Walter Scott has made a very good article on the topic of virtualization in the SMBs.
After a short introduction, Walter goes trough some technological issues:
- Deploying a Server: Migration from physical to virtual, virtual to physical, virtual to virtual and physical to physical.
- Hardware and Software Support: Support for multiple hardware platforms and operating systems, including both 32- and 64-bit servers as well as VMware, Microsoft, XenSource and Parallels virtual environments.
- Customizing the Migration Process: Migrate an entire system or specific files to another server.
- Working with Data: Migrating either live data or data at rest with either an on-line or off-line migration with minimal disruption.
- Disaster Recovery: Take a backup image and migrate that to a new server for historic data retrieval purposes.
The conclusion is Use the right tool for the job.
