WHY VIRTUALIZE?
http://www.SharePointSaturday.org/LA
Why Virtualize?• Direct Server over consumption /
Utility Bills / “Greener” technology
• Less Physical space to consume • Less cost to cool multiple servers
Reduce Costs
• Reduce number of physical servers
• Get rid of legacy hardware• Dedicated specialty servers
Consolidate /
Dedicate
• Optimized use of memory/processor
• No proliferation of disk volumes• Large number of servers can run
on a single box
Optimize Investme

SHAREPOINT 2010 VIRTUALIZATION GUIDELINES
http://www.SharePointSaturday.org/LA
Virtual Host Guidelines• Dedicated hosts for SharePoint Virtual Guests
• No Software on Host OS! (Except A/V or Backup)
General
• Allocate Passthrough/RDM NICs for best perf
• Aggregate NICs at a minimum• Create dedicated NIC for Management• Create dedicated NIC for Failover
NICs
• Dedicated spindles for SharePoint• Dedicated volume for Host OS• Dedicated volume for Guest OS VHDs• Dedicated volume for Databases and
Logs
Disk
• Avoid overallocating (applies to memory as well)
• No more than 2 vCPUs for every Core• Ideally 1:1 ratio for best performance
Max 2:1 Core/vCPU
Ratio
http://www.SharePointSaturday.org/LA
SP2010 Role Virtualization
• Excellent Virtualization Candidate• Can be easily provisioned via templatesWeb
• Higher proc/mem requirements, but still good candidate
• Often paired with SP2010 Web Role• Requires 2nd Disk for Index
Search Service
App
• Higher proc/mem requirements, but still good candidate
• Low disk requirements compared to other roles
Other Service Apps
• Requires the most memory, proc, and disk IO• Be cautious when virtualizing, make sure host is
scaled• Remember, Virtualization for Virtualization’s sake is
bad

SharePoint Guest Guidelines
http://www.SharePointSaturday.org/LA
VM Guest Guidelines:SharePoint Roles• Fixed size Disk a minimum
• Pass-through (raw) disk is recommended, but not required.
• Address Disk I/O (Dedicated spindles, etc.)
Disk
• Created dedicated virtual switch for SharePoint
• Use VLAN tagging for Security• Ensure host has redundant network links• Highly consider passthrough NICs
Network
• Load balance like servers across hosts• Install Integration components on servers
(Win2008 R2 automatically does for Hyper-V)
General
http://www.SharePointSaturday.org/LA
• Passthrough/RDM strong recommendation
• If Passthrough/RDM Disk not used, scale out the server tier
• Follow best practices for tempDB, others
Disk
• Ideally Passthrough/RDM NICs• Aggregate Host NICs at a minimum• If using Virtual NICs, used a dedicated
virtual switch
Network
• Be sure your hosts have the necessary capacity, or you will have performance bottlenecks
• SQL Mirroring and Clustering now supported on virtual guests (KB 956893)

NUMA MEMORY GUIDELINES
http://www.SharePointSaturday.org/LA
NUMA Memory Limitations and Guidelines
Non-Uniform Memory Access (NUMA) Boundaries exist at the hardware level.
Virtual guests that are allocated more memory than exist within a single NUMA memory boundary have significantly impacted performance
NUMA boundaries vary by processor and motherboard vendor, but good rule of thumb to calculate boundaries is to divide the amount of memory in the system by the total number of cores. i.e. Dual Quad-core host (2x4 cores = 8 cores) with 64GB of
RAM on the host would mean NUMA boundary is 64/8 or 8GB. In this example, allocating more than 8GB for a single guest
session would result in performance drops.
http://www.SharePointSaturday.org/LA
NUMA Memory Limitations and Guidelines
Keeping NUMA boundaries in mind, this means that you will get significantly better performance provisioning two SharePoint front-ends with half the amount of RAM as a single front-end with twice as much RAM.
This applies to any virtualization platform, as the limitation is hardware specific. NUMA allocation specifics will vary by vendor, however.
Refer to MS Whitepaper on Virtualization of SharePoint (http://tinyurl.com/virtualsp) for more specifics.

