Why Virtualize?
![Page 5: SharePoint 2010's Virtual Reality - SPC2C](https://reader037.vdocuments.net/reader037/viewer/2022110115/5498da81b479596b078b4592/html5/thumbnails/5.jpg)
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 Investment

SharePoint 2010 Virtualization Guidelines
![Page 7: SharePoint 2010's Virtual Reality - SPC2C](https://reader037.vdocuments.net/reader037/viewer/2022110115/5498da81b479596b078b4592/html5/thumbnails/7.jpg)
Virtual Host Guidelines• Dedicated hosts for SharePoint Virtual Guests
• No Software on Host OS! (Except A/V or Backup)
General
• Allocate Passthrough/RDM NIC 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

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
![Page 10: SharePoint 2010's Virtual Reality - SPC2C](https://reader037.vdocuments.net/reader037/viewer/2022110115/5498da81b479596b078b4592/html5/thumbnails/10.jpg)
• 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
switchNetwork
• 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
![Page 19: SharePoint 2010's Virtual Reality - SPC2C](https://reader037.vdocuments.net/reader037/viewer/2022110115/5498da81b479596b078b4592/html5/thumbnails/19.jpg)
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.
![Page 20: SharePoint 2010's Virtual Reality - SPC2C](https://reader037.vdocuments.net/reader037/viewer/2022110115/5498da81b479596b078b4592/html5/thumbnails/20.jpg)
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
![Page 24: SharePoint 2010's Virtual Reality - SPC2C](https://reader037.vdocuments.net/reader037/viewer/2022110115/5498da81b479596b078b4592/html5/thumbnails/24.jpg)
• 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
![Page 27: SharePoint 2010's Virtual Reality - SPC2C](https://reader037.vdocuments.net/reader037/viewer/2022110115/5498da81b479596b078b4592/html5/thumbnails/27.jpg)
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
![Page 28: SharePoint 2010's Virtual Reality - SPC2C](https://reader037.vdocuments.net/reader037/viewer/2022110115/5498da81b479596b078b4592/html5/thumbnails/28.jpg)
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

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 R2● System Center Data Protection Manager 2007● System Center Configuration Manager 2007 R2● System Center Mobile Device Manager 2007● System Center Essentials 2007● System Center Service Manager 2010

System Center Virtual Machine Manager (VMM) 2008 R2
• 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

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…

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!

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.
