuming comparable hardware resources
Proper hardware sizing is critical to SQL Server performance
Ensure that cumulative physical CPU resources on a server are adequate
to meet the needs the guest VMs
Test/Monitor your workloads
Important to scale the performance to the total workload required of
each VM
Don’t migrate 20 physical servers with 40 spindles each to a Hyper-V host
with 10 spindles

Virtualization for BI Infrastructure
Scenario Description:
• Business Intelligence (BI) components with lower
resource requirements such as Data Mart (DM), OLAP
Cube, Reporting Servers are good candidates for scale
out and ideal for virtualization
• Operational Data Store (ODS), Data Warehouse (DW),
SQL Server® Integration Services could be physical or
virtual depending on scale up requirements
Virtualization Benefits:
• Increase agility by rapidly provisioning and
scaling-out BI components on demand
• Reduce the number of physical servers, save
on power and space
• If virtual, put SSIS and Data Warehouse on the same

High Availability with Live Migration
Scenario Description:
• Manage high availability with multipathing and live
migration for planned downtime situations, such as
hardware and software maintenance
• Failover individual virtual machines (VMs) to other
hosts within a cluster by using Cluster Shared
Volume (in Windows Server® 2008 R2)
• Use Microsoft ® System Center Virtual Machine
Manager for migrations. System Center VMM can
perform host compatibility checks before migrations
and manage multiple Live Migrations with queues.
• Nodes in cluster can be active-active
• Ensure there is enough CPU capacity for the failover
nodes in cluster
Virtualization Benefits:
• No loss of service during failover with live
migration. Migration is completely transparent to
the user
• Improve availability with less complexity
• Better server utilization due to consolidation

Database Mirroring. Automatically, failover
from primary to standby using witness.
• Consolidate mirrored database servers on
standby site with virtualization
• Use mirrored databases with database
snapshots for reporting
• Ensure there is enough CPU capacity at the
standby site to provide acceptable SLA upon
failover

HA with Guest Clustering Using iSCSI
Scenario Description:
• Improve high availability with a combination of
guest clustering and host clustering
• Only iSCSI is supported for guest clustering
• iSCSI Initiator runs within the VM allowing storage
to be fully visible to the VM
• Storage is fully visible to the guest cluster and
enables high-availability of services and applications
in the virtual layer
• Support the use of multiple redundant paths using
Microsoft Multipath IO (MPIO) or MCS (multiple
connections per session) from within the VM

Recommendations for Configuring SQL
Server with Hyper-V
Best Practices for SQL Server® with Hyper-V™
• Guest virtual machines limited to 4 CPU cores
• Configure a 1-to-1 mapping of virtual processor to logical processors for
best performance
• Network intensive applications should be tested for acceptable SLAs
• Use multipathing on host or within the VM to ensure maximum throughput
and high availability for VM workloads
• Utilize either pass-through disk or fixed-size VHD for guest virtual machines
Pass-through disk configuration provides the best I/O performance and
predictability
o Pass-through disks allow movement of data by remapping disks vs. copy
overhead on network infrastructure
o Virtual Machines using VHDs are easier to move around than pass-through disks
o
• Storage size should be considered with workload and response time
requirements
• Avoid using emulated devices. Instead, ensure integration components are
installed and synthetic devices are being used.
