SharePoint 2010 Virtualization Guidelines and Models
NUMA Memory Limitations and Guidelines<br /><ul><li>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.</li></li></ul><li>NUMA Memory Limitations and Guidelines<br /><ul><li>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.</li></li></ul><li>NUMA Example: 2x Quad Core, 64GB RAM<br />Proc 1<br />Proc 2<br />
Microsoft Support of SharePoint Virtualization<br /><ul><li>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</li></li></ul><li>What does this mean for SharePoint on Third party?<br /><ul><li>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
Less need to reproduce problems in physical environment</li></li></ul><li>Windows Server 2008 R2 Hyper-V<br />
System Center Service Manager 2010</li></li></ul><li>System Center Virtual Machine Manager (VMM) 2008 R2<br /><ul><li>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
PowerShell support allows for scripted provisioning of SharePoint 2010 or other servers into a farm</li></li></ul><li>Quick SP2010 Farm Provisioning with VMM 2008 R2<br />Create new Virtual Guest (Windows Server 2008 R2)<br />Install SP2010 Binaries. Stop before running Config Wizard<br />Turn Virtual Guest into Template, modify template to allow it to be added into domain<br />Add PowerShell script to run on first login, allowing SP to be added into farm or to create new farm<br />Voila! 15 minute entire farm provisioning…<br />
System Center Management Suite Standard Edition License: Gives DPM, OpsMgr, ConfigMgr, and VMM Agents for 1 server.
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…</li></li></ul><li>Microsoft Virtualization Guest Licensing Model<br /><ul><li>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!</li></li></ul><li>Session Takeaways<br /><ul><li>Consider Virtualization for SharePoint, but architect host and guest environments very carefully.
Best performance comes from dedicated virtual hosts, dedicated passthrough NICs (RDM), and dedicated passthrough disks (RDM) and by not overcommitting resources.
Monitor performance metrics to look for bottlenecks
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.</li></li></ul><li>For More Information<br />SharePoint 2010 Unleashed (SAMS Publishing) (http://www.samspublishing.com)<br />Windows Server 2008 R2 Unleashed and/or Hyper-V Unleashed (http://www.samspublishing.com)<br />Microsoft ‘Virtualizing SharePoint Infrastructure’ Whitepaper (2007) (http://tinyurl.com/virtualsp) <br />Microsoft ‘Virtualizing SQL Server’ Whitepaper (http://tinyyurl.com/virtualsql)<br />Microsoft’s Guidance on Virtualization Monitoring (2007) (Brian Wilson, MCS) http://tinyurl.com/monitorsp<br />Contact us at CCO.com<br />
