Today, Server virtualization is one of the most vital technologies in IT departments. Server Virtualization reduces operational and capital expenditure through consolidation, rapid server deployment and cost-effective disaster recovery. However, for many organizations server migration takes way too long, is way too difficult. What is the true impact of virtualization migrations on organizations, and how can automating backup simplify and shorten the migration process?
The path to server virtualization is not always smooth. Many organizations face challenges, some of those include the following:
• Migrating servers takes too long
• Migration processes are difficult
• After migration, backup impact limits virtual machine density
Migrating physical systems to virtual machines invariably results in some amount of system downtime. The key question is how much downtime can you expect? The average time to migrate from physical to virtual machines is 5-11 hours, but that is only because most IT departments aren’t using all the tools that are available to them in order to lessen the downtime.
The gap between 5 hours and eleven hours in migration times can be attributed to the wide range of tools and techniques used. Some take an extremely manual approach to the process, by creating virtual machines, installing applications, then copying data sets or restoring them from backup images. While others use tools that partially automate the process, when they could be using tools that help automate operations end to end. Many may be spending considerably more ti me than necessary for these operati ons because they aren’t making use of what is available to them. IT personnel should carefully investigate their options for P2V conversions.
The degree of difficulty is a matter of perception. One persons idea of a difficult task can be another’s routine operation, even if they are doing the exact same thing. This can be explained to some degree by the choices made about procedures and tools. As an organizations system complexity grows, it becomes more difficult to successfully coordinate migrating multiple machines and/or data sets which comprise a single application.
Protecting virtual machines after the P2V migration is complete is essential for organizations. Traditional file based backup methods don’t always work well in a virtual environment, because they were designed for physical servers. Expensive resources were being wasted when only one applicati on was run on a server. Users are now faced with running multiple backups from a single system, producing a tremendous amount of strain on already limited disk and network resources.
Backup processing often constrains the amount of virtual machines that can be hosted per physical server (“virtual machine density”) and limited density results in decreased ROI as more physical servers are needed to run virtual machines.
