Whether you virtualize desktops or critical business applications, the dynamics and complexities of virtualized environments can cause significant performance and user experience issues that can diminish the benefits of virtualization and risk interruption of critical business processes. The toughest performance problems are the ones where users call and complain that "my application is slow". IT administrators often struggle to determine the root-cause of the problem and restore service levels: Is it the application server? The virtualization layer? Is it the network? Database? Storage ...?
Join our live webinar with virtualization experts Dave Bartoletti (Forrester Research) and Srinivas Ramanathan (eG Innovations), and find out how to deliver:
• Reliable performance assurance and user satisfaction
• Complete performance visibility across your virtualized environment
• Automatic, rapid root cause diagnosis for even the most complex performance problems
• Pre-emptive problem detection and alerting before users call
• Rapid ROI through right-sizing and optimization

  • 26. © eG Innovations, Inc | www.eginnovations.comMyth #1: Virtualization makesperformance management easier Scope for performance management remains the same 10 servers, 30 guests => 300 virtual machines to monitor New elements and features that need to be managed Hypervisor, datastores, LUNs, resourcepools, cluster, DRS, vMotion, snapshots, vSwitches, … Higher complexity because of resource sharing across VMs VMs share CPU, memory, disk, network resources A single malfunctioning application in a VM can impact performance ofall other VMs Performance management is more difficult with virtualization

  • 35. © eG Innovations, Inc | www.eginnovations.comThe New Reality! Virtualization makes performance management more challenging. Conventional management tools not sufficient to handle the newdependencies and dynamicity that virtualization introduces. IT operations teams now need virtualization-aware, unifiedmanagement solutions 360 degree visibility into every layer, every tier - networks, physicalservers, virtual machines, hypervisors, storage, applications Correlation across these diverse metrics to pin-point the root-cause Management tools need to be domain-specific – VDI vs. virtualserver
