19 DCIM Evolution Roadmap 23 lity Capabi Real time data center What do I have? Basic Remote data access Ad hoc processes Limited tools Unclear roles Problems not understood What is it doing? Reactive Monitor / Alerts Status / Health views Little prioritization Tools are isolated Few standards Simple KPIs Problems understood What should ldi do? Proactive Real-time data Basic information models Policies defined Collaboration Holistic tools KPIs aligned to objectives Problems are anticipated Value Real time, resilient data center How do I Improve? Optimized Predictive modeling Root cause analysis Automated policy and exception management Active identification of cost reduction Avoid problem situations Do it for me! Autonomic Automated policies Auto-Response uo se to events Self-diagnosis / healing Tight integration to business processes 23
