Important LessonImportant LessonStorage infrastructure overhaul accounts Storage infrastructure overhaul accounts

for largest investment in virtualization projectsfor largest investment in virtualization projects

Why? Robust, shared SANs are necessary to:

• Handle throughput ∙ Load balance servers• Migrate workloads ∙ Fail over machines

Problem Prohibitively expensive storage systems proposed

for High Availability & Disaster Recovery• Projects stall or fail to meet operational goals!
