Lessons Learned
• Aligning with the organizations goals.• Understanding your environment
challenges.• Adopt new technologies to improve
performance and utilization of resources.
• Establish baselines and monitor them.• Embrace change. • Make a plan and take action.
Best Practices• Tap every storage port and collect data at the
fabric layer.• Use purpose-built tools to monitor performance
and check for bottlenecks.• Use vendor best practices.• Ensure infrastructure visibility to all teams.• Build collaborative team environment.• Implement thin provisioning to increase disk
utilization at the pool level. • Use virtual server tool set to thin provision at
the host level.
Best Practice Example: Monitor ISLs
• Proactively detect ISL physical errors before they affect users.
Best Practice Example: Measure Cache Performance
• Real-time views into caching
Best Practice Example: Measure LUN Performance
• 5 LUNS appear overloaded
Best Practice Example: Monitor vSphere Server Utilization
• Determine which servers are CPU & I/O bound
Best Practice Example: Monitor VMware Read/Write Latency
• vCenter latency data uses averages; use VirtualWisdom to measure actual read/write latency
Best Practice Example: Monitor Memory Utilization
• Indicates that there are underling memory configuration issues.
Best Practice Example: Measure LUN Utilization
• Determine which file systems are most over allocated based on percentage of utilization.
Best Practice Example: Measure Storage Utilization
• Determine which has the most available space.
Summary
• Greater visibility into virtualized infrastructure.
• Rapidly identify and eliminate problems.• Increased reliability and performance.• Prepared for the challenges of server
and storage virtualization.• We are able to plan more effectively.• Our hospital administration is happy.
