Implementing SharePoint Server 2010 on Dell vStart Solution - A Reference Architecture for a
SharePoint Server 2010 farm on vStart 100 Hyper-V Solution
21
Key considerations
Leveraging vStart virtualized infrastructure solution for deploying SharePoint Server 2010 farm
significantly reduces the time required to plan for the infrastructure and increases the time-to-value.
vStart solutions are pre-designed, pre-built, and pre-tested and architected for high availability of all
infrastructure elements and hence provides high availability of farm roles within the SharePoint 2010
farm.
In this reference architecture, dual redundancy for SQL service and DB virtual machines was achieved
by configuring SQL failover cluster among the SQL database servers and also including the database
virtual machines as a part of the Hyper-V failover cluster. This enables faster SQL service failover
time—as small as 15 seconds—using guest failover clustering of the SQL virtual machines and a SQL
virtual machine failover of approximately 60 seconds during unplanned down time. The live migration
of an active SQL virtual machine can also be done for any planned downtime of the Hyper-V nodes
without any perceived downtime of the SQL service.
The SharePoint 2010 virtualized farm in this reference architecture was validated—using the Dell
SharePoint Load Generation framework
and SharePoint collaboration usage profile—for up to 35000
users with 10% concurrency with a farm response time of 0.1 seconds and 285 requests per seconds.
The processor usage on the SharePoint WFE servers was at an optimal level (approximately 75 percent)
and 45 percent on the active database virtual machine.
NOTE: The farm performance discussed here is relative to the usage profile used in the lab testing. The
performance may differ based on the workload profile and content database size.
The SharePoint farm design in this reference architecture used only two WFE servers in NLB cluster.
However, the application server virtual machines can also be added to the NLB cluster when a higher
user load capacity is desired and/or the load on WFE servers need to be reduced.
Using SQL server service in a virtual machine is not recommended when the database load is high. This
reference architecture—by deploying SQL server as a virtual machine—may not scale beyond 4000
concurrent users or with higher SharePoint content database size.
Summary
A SharePoint 2010 farm consists of multiple servers, each provisioned with different SharePoint
components. There are several design and best practices to consider while building the infrastructure
for a SharePoint farm. These design considerations includes aspects such as high availability of all
SharePoint farm roles, service application architecture considerations, and storage and networking best
practices.
The Dell vStart virtualized infrastructure has been designed to reduce the time-to-value and enable
rapid application deployment. Leveraging this infrastructure for deploying SharePoint farm derives
several benefits. This includes rapid time-to-value for SharePoint application, high availability at all
