Application Awareness: Large Australian Bank Objective

• Maintain high availability of business critical application but get benefits of virtualization • Obtain application visibility within VMware virtual environments

Solution

Products:

Database:

Storage:

Applications: Custom banking applications, Microsoft SQL Server, various banking applications Platforms: Windows Server 2008 R2 & Linux Projected Results

• Achieved four nines (99.99%) availability in VMware virtualized environments • Reduced Windows/Linux application specific administration time by being able to administrate SQL and Custom applications from a vCenter plugin • Maximized their VMware investment by being able to virtualize business critical applications and utilize VMware features such as DRS & SRM
