vStart 1000m for Enterprise Virtualization using Hyper-V – Reference Architecture
Dell Inc. 9
with redundant network interface controllers (NICs) and redundant switches. NIC teaming for LAN and
MPIO for SAN are used to provide failover across the redundant network interfaces.
For FC storage, redundancy is achieved with multiple HBA ports, FC switches, and storage controllers.
For network traffic, NIC ports are teamed in such a way that they avoid any single point of failure.
Hyper-V High Availability (HA) is provided by Windows Server 2008 R2 Failover Clustering. The solution
also includes redundant power supplies connected to separate PDUs.
4.3 Flexible configurations
vStart 1000m is pre-configured to suit most customer needs for a virtualized infrastructure. The
solution also supports additional options, such as configuring racks, server processors, server memory,
and storage, based on customer needs.
4.4 Racked, Cabled and Ready to be deployed
vStart is available partially racked, cabled, and delivered to the customer site ready for deployment.
Components are configured and racked to optimize airflow and thermals. Based on customer needs,
different rack sizes and configurations are available to support various datacenter requirements.
5 Prerequisites and Datacenter Planning
Power, Cooling, and Weight Considerations: vStart 1000m solution is configured with Power
Distribution Units (PDUs) to meet the power requirements of the components, as well as regional
constraints. Power consumed, cooling required, and information regarding rack weight are provided to
enable customers to plan appropriate power and cooling for the solution.
To support the architecture, the following components are required to be present in the customer
environment:
· An existing 10 Gb Ethernet infrastructure with which to integrate. In addition, it is assumed
that there is a 1 Gb Ethernet network infrastructure in place to support the management
network.
· Additional components, such as Force10 network cables and transceivers, are needed to uplink
the solution to the customer network. The components to be added will depend on customer
networking and uplink requirements.
· Active Directory® (AD) Domain Services (AD DS) – An AD DS domain must be available on the
network. The Hyper-V hosts will be joined to an existing or new domain. Cluster Services also
require AD DS. Consult with your Dell Sales and Services representatives for more details.
· Domain Name Server (DNS) – DNS must be available on the management network.
· Database to support SC 2012 VMM - For a list of supported databases refer to: Requirements
for System Center 2012 - Virtual Machine Manager
o If IT Administrators wish to install VMM on the Dell PowerEdge R620 Management Server
or as a VM, then a route must exist between the management server (physical or as a
VM) and the database used.
o The database is assumed to have maintenance and backup configured as per the
business needs of the customer.
