The following are best practices from this chapter:
- Consolidate physical servers down to virtual guest sessions to decrease the number of physical servers in an organization, and thus ultimately lower electrical costs, server management costs, and rack-space costs associated with sprawling physical server systems.
- Although server consolidation will decrease the number of servers in the environment, take the opportunity to repurpose servers and implement high-availability and disaster-recovery strategies within the environment.
- Consider using the native high-availability and disaster-recovery technologies built in to applications (such as Exchange 2007 Cluster Continuous Replication and SQL 2005 Mirror) to establish reliable application servers in a networking environment.
- Use the built-in virtual switch technology in Hyper-V to segment guest servers and associate segments to specific network adapters on the host server for better internetworking communications.
- Dedicate core processors to virtual guest sessions to guarantee processing performance to virtual sessions that require high processing capabilities.
- Consider using Windows 2008 Server Core for the basis of the Hyper-V host server to minimize the attack surface of a host server by removing the GUI from the host system.
- Install the guest integration support tools after installing the guest operating system to take advantage of optimized drivers and session administration functions.
- Use the System Center Virtual Machine Manager 2008 tool to migrate physical and virtual servers into native Hyper-V virtual guest images.
- When considering adding a Windows 2008 server to an existing Windows 2000/2003 Active Directory environment, consider implementing Hyper-V virtualization, which has proven to be pretty easy to implement and provides a lot of value to organizations.
- Consider using the snapshot capabilities built in to the Hyper-V Administration tool before patching or upgrading a virtual server system. That way, if you need to roll back, you can roll back to a copy of the virtual image right before the update was applied.
- Use Terminal Services in Windows 2008 to provide administrators direct access to a limited number of servers they need to remotely access.
- Use System Center Virtual Machine Manager 2008 to create administration and delegation groups for the centralized administration management of server systems.
- Leverage the capabilities of stretch clustering in Windows Server 2008 to provide redundancy across a WAN link for virtual guest sessions clustered between multiple host servers.
