Hyper-V Key Features
Hyper-V in Windows Server 2008 R2 includes five core areas of
improvement for creating dynamic virtual data centers:
- Increased availability for virtualized data centers
- Improved management of virtualized data centers
- Increased performance and hardware support for Hyper-V virtual
machines
- Improved virtual networking performance
- Simplified method for physical and virtual computer deployments
by using .vhd files
Hyper-V as a part of Windows Server 2008 R2 (Standard,
Enterprise, and Datacenter) and of x64 editions of Windows Server
2008 (Standard, Enterprise, and Datacenter) includes the following
capabilities:
- High availability
- Server Core role
- Integrated into Server Manager
- Live Backups with VSS
- VHD tools
- Linux integration components
- VM manageability
- Improved performance
- Improved access control with AzMan
- Remote management
- Increased virtual SCSI support
- Increased memory support
Core Scenarios for Hyper-V
Server Consolidation
Businesses are under pressure to ease management and
reduce costs while retaining and enhancing competitive advantages,
such as flexibility, reliability, scalability, and security. The
fundamental use of virtualization to help consolidate many servers
on a single system while maintaining isolation helps address these
demands. One of the main benefits of server consolidation is a
lower total cost of ownership (TCO), not just from lowering
hardware requirements but also from lower power, cooling, and
management costs.
Businesses also benefit from server virtualization through
infrastructure optimization, both from an asset utilization
standpoint as well as the ability to balance workloads across
different resources. Improved flexibility of the overall
environment and the ability to freely integrate 32-bit and 64-bit
workloads in the same environment is another benefit.
Business Continuity and Disaster Recovery
Business continuity is the ability to minimize both
scheduled and unscheduled downtime. That includes time lost to
routine functions, such as maintenance and backup, as well as
unanticipated outages. Hyper-V includes powerful business
continuity features, such as live backup and quick migration,
enabling businesses to meet stringent uptime and response
metrics.
Disaster recovery is a key component of business continuity.
Natural disasters, malicious attacks, and even simple configuration
problems like software conflicts can cripple services and
applications until administrators resolve the problems and restore
any backed up data. Leveraging the clustering capabilities of
Windows Server 2008, Hyper-V now provides support for disaster
recovery (DR) within IT environments and across data centers, using
geographically dispersed clustering capabilities. Rapid and
reliable disaster and business recovery helps ensure minimal data
loss and powerful remote management capabilities.
Testing and Development
Testing and development are frequently the first business functions
to take advantage of virtualization technology. Using virtual
machines, development staffs can create and test a wide variety of
scenarios in a safe, self-contained environment that accurately
approximates the operation of physical servers and clients. Hyper-V
maximizes utilization of test hardware which can help reduce costs,
improve life cycle management, and improve test coverage. With
extensive guest OS support and checkpoint features, Hyper-V
provides a great platform for your test and development
environments.
Dynamic Data Center
Hyper-V, together with your existing system management solutions,
such as Microsoft System Center, can help you realize the dynamic
data center vision of providing self-managing dynamic systems and
operational agility. With features like automated virtual machine
reconfiguration, flexible resource control, and quick migration,
you can create a dynamic IT environment that uses virtualization to
not only respond to problems, but also to anticipate increased
demands.
