5.4 Hyper-V Role and Failover Clustering Design
5.4.1 Roles and Features
The Hyper-V role is required on the Windows Server 2008 R2 Datacenter host. The role enables features
such as creation, starting, and stopping of VM.
Failover Clustering is a feature that, when combined with the Hyper-V role provides fault tolerance at
the server level and enables features like Live Migration and VM failover.
More information on setting up Failover Clusters for Hyper-V can be found on Microsoft TechNet in
Hyper-V: Using Hyper-V and Failover Clustering available at http://technet.microsoft.com/en-
us/library/cc732181(WS.10).aspx .
Cluster Shared Volumes (CSV) is implemented on the Hyper-V cluster to allow multiple virtual machines
to utilize the same volume and migrate to any host in the cluster. The Live Migration feature of
Windows Server 2008 R2 allows movement of a virtual machine from one host to another without
perceivable downtime. For more information on configuring CSV and the network for live migration see
Hyper-V: Using Live Migration with Cluster Shared Volumes in Windows Server 2008 R2 available at:

5.5 Management Architecture
The management architecture of the vStart configurations includes hardware and software components
that will manage all components of the vStart architecture. They can be found on the R620 server or on
VMs running on the R620.
5.5.1 Management on the LAN
The management traffic on the LAN includes:
 Out–of-band server management through the iDRAC7 Enterprise
 Server management through Dell OpenManage Server Administrator
 Hyper-V and Cluster Manager
 LAN switch management through CLI or web browser
 EqualLogic array management through CLI or web browser
 EqualLogic array monitoring with SAN HQ
 Virtualization Management with SCVMM
Server Out-of-Band Management: The PowerEdge R720 servers and the PowerEdge R620 can be
managed directly by connecting to the iDRAC7 SSH or web interface. In addition, the iDRAC7 supports
remote KVM through a virtual console.
Dell OpenManage Server Administrator (OMSA): OMSA provides server hardware data to the host.
Information presented includes fan speeds, operating temperature, and various other heath monitors.
For more information about OMSA, refer to the Dell TechCenter at
http://www.delltechcenter.com/page/OpenManage+Server+Administrator+-+OMSA .
Hyper-V Cluster Management: Management of the Hyper-V hosts may optionally be performed
directly with SCVMM 2008 R2, but can also be performed by connecting to each server through the