VIRTUALIZATION PERFORMANCE MONITORING
http://www.SharePointSaturday.org/LA
Manually with Perfmon counters Collect data over a week minimum to
look for trends throughout the week Use to help prove performance
problems are not because of virtualization
Consider using System Center Operations Manager 2007 R2 for long-term performance analysis and threshold alerting

SHAREPOINT VIRTUALIZATION SUPPORT
http://www.SharePointSaturday.org/LA
Microsoft Support of SharePoint Virtualization
Microsoft’s official SharePoint support stance is that any SharePoint role or service is supported for hardware virtualization, including SQL Server 2005, SQL Server 2008, or SQL Server 2008 R2. There are only three requirements for virtualization that must be satisfied, these are as follows: Hardware-assisted virtualization, which is available in
processors that include a virtualization option—specifically processors with Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technology.
Hardware-enforced Data Execution Prevention (DEP) is available and enabled.
Either deployed on Microsoft Hyper-V (RTM or R2 version) or a validated third-party hypervisor that is part of the Server Virtualization Validation Program (SVVP) – KB 897615
http://www.SharePointSaturday.org/LA
What does this mean for SharePoint on Third party?
SharePoint supported on VMware ESX/ESXi, Citrix XenServer, or others in the SVVP
This only covers Hypervisor products, so excludes products such as VMware Workstation or VMWare Server
http://www.SharePointSaturday.org/LA
WINDOWS SERVER 2008 R2 HYPER-V
http://www.SharePointSaturday.org/LA

SYSTEM CENTER VIRTUAL MACHINE MANAGER 2008 R2
http://www.SharePointSaturday.org/LA
System Center Virtual Machine Manager (VMM)
Virtualization Host and Guest Management Platform
Part of the System Center Management Suite, which includes the following: System Center Operations Manager 2007 System Center Data Protection Manager 2007 System Center Configuration Manager 2007 R2 System Center Mobile Device Manager 2007 System Center Essentials 2007 System Center Capacity Planner 2007 System Center Service Manager 2010
http://www.SharePointSaturday.org/LA
System Center Virtual Machine Manager (VMM) 2008
New version out (VMM 2008 R2) VMM 2008 R2 has P2V (Physical to virtual
migration) and V2V (VMware Guest migration to Hyper-V) tools
For SharePoint, allows for creation of SharePoint template servers that can be quickly provisioned for test farms or for new farm members in production
Can manage both Hyper-V and VMware guests (though must ‘go through’ a Virtual Center server to manage VMware guests.)
Self-Service Portal allows end users and remote admins to be able to provision their own virtual machines based on templates
http://www.SharePointSaturday.org/LA
Quick SP2010 Farm Provisioning with VMM 2008 R2
1. Create new Virtual Guest (Windows Server 2008 R2)
2. Install SP2010 Binaries. Stop before running Config Wizard
3. Turn Virtual Guest into Template, modify template to allow it to be added into domain
4. Add PowerShell script to run on first login, allowing SP to be added into farm or to create new farm
Voila! 15 minute entire farm provisioning…

virtualization role) Enterprise Edition: Four virtual guests (if host is dedicated to
virtualization role) / Guests can be Std/Ent DataCenter Edition: Unlimited Number of Virtual Guests / Per

System Center Management Suite Enterprise Edition License: Gives unlimited DPM, OpsMgr, ConfigMgr, and VMM Agents for all virtual guests on the host.
Check with Microsoft for Specifics…
Virtualized Farm ArchitectureMicrosoft Virtualization Licensing Primer
http://www.SharePointSaturday.org/LA
Microsoft Virtualization Guest Licensing Model
Guests can run any combination of downlevel licenses (i.e. Datacenter host, Ent or Std edition guests)
Applies not only to OSes running virtualized with Windows Virtualization, but it also applies to 3rd party virtualization as well!
http://www.SharePointSaturday.org/LA
Session Takeaways
Understand the architecture options for SharePoint 2010
Consider Virtualization for SharePoint, but architect host and guest environments very carefully.
Best performance comes from dedicated virtual hosts, dedicated passthrough NICs, and dedicated passthrough disks and by not overcommitting resources.
KB897615 outlines MS Support for 3rd Party Virtualization such as VMware and XenServer…
Windows Server 2008 R2 Hyper-V technology gives high performance and is a very cost competitive option
MS Licensing has new virtualization support, and Datacenter edition will provide for unlimited guests under a single host.
