Challenges of Virtualization
The one-application-per-server paradigm has led to incredible inefficiencies within most IT organizations—with most single-application servers running at much less than full capacity. Inefficiencies in labor, power, cooling and space utilization have prompted many enterprises to consider virtualization—the ability for one physical server to simultaneously accommodate multiple applications and operating systems.
Virtualization comes with its own challenges, however. IT needs a solution that enables proper implementation planning and ongoing monitoring and management of these storage virtualization technologies to maintain their critical performance.
Business Value of Virtualization
IT administrators can:
- Easily view the status of virtualized systems with clear, delineated monitoring of physical and virtualized hardware and applications
- Predict future virtual operating system and application performance
- Correlate the effect of one virtual system on others on the same hardware platform
- Simplify troubleshooting efforts and provide faster mean time to repair
- Perform detailed analysis of virtualized application performance
Business managers can:
- See the financial effect of virtualization technology deployment through business impact reports
- Understand the future effect of virtualization as it relates to business performance through trend reports
